I mean no disrespect to you or your gear but looking at your gear list in your signature, I see you use what most people consider as an "old" camera and lens set up ... so are you suggesting that the gear that you are currently using is limiting your creative abilities? are they not good enough for you? Are you suggesting that 15+ year old lenses are not able provide enough resolving power for your EOS 30D? ...
The photographic gear that I have is gear that works for me. In no way am I dissatisfied with the 30D and the three lenses I own. My point is that every year Canon brings out new cameras and lenses; and every year I don't "upgrade" my gear because none of the new offerings really interest me.
The EF 24mm f/2.8
is a good lens, but ... (1) my c.
1971 Super-Multi-Coated TAKUMAR 1:3.5/24
is better in all departments; and (2) the old micro-motor AF without real-time manual focus is really old technology. So why shouldn't I expect an updated version, with USM, after 24 years in production? (I may just mention that the 24mm is mostly used at f/11.)
I did buy the EF 40mm f/2.8 STM
, but sold it again - didn't like the colours. I also sold my EF 50mm f/1.4 USM
when I dumped my Canon film gear - a 50mm works on FF, but not CF ... for me that is.
... but no one can "make you pay" anything ...
Canon is. Take the EOS 6D and the (discontinued) EOS 5D Mk.II ... image that FF sensor is now a CF sensor (same MP, etc., just CF instead of FF) and what do you get ... a "Rebel" in disguise.
