Today i took the opportunity to use a Sony NEX-7 [Crop-Sensor] with a Sony-Zeiss Full-Frame 35mm 1.4f lens.
I have recently read that using a full-frame lens with a crop sensor may not produce better results than using a lens designed from a crop-sensor camera and in fact the images will be less sharp.
When starting out, many photographers choose to go with a crop body and invest in full frame lenses. This is usually recommended as a good approach as you can keep your lenses and swap out your body for something newer down the road, eventually leading to that high quality full frame sensor that you always wanted. However some experts, especially Tony Northrup, claim that starting out with the full frame lens and crop bodies does not provide you with the sharp images.
In my case I had a top end full frame camera [Canon 1DSIII] with a set of very expensive glass and I was not at all happy as the combination was way too heavy and totally unsuitable for street photography. About five years ago I decided that I needed a better solution and after using a Sony NEX-5 for about a year I decided to purchase a NEX-7 and switch from DSLR to Mirrorless [at the time that was a big gamble]. In theory it would be possible to use my Canon lenses with the NEX-7 but in reality it was not a workable solution. The NEX-7 featured a crop-sensor so I purchased a set of suitable Sony lenses and they were not expensive.
My reason for getting the NEX-7 and associated lenses was greatly reduced weight coupled with the fact that my equipment did not attract unwelcome attention.
The NEX-7 performed way beyond my expectations and I was really pleased and then towards the end of last year because the camera was giving problems at random I threw all logic out the window and took an ever bigger gamble by purchasing a Sony A7RMkII full frame mirrorless camera which is larger and heavier than the NEX-7.
To be honest, there is no comparison between the two cameras, the A7R is very much superior and while it is heavier it is actually easier to use. Also the Canon lenses actually work with the A7R but using the necessary adaptor was a pain and added weight. However the Canon lenses showed what the A7RMkII could do so I decided that maybe I should consider getting some native Sony FE prime lenses and then I discovered that they all were expensive and heavy [ unless I got manual focus lens such as the Loxia ]. Anyway I ended up with a set of primes [and no cash] but I now have serious weight issue especially when I travel.
I was planning to use the NEX-7 as a backup or when I travel but the crop-lenses are not very good so it would make no sense to leave my full-frame lenses behind so a possible solution would to bring along one of the FE primes [35mm 1.4f] but then I came across discussions online claiming that FE lenses underperform when used with a crop-sensor. Of course there is another issue in that the NEX-7 is at the end of its life and needs to be replaced by something like the A6300 but as I already said I have no spare cash.

With its extremely high-resolution image sensor in full-frame 35-mm format and cutting-edge image-processing system, the Leica M9 is uncompromisingly dedicated to capturing images of the very highest quality. The photographer may choose between image storage in JPEG format for fast processing, or as raw data in DNG format that supports a multitude of post-processing options. Alternatively, both formats may be stored simultaneously. In the DNG format, photo- graphers may also choose between a compressed, but faster and greater space-saving option, or an uncompressed version that preserves maximum image quality.
Of course the Leica M9 offers photographers access to the complete Leica M lens system lenses, long acclaimed by experts and users as the best in the world. Its development began in 1954, and the M-System has been continually advanced and improved ever since. The high-resolution, full-format image sensor of the M9 fully exploits the performance of legendary Leica lenses from corner to corner.
It is hardly unusual that a Leica, once owned, becomes a lifelong companion. This also applies to the digital M9: Its closed, full-metal housing, crafted from a high-strength magnesium alloy, and its top deck and bottom plate machined from large blocks of brass, provide perfect protec- tion for its precious inner mechanisms. The digital components and shutter assembly of the M9 are similarly constructed with endurance in mind. Free firmware updates ensure that the camera benefits from the latest technology. In short: The Leica M9 is an investment for a lifetime.
Discretion and unobtrusiveness are particular strengths of the M-system. In operation, the shutter of the M9 is as quiet as a whisper. An extremely low noise level when cocking the shutter is ensured by a sophisticated motor and gearing system. In discreet mode, the shutter is only cocked after the photographer‘s finger is lifted from the shutter release button when, for instance, the camera is concealed under a jacket. When shooting handheld at long exposure times, or whenever extreme steadiness is essential, slight pressure on the shutter release button in ‘soft release’ mode is sufficient to trigger the camera. In addition to these advantages, the fact that the combination of camera and lens is significantly more compact than any other full-frame camera system contributes to the fact that M photographers are frequently unnoticed and often simply blend into the background.
The Leica M9 adapts to its intended uses in a seamlessly flexible manner. Its sensitivity ranges from ISO 80 for wide-open apertures on bright days to ISO 2500 for low-light image capture. Very low noise levels and finely detailed images are achieved throughout the sensitivity range, even at the highest ISO settings. Very low image noise characteristics, an extremely bright viewfinder/rangefinder, low-vibration shutter and the availability of super fast lenses make the M9 the perfect camera for available-light photography.
The Leica M9 aids photographers with automatic functions whenever they’re required, but it never dictates how to shoot or interferes with the picture-taking process. Depending on the light level, the automatic ISO shift function increases the sensitivity of the camera as soon as the shutter speed falls below a hand-holdable value. At the same time, it also limits the shift to a maximum value determined by the photographer. This means that correct exposure without camera shake and the lowest possible sensitivity is always available to guarantee the best possible image quality in all situations. In addition, the M9 also offers automatic exposure bracketing with a user-selectable number of shots and exposure increments. This function ensures that even high-contrast subjects are perfectly captured.
Like every M camera of the past half century, the M9 is concentrated, by design, on the most photographically relevant functions. Its manual focusing – based on the combined viewfinder and rangefinder concept – and aperture priority exposure mode enable photographers to achieve maximum creative expression without imposing any limitations on their creative freedom. In combination with the 2.5-inch LCD monitor on the back, the simple, intuitive menu navigation system controlled by only a few buttons ensures rapid access to the entire range of camera functions.

10 ALL INFORMATION AT THE PUSH
OF A BUTTON
The CCD image sensor in the M9 was specifically designed and developed for this camera and offers full 35-mm film format without any compromises. All M lenses mounted on the M9 offer the same exact angle of view they had when shooting film material and therefore can now be used to an optimum effect. In other words, all the outstanding characteristics of Leica M lenses are now fully maintained for digital photography as well. In short, the high resolution and superior image quality of the M9 has the ability to fully exploit the enormous potential of M lenses.
In the case of the M9, it wasn’t a matter of modifying the lenses to match the image sensor, but rather the other way around. Our dedication to further developing the image sensor has resulted in a component perfectly matched to its intended role in the very compact M-System as well as to the performance of M lenses. The special layout of the micro lenses found in the M9 sensor makes it tolerant of oblique light rays impinging on its surface, thus assuring uniform exposure and extreme sharpness from corner to corner in every image. As a result, future Leica M lenses can be designed and optimized with uncompromising dedication to the achievement of the highest performance and compact construction. A newly developed sensor filter ensures the suppression of undesirable infrared light. The conscious decision to do without a moiré filter, a cause of image deterioration through loss of resolution, ensures maximum resolution of fine detail. The optimized signal-noise ratio of the CCD image sensor reduces the need for digital post-processing and ensures that M9 images possess an unrivaled and natural visual impact.
The key control element of the M9 is an intuitive four-way switch and dial combination used in conjunction with the 2.5-inch LCD monitor on the back. To set the ISO sensitivity, simply maintain light pressure on the ISO button while simultaneously turning the dial to select the required setting. All other functions important for everyday situations are quickly and easily accessible by pressing the set button: white balance, image-data compression, resolution, exposure correction, exposure bracketing, and programmable user profiles. The user profiles can be programmed with any combination of camera and shooting settings, stored under an assigned name, and accessed quickly whenever required for a particular situation. An additional pre-defined snapshot profile is also available. In snapshot mode, the M9 automa- tically sets as many settings as possible, thus providing a valuable aid to spontaneous and discreet photography. All other functions – from automatic lens recognition via six-bit lens- mount coding and selection of the required color space to cleaning of the sensor – are easily found in the clearly arranged main camera menu.
Pressing the “info” button in shooting mode displays the precise charge level of the battery, the remaining number of frames on the installed memory card, and the most important basic shooting settings, for example the shutter speed, on the camera’s brilliant 2.5-inch LCD monitor. In image-view mode, users can switch between an image-only view (with a zoom option up to single pixel level) or access other information by simply turning the dial. The available data includes information on the ISO sensitivity setting and shutter speed in use, plus a precise histogram display.
The Leica M9 embodies the heritage and amassed experience of more than five decades of the M-System. It is also, simultaneously, a digital system camera at the absolute pinnacle of modern technology. For Leica designers, photography has always been their prime concern – whether film or digital. The combination of an extremely efficient image sensor, the latest digital components, and the classic viewfinder/rangefinder principle – consistently optimized over many years – make the Leica M9 absolutely unique in all the world.

WORKFLOW SOFTWARE IS INCLUDED
The digital image processing workflow solution Adobe® Photoshop® Lightroom® is included in the M9 package.
The M9 is supplied complete with Adobe® Photoshop® Lightroom®, a professional digital work- flow solution for Apple Mac® OS X and Microsoft Windows®. The software is available as a free of charge online download for all Leica M9 customers. This also ensures that the latest release is always readily available. Adobe® Photoshop® Lightroom® offers a vast range of functions for the administration, processing, and exporting of digital images. If the images from the M9 are saved as raw data in the standardized and future-proof Adobe Digital Negative Format (DNG), then the sophisticated and precise processing options of Adobe® Photoshop® Lightroom® guarantee direct and extremely high-quality image processing with maximum image quality. At the same time, the 16-bit per channel color information captured by the image sensor is maintained throughout the processing workflow from image import to image export, ensuring that the most delicate tonal differentiations are preserved in maximum quality after completion of the post-processing sequence.
The Leica M9 can display a precise RGB tonal value histogram of the captured image after each shot, and also offers optional integration of the histogram in the automatic image view display. The clipping warning display over- and underexposed zones in each image, warning the photographer of potentially unusable images. An innovative feature is that the histogram is recalculated every time a new part of the image is viewed, thus enabling a precise quality assessment of small image areas and even the finest image details.

"Magic Wire" is so called because of detecting proximity to antenna.
THE MAGIC WIRE
As shown in the diagram, the input tube is a type 6R7 duo-diode triode. The triode section forms the oscillator, in conjunction with the coil L1 which is center-tapped to the cathode. When the triode section is oscillating, the r.f. voltage developed from cathode to ground is impressed on the diode section, causing current to flow through R2 and making the diode plates negative with respect to ground. The control grid of the 25L6 power tube is connected to the diode plates of the 6R7 and consequently a negative bias is placed on the grid which reduces its plate current to a very low value. As soon as the triode ceases to oscillate, there is no longer any r.f. voltage applied to the diodes, the voltage drops and the 25L6 draws high plate current, causing the relay to operate.
It will be noted that no rectifier tube or filler circuit is required in this design, yet the instrument functions on either a.c. or d.c. On a.c., the 6R7 oscillations and the 25L6 draws plate current only on the positive half-cycles. This principle effects a considerable saving in construction cost and in the size of the instrument.
After the parts required have been obtained, the first step in building the unit is to make the chassis, which consists simply of a piece of 16-gauge aluminum or steel bent and drilled in accordance with the plan shown. The front panel, which is included with the standard 6 by 6 cabinet, is drilled and a hole and grommet are placed in the rear panel. The oscillator coil is made by winding 100 turns of No.28 d.c.c. wire on a one-inch bakelite tube 3-1/4 inches long. A tap is brought out at the center of the winding. When the winding has been completed, the entire coil is dipped in a hot half-and-half mixture of beeswax and paraffin to keep the winding in place and exclude moisture. The sensitivity of the outfit is largely dependent upon the efficiency of the coil, so it should be carefully made. C1 is mounted on a small piece of 1/8-inch bakelite, because it must be insulated from the panel.
Wire the chassis first, starting with the heater circuits. Do not connect in the power cord until all wiring has been completed. The shield of the 25L6 is connected to its cathode, the shield of the 6E7 to the heater terminal which goes directly to the line. When all the main wiring has been completed, bring the power cord through the rear panel hole, and solder the three terminals to the terminal strip. The antenna wire is brought in through a rubber-grommeted hole in the top of the cabinet and connected to the stator or plate terminal of C1. A knot in the wire will relieve any strain on this connection. Stranded wire is preferred for the antenna.
The capacitances of C1 and C2 are largely dependent upon the length of antenna wire desired. If only 4 or 5 feet are required, C2 may be omitted. On the other hand, if the wire exceeds 15 feet, C2 will have to be larger than the value given. If the capacitance of C1 were made large (say 150 mmf. or more), C2 could of course be omitted but then the adjustment would become too critical.
The relay employed is a 3,000-ohm plug-in type of standard manufacture. It is a double-pole model and will handle a non-inductive load of 100 watts. It is somewhat more sensitive than is required and any other good relay of 1,000 ohms or more resistance should be suitable. The capacitor, C4, is shunted across the relay coil to prevent chattering. It may be advisable, in some cases, to put a 0.1 mf. paper capacitor across the relay contacts to stop sparking on heavy loads. It is better practice, however, to use a separate power relay when operating any but light loads.
In operation, the antenna wire is strung out well away from grounded metal objects and a 110-volt lamp is plugged into the outlet on the panel. When the tubes have heated, the lamp should light when the antenna wire is touched. If it lights without touching the wire, C2 should be screwed down until the lamp goes out. These adjustments should be made with C1 about one-half mashed. The panel may then screwed in on the cabinet and final adjustment made. This is done by gradually adjusting the vernier knob of the dial until the light remains lit when adjusting but goes out when the hand is removed from the dial. This may be carried to a point where the light will flash as soon as one approaches within 3 feet of the wire or instrument. It is better not to aim for such sensitivity, though, since it will vary somewhat with line voltage. A good, practical and stable point is about six to fifteen minutes or so for the instrument to acquire a stable point of operation owing to its sensitivity.
