DC's own Sensor Ghost playing in Lost Origins Gallery in Washington, DC's Mount Pleasant neighborhood.
2 of 2 new toys. Looking for flare and sensor bounce. Both are reasonable, one small flare lower left of sun. Increasing contrast higher than normal does show some weak sensor reflections. Pretty good for my tastes. Rendering is very appealing to me, great, love it.
At 66, it is art right? It's like everything else in life, you develop an appreciation of your liking. I'm new to this but I think barrel distortion is appreciated, and a little mid frame fall off, nice in this over bright digital world, can be restful. Again, to me, subjects at this angle need to be an element in the group.
Once I find my focus spot, This will be a great addition to my light lens combinations taken on backpacking trips. 12 - 35 is great point and shoot focal lengths. 50 and above require focusing skill I yet to perfect and don't know if possible due to failing visual acuity. (It's not the equipment) When I take my zooms, I tend to be at one extreme or the other. Though I adore my 12-24 f4, it is heavy and bulky for walking chest mount. These eight ounce high performance lenses are nice. On a 2 pound budget, that could mean 4 lenses. Work that into your cross country photo shoot plan. Seems to me, Adams had 3 focal lengths, 35, 50 and 85. I like 12 to 35. The 90 is my Le Conte Canyon lens. On most trips for 2022 I'll take 12, 21, and 35 primes except for the End of Road to MTR via Lake Basin leg when I'll take the 90.
Both lenses , the 90 and this 21, together weigh 1 lb 2 ounces. :)

The first thing to say is that each electronic sensor has a protective filter over it, so we are not actually touching the electronics. That would be a disaster. Most people send the camera off for a service and a clean and that's a very good idea. After all this is an expensive investment and we want to make sure our camera works as well as possible for as long as it can.
But, it is quite easy to clean your sensor at home. All you need is a kit (like the one I've shown). This includes sealed sterile swabs and a little cleaning fluid (they are essential - do not try to clean your sensor with a cloth where you can scratch the dust into the sensor filter). There are also many videos on YouTube showing you how to use these dust cleaning swabs, but provided you get the right size for your camera (mine is full frame) a simple swipe will suffice.
For a DSLR you obviously need to lock your mirror up before the clean, and then lower it immediately afterwards. Then with the other side of the swab give your mirror a quick wipe as well. Do not apply too much pressure. After all, these are only tiny dust particles - you should not have any dirt.
My Leica D-Lux 7 which I used to take these pictures has a fixed lens, so it will never need its micro-four-thirds sensor cleaned.

An important thing to remember is that even though pixel sizes keep getting smaller and smaller, the technology is advancing, so the smaller pixels are more efficient at collecting light. For instance, the Sony A7rII is back-illuminated which allows more photons to hit the sensor. Semiconductor technology is always advancing, so the brilliant engineers are always improving the signal/noise ratio. Far higher pixel counts, as well as better dynamic ranger, are thus not only possible, but the future!

View your artistic mission into photography as an epic odyssey of heroic poetry! Take it from Homer in Homer's Odyssey: "Tell me, O muse, of that ingenious hero who travelled far and wide after he had sacked the famous town of Troy. Many cities did he visit, and many were the nations with whose manners and customs he was acquainted; moreover he suffered much by sea while trying to save his own life and bring his men safely home; but do what he might he could not save his men, for they perished through their own sheer folly in eating the cattle of the Sun-god Hyperion; so the god prevented them from ever reaching home. Tell me, too, about all these things, O daughter of Jove, from whatsoever source you may know them. " --Samuel Butler Translation of Homer's Odyssey

The Gharials or Gavials (Gavialis gangeticus) are pure fish eaters, though a crab or two may be unlucky to be swallowed by these majestic river dwellers. They are the kings of few North Indian rivers, especially Ganges! Since they spend most of their time in water, their eyes are telescopic, placed well on top of their heads. This allows only their periscope-like eyes to come out of water when they surface. Also notice the thin translucent membrane called as 'Nictating Membrane' that is there in the frontal part of the eyes, ready to move backwards to protect the eyes once the animal is submerged. This acts as a water-screen or swimming goggles, which improves the vision of the submerged gharials. This morphological adaptation is there in all 23 crocodilian species around the world!
Seventh Sense: Note that their eyes with vertical pupil are bordered with small pressure sensors (clearly visible in the lower eyelid) that appear like dark spots. With these, they are able to assess the changes in water pressure around them and gives them better navigation and fishing efficiency even in darker and murkier waters, where vision might not be of great assistance. Moreover, these pressure sensors sense the movement of fish and other elements around their mouth (since their jaws are ridden with several of these), leading them to accurately catch fish. Even though this is an extension of touch mechanism, but can be recognized before touching something, since the fish are too smart to swim close to or touch a hungry gharial. The fish have a "lateral line" running along their body from mouth to tail that acts as their pressure sensing mechanism.
Fishing Strategies: Since both prey and predator have these, the predator has 3 strategies. It either waits without any movements for the fish to swim close by to swiftly snap shut its mouth and get its meal. Otherwise, it frightens and chases fish to nooks and corners close to the river beds and bends. Once they are trapped between its huge body and the bank, it feasts on them. The third way is to capture the overconfident huge fishes that do not care about the presence of this huge reptilian in their vicinity.
The dark slit behind the eye is its ear, which also is shut in a watertight manner after diving.

My journey into mirrorless started a little over 2 years ago with the purchase of the Sony NEX 6 - intended to allow me to use some inherited Leica M-mount glass on a digital camera (for a variety of reasons is a Leica rangefinder not an option for me). Worked out reasonably well - but the crop factor impacted the usefulness of the lenses somewhat (which led to the purchase of a Voigtlander Color Skopar 21/4 lens for some wider FOV).
Those FOV issues were resolved with the purchase of the full-frame Sony A7 a year or so later - albeit now the thick cover glass of the sensor became an issue because it affected corner performance (corner smearing) and/or caused a color cast that needed post-processing work to remove (sometimes not possible). Nonetheless, I ended up with a compact little system consisting of a Voigtlander Ultron 21/1.8 (the 21/4 shows uncorrectable amounts of color cast), Voigtlander Nokton 40/1.4 (replacing the Leica Summicron 35/2 ASPH (corner smearing)), and Leica Summicron 90/2. There's also a Leica Apo-Telyt 180/3.4 that had its mount changed from Leica-R to Nikon F; due to its size and the need for another adapter, it's not a lens I carry with the A7 system all the time.
Debated for a some time to drop most of my Nikon system (i.e. the full-frame D700) in favor of a Sony E-mount system. Sparsity in lens selection from Sony/Zeiss as well as third parties (will change over time but I don't want to wait years to assemble a system), the fact that often Sony/Zeiss lenses cost more than those from/for Nikon, no or little size advantage of the native E-mount lenses over those from Nikon (resulting in more disproportionate size difference between lens and camera body and hence handling issues), and the short battery life that forces one to carry at least four spare batteries for a day of shooting finally tilted the scale for me - and I purchased the Nikon D810. Traded the Nikon 70-200/2.8 VR for the 70-200/4 VR (the bulk and weight of the f/2.8 zoom caused me to leave it home more often than not).
A set consisting of the A7, Zeiss 16-35/4 and Sony 70-200/4 saves only about a pound of weight compared to the D810, AF-S 16-35/4 VR and 70-200/4 VR - almost entirely due to the smaller and lighter A7 body. And since the lenses are almost the same size as their Nikon counterparts not much space saving is accomplished either. And either the A7 is quite loud for a mirrorless, or the D810 rather quiet for a DSLR - there isn't really much of an audible difference.
I also didn't want to give up the Sigma 35/1.4, the Nikon 85/1.8G (with the Batis 85/1.8 there's finally an alternative available for the A7 - even though it costs twice as much as the Nikkor) or the Sigma 150/2.8 Macro (no equivalent available from Sony/Zeiss). Very recently, I added the just released Sigma 24/1.4 to my bag (faster and cheaper than the just released Batis 25/2) - like the 35/1.4 a bargain for what it delivers (the just released Zeiss Distagon 35/1.4 costs twice as much). A 80-400 rounds out my system - again with no alternative with a native E-mount.
The decision to go mirrorless is a personal one and everyone needs to draw their own conclusions. I made mine - I keep the A7 for use with a small set of compact manual focus lenses but my main system for some time to come will be DSLR-based. If one compares the A7II and the Nikon D750, then one will realize that a DSLR can be shrunk to almost the level of a full frame mirrorless body and that the weight differential becomes negligible. For lenses, some weight saving can be realized, but in terms of size, there's precious little difference between mirrorless and DSLR lenses. Mirrorless definitely needs more powerful batteries and the way I see it, one of their advantages over DSLRs is the omission of the mirror and the concomitant reduction in complexity and production costs. AF performance (especially continuous AF) will eventually reach DSLR level and EVF lag is already reduced to a level that makes it negligible. I think we will eventually see some hybrid finders in DSLRs - allowing to see, for example, a histogram, a magnifier, and a two-axis level superimposed on the focusing screen.
Edit November 2015: Something I had not even considered in my decision because I only used the Sony with manual focus lenses - the AF performance is nowhere near that of a high-end DSLR. There are a sufficient number of reports that demonstrate inconsistencies, slow performance in low light, poor tracking, and the inability to quickly select a focus point yourself. Also, in continuous mode shooting, EVF blackout is an issue - it's actually substantially longer than that in a DSLR caused by the mirror movement. Where is the advantage of mirrorless in that aspect? By now we have the A7RII and also a A7SII - those issues still remain. Pretty soon, the MkIII version will appear - let's see if they have reached the AF performance level of a Nikon DSLR yet.
And if it isn't blackout - then it is the inability of the EVF to update quickly enough - try tracking something that moves and you most certainly can't rely on the viewfinder - the subject is never where the viewfinder shows you it is - much unlike the OVF in a DSLR. An A7RII in Hi speed drive mode has virtually no blackout (much unlike the Lo speed mode) - but the EVF can't follow and at least from my testing I have to conclude that AF can't follow and track either under these conditions.
A lot of reports want to put the newly released A7RII on the same level as the D810. And I suppose for some applications that is true (or the Sony may actually be more suitable). As I understand it most certainly for video - which is of no interest to me at all. And with the overheating issue of the A7RII you would be limited to shooting less than 1/2 hour anyway ;-(.
The resolution difference will be barely noticeable - and your image IQ will be influenced more by your lens choices.
The main differences are EVF vs OVF and the AF performance - for the former there are advantages on either side; for the latter, there's even at the MkII stage of the Sony A7 Series nothing to be gained over the Nikon.
It is very hard to come by unbiased reviews; when making your own decision, keep an eye out for the things that matter to you - don't fall for the hype. At this point, the choice between DSLR and mirrorless is still one between a mature system and one that has a ways to go to get there.

Technically, a twin to the Panasonic Lumix DMC-LC5, the Digilux 1 was introduced in 2002.
Equipped with a 1/1.76" CCD sensor with an effective resolution of 3.9 megapixels, it can shoot photographs in JPEG or TIFF format, but no raws.
The lens is rather good - though it probably is more Panasonic than Leica, moniker notwithstanding.
It has a fold-up sun-shade that is screwed into the tripod mount but I never use it because on mine it apparently distorts the plastic camera case and the battery then tends to lose contact.
The viewfinder is rather useless, you'll be using the screen for focusing and image composition.
The autofocus is as reliable (or unreliable) as that of modern compacts.
Actually, the Digilux 1 is quite a handful, The term "compact camera" is not really appropriate. It has a very plasticky feel to it, but mine, despite its 15 years of age, works fine (except for the problem when attaching the fold up screen shade).
If you asked my opinion on this camera, I'd say this:
The lens is running rings around the sensor, which is quite normal. Back in 2002, optical engineering was a mature field, while consumer digital imagery was not. So we have here a very good lens fixed to a not really very good sensor.
The issue is not resolution - 4 MP is quite enough for a compact camera. It's also not colour rendering - the sensor acquits itself of that task quite well. It's a CCD, and I always had a preference for those. No, the problem is noise, even at low ISO values.
The image was taken with a Canon EOS600D and a Leica Summicron-R 35 mm lens.
The sensor noise is quite visible
