The Royal Tiger!
No wonder they call it as the Royal Tiger....you can feel it when it walks...especially when it walks so close by.
This is the season for Tigers. Ranthambhore and Bandhavgarh are rocking and the sightings have been excellent. To see Tigers, you need good amount of planning and need to study the park and get inputs from the locals.
I plan all my Tiger workshops in such a way that the participants get maximum opportunities to photograph them. Though everyone expects to see Tigers in all Safaris, it hardly happens. But when it happens, you need to be ready to make the best use of it.
I mainly target two kind of Tiger Photography. Close-ups like this one, and showing the habitat like the previous image of T19 crossing the lake with its sub. Of course the 3rd type is the action type where you need lick, planning and skills to capture.
Anyways, enjoy this pic and feel free to share.
Canon 1DX + Canon EF 400mm f2.8 L ISII, ISO 250, f5.6 @ 1/1250, Evaluative Metering -2/3 Stop, WB at 5400K.
A couple of gas station signs found along 66. Old soldiers still standing proud before things long gone.
Nikon DSLRs come in two sensor sizes, FX and DX. FX is Nikon's new moniker for a sensor approximately the same size as old 35mm film which is technically called 135-format. DX is a smaller sensor also referred to as APS-C size. Note that APS-C sensors actually exist in a range of sizes and thus is not an exact size but they're all pretty close. For instance, Canon APS-C sensors are slightly smaller than Nikon's. Even amongst Nikon cameras, DX sensor sizes sometimes vary slightly (by a couple of tenths of a millimeter) depending on the specific model of sensor used in that specific model of camera. The above diagram shows the relationship between FX and DX.
Lenses project an image circle of a certain size. Nikon has a line of lenses which will only project an image circle big enough to cover DX. If the lens does not have a DX notation then it will cover FX (also covering DX).
But what about focal length? For any given lens focal length, the following axioms hold true:
[0] Focal length does not change with sensor size. Apparent focal length as it pertains to Angle-of-View (AOV) or Field-of-View (FOV) however will differ. This is merely an effect of how much of the actual image can be seen combined with normalisation of the final output image to a specific physical size. This is also known as the crop-effect.
[1] That lens on a DX sensor will provide a tighter AOV than on FX thus giving an apparently longer focal-length than 135-format.
[2] That lens on an FX sensor will provide a wider AOV than on DX thus giving an apparently shorter focal-length than APS-C DX-format.
Nikon FX cameras feature an autodetection mechanism for DX in that they will automatically crop into the DX size when a DX lens is attached. This auto-DX feature can be disabled and overridden however.
So what does the auto-crop do? Well currently with the 12MP FX sensors in the D3 and D700, you'll get an image comparable to that from a 5MP DX camera. As newer sensors with higher resolutions come out, the resolution of the auto-cropped DX portion will also increase.
Now since in auto-crop mode, the sensor is basically "throttled down" to DX size, it again means your crop-factour will come back into play and reduce your AOV. It will make pictures taken with say a 200mm DX lens appear to have the same AOV as pictures taken with a 300mm FX-compatible lens.
But what about lens choices, you ask... One thing to keep in mind is that DX lenses are generally smaller, lighter and cheaper. They are also usually available in focal lengths that "make more sense" with regards to AOV and FOV given the crop-factour. Personally, I don't pay much attention as to what's considered an appropriate focal length for a given sensor size. I pick my lenses based on what I think I want in terms of actual AOV. For instance, I primarily use a 24-70mm zoom as my midrange zoom lens but others will tell you that it's "inappropriate" and you should pick the 17-55mm lens range instead. Choose whatever feels comfortable for you and how you shoot.
There are some advantages to using lenses made to cover FX on a DX sensor camera. Because you are only using the DX portion of the image circle, you are taking advantage of the higher quality section of optics nearer the center which some people refer to as the lens' "sweet-spot". This tends to mean better edge-to-edge sharpness and less possibilities for vignetting.
