Should SONY keep producing new DT lens offerings?
I went looking at the Canon site, to see what was happening and I happened to notice that they have include two new lens offering, along with the EOS 7D and EOS 1D MkIV camera introductions.
A pair of kit-style apertures:
- EF-S 18-135mm f/3.5-5.6 IS (MSRP $499.99)
EF-S 15-85mm f/3.5-5.6 IS USM (MSRP $799.99)
Both these lenses are designed for APS-C sensor DSLRs ... and would have limited use on the FF. Obviously, every thing shifts 1.6x (Canon's DCF) to the right, making them, in operation, effectively:
- EF-S 29mm-216mm f/3.5-5.6 IS
EF-S 24-136mm f/3.5-5.6 IS USM
Being "IS" equipped lenses, it probably makes sense that Canon would need to supply these to their users, but would SONY be so "trite" as to add even more dark zoom lenses to their "DT" selection? Personally, I hope this nonsense is over. Attachment 50017
Mount design with NO limitations
It the case of Canon, you are correct. "DT" lenses in SONY Land work on any SONY DLSR, you just have to mode switch to get proper response on the FF-Frame cameras.
I would suggest that making everything "Full Frame" makes for more sales, overall. There are very few people that would select a "DT" lens for their Full Frame camera (be it FF-digital or 35mm-film).
Full Frame membership ... hello, everyone!
Okay, let's say you can get a better result in the knowledge that APS-C sensors are eventually going to become ... extinct. How does that work for you? :cool:
Having cheap, smaller aperture glass sort fails in that regard. If the photographic universe (PU) standardizes on "normal"-sized glass elements for the Full Frame, it eliminates a lot of confusion and any limitation whatsoever. Everything works everywhere. ... oh, how novel. Personally, I am liking that idea ... marrying up the real past and eliminating this weird, awkward (APS-C & H) phase of el cheap lenses we are currently trending in.
The next series of Full Frame sensors should pretty well cement this idea. Attachment 50035
