"DX lenses life"


Grand Rapids, US
          

I've been thinking about getting the D70 which would be my first digital camera. I'm planning on getting the lenses that gets bundled with it. I'm just wondering if anybody thinks that the CCD on DSLR's are going to eventually be at the 35mm range for the average person to afford. If that happens, what will become of the current line of DX lenses? Will DX lenses work with larger CCD's correctly? I know they not recommended to use on a 35mm SLR. I just don't have to waste money on DX lenses if they are going to have a short life span.

I know that the answers will probably be all speculation.

I would say your are out of luck if the sensor grows considerably. If it only increases some then it may work with some vignetting or cropping may occur.

There is a good writeup on the DX format here:
http://www.nikonpro.ca/dx/index.esp?tid=56157c57375a88ef1d0bea46b235f932

Personally, that lens is a great value for the money if it performs well optically. If a lager sensor comes out, you could always sell that lens with the body.

This is a great question.

A couple of years back I would have suggested that Nikon's tradition of backwards compatibility would offer some assurance of longevity of their new products. This has all changed with digital, as the technology advance rate far exceeds that of the film era. Products are being introduced and replaced at such a rate that the philosophy of maintaining longevity probably cannot be fulfilled by Nikon. A good example is the DX flash protocol, it has now been eclipsed by i-TTL, rendering those DX flashes less effective on newer digital bodies like the D70.

Until there is a concrete answer to the Full Frame question, there will be risk associated with buying into the 1.5/DX philosophy. Perhaps the new offerings at PMA will illuminate the issue a bit more clearly.

This is getting to be a very frequent question with a lot of speculation involved that needs some clearing up.

First, the DX format itself: the image produced is smaller (at at least some focal lengths) than that needed to fill a 35mm film frame. If you use these lenses on a film body (or a DSLR with a larger sensor) you will certainly get significant vignetting. The 12-24DX for instance will work fine on film from about 17mm out to 24mm. Wider than this though and you will see obvious problems. At 12mm, the image will be a round circle with a black background. This is not a problem for the intended use though since the DX sensor is small enough that the image circle completely covers it at all focal lengths. If the image circle covered the larger size completely at all focal lengths as well, the lens would not be marketed as a DX lens. Therefore, this problem will exist on all DX lenses at least at some zoom settings.

As to whether this is a problem or not, it depends on how you look at it of course, but instead of repeating myself from another thread, I invite you to review the following post:

Thank you for the good advice. I think Bob states it best that if you want it, get it now because there will always be something different down the road which you'll always be waiting for and never buy anything.

The D70 will cost about the same as an F100.
The D100 cost about as much as an F5.

I think it fair to say the Canon is the only top drawer DSLR of the 3 full frame models available.
It costs about the same as 7 F100's.

How much can an average person afford?

Photography is a bit like archery. A technically better camera, lens or arrow may not hit the target as often as it could if the photographer or archer does not practice enough.

here's an interesting data point: When the F100 first came out it sold for $1499 from B&H. The D100 currently sells for the same from B&H.
