Today, I am in a black and white mood.
Of course I forgot to bring the Kiev 4 along with me, and so only the Canon 350D is immediately available. Now you can always take photos with your colour bayer array sensor digital SLR, but you immediately lose many of the benefits of B&W photography. Reduced dynamic range as well as less sharpness due to bayer arrays and anti-aliasing filters. If only there was some sort of full frame B&W sensor with a full 10 stops (or more) dynamic range.
Alas, there is no such thing (apart from one attempt from Kodak in the past); and the immediate future doesn’t hold much promise either, due to a complete lack of demand. The lack of demand is of course due to the fact that not many people want a camera that does only B&W, especially when it is extremely easy to convert your colour digital photos to B&W anyway (despite the drawbacks).
So I wish once again, for a modular digital system. Not something like Leica’s digital R system, where they separated digital camera, from a glorified lens holder. No I wish for a system where as much as possible is reused in the camera itself, with little more than a cartridge encased sensor being the easily replaceable part. I obviously a system like this is far off, and probably further than it needs to be, since camera companies benefit from the constant rebuying of bodies every time a new sensor is developed.
Now imagine a future where you buy one camera body. The range/cost is defined by the memory bandwidth, shutter speed, autofocus, etc. The sensor is not included, or comes with a basic 1.6x crop sensor, say 12 megapixels and usable ISO up to 3200. Now I decide to splash out and get a full frame B&W sensor for my camera, it is 12 megapixels as well, but with ISO all the way up to 25600. At the lower ISO’s it has a dynamic range of 12 stops, and it’s images are amazingly sharp. Add to this a 2x crop sensor, say 10 megapixels, perfect for nature and outdoor sport; a full frame high resolution colour sensor perfect for extra large prints of landscapes; a lower resolution full frame colour sensor could provide amazing colour rendition and dynamic range.
Suddenly you have system that allows you to carry one camera with you, yet gives you the flexibility to use a sensor that is most suited to the job at hand. Done properly, I would hope you could get the equivalent of 4 digital SLR’s for the price of 2, and throw in the chance of 3rd party sensors (want a Foveon sensor in that Canon body?).
I’m sure there are many technical issues I don’t know about, and these hurdles may never be passed, but one can dream.
