I see what you're saying also. But I don't think the 40mm has a huge image quality advantage over the new 24mm IS (very marginally sharper in the corners than the 24mm IS) - they were released at the same time after all. And I'd take IS over STM any day of the week, especially when there is no speed difference. And the 24mm IS can be used on full frame cameras as well. Different strokes for different folks, I suppose!A bit confused by the 24mm f/2.8 EF-S pancake prime. I use the 24mm f/2.8 IS on my SL1 and it is tiny.I can understand your arguments, but ...
I guess if you're really interested in saving a minute amount of weight & size, a little bit of money, and trade IS for STM it might be worth it. But I can't see it myself.
thinking about an 24mm f/2.8 EF-S pancake at the price and performance of the 40mm pancake I think the 24mm f/2.8 IS it a totally different league and nothing to compare. your thoughts?
(of course if you already have the 24mm f/2.8 IS the 24mm pancake is not interesting)
