film camera lens on dslr image
iCan
I'm not sure if the question makes sense or not; but I have a 35mm SLR camera; with a 50mm f/1.9 lens on it.
I love the view of that 50mm f/1.9 lens on my film camera; what would be the equivalent of that lens on a DSLR (Pentax K-x)?
Answer
The K-x has a 1.5x FOV crop, so you'd require a 50mm/1.5FOV= 33.3mm lens. Or in practical terms, anything between 30mm and 35mm.
If you want to keep the f/1.9(ish) maximum aperture, Pentax has a 31mm f/1.8. Unfortunately, it's +$900 item: http://www.bhphotovideo.com/c/product/394223-REG/Pentax_20290_smc_Pentax_FA_31mm.html
And to achieve the same shallow depth of field as your f/1.9 on a cropped body (using a 30-35mm lens instead of 50mm), you'd actually have to use f/1.4. You can run the numbers for yourself to verify this: http://www.dofmaster.com/dofjs.html
So, enter Sigma: they have a 30mm f/1.4 for 'just' $440: http://www.bhphotovideo.com/c/product/433041-REG/Sigma_300109_30mm_f_1_4_EX_DC.html The reviews are so-so but there's not much else out there that does the same. For a while I considered getting one for my Nikon D200 (also with a 1.5 crop factor.)

Can a digital camera lens be used on a film camera?
Luiz Pedro
I have a canon 50D and im thinking about purchasing a film camera for school. The lens on my canon is the standard one that came with it. Im thinking about buying a film canon SLR and just wanted to know if the lens from my 50D would work with any. And if it only works with particularly SLR's which ones.
Also if anyone has any recommendations on what film camera to get that would help too.
Answer
The lens that came with your Canon 50D is most likely an EF-S lens which means it cannot be used on a Canon AF 35mm film camera or Canon full-frame DSLR like the 5D or 1D. A Canon EF lens can be used on any Canon AF 35mm film camera or cropped sensor Canon DSLR or Canon full-frame DSLR.
