The same improvements available for APS-C are also there for FF to improve picture quality.High end apcs cameras nowadays are almost nearing the picture quality of FF cameras. But FF still trumps it on ISO sensitivity, DR, resolution, and focal length effectiveness.
I must be one of the only ones who care about it, but for me the big advantage of FF is way cheaper glass. Thanks to the larger sensor the glass doesn't have to be as sharp for the same resolution. There is also so much old, forgotten glass which still performs well. The Canon 100-300 f5.6l and 50-200 f3.5-4.5l have horrible AF and look nasty, but feature really high end glass (1 fluorite element for the former, 2 for the latter) and cost like 300$ used now. The latter is super rare though. Fluorite glass is only found in the most expensive telephoto lenses (think 500mm f2.8) and is the best glass for low CA. Telephoto designs induce CA hence the requirement for special glass in all high end telephoto lenses.
Canon's 35mm f2 with IS is 600$ and they have patented a 50mm 1.8 with IS which will probably also cost a fair bit more than the 50mm 1.8.Insane to me that they can get way with such high prices for 35mm and 50mm 1.8s.
I'd say this is looking more and more likely. It will be interesting to see what a fractured lineup like that will look like and my dream is either Nikon or Canon will jump on board. Every Canon EF-lens transmits its focal length (for the AF system) and would work with IBIS.I'm waiting for Sony to put IBIS in lower end model, then a wide 2.8 will be all I need instead of paying an arm and a leg for a wide 1.8 or 1.4.
My XM-1 with 27mm 2.8 would be a perfectly, inexpensive, casual camera if only it had IBIS.
Cropping will also not give you the same DOF for the same reason smaller sensors have more DOF (they use wider lenses for the same perspective). High ISO will also look worse for obvious reasons.So, I'm a little torn.
On one hand, I could save up for the official Sony 35mm (which it seems has a really nice aperture and macro), but I'm wondering this: Can cropping more or less replace having a variance in men's focal lengths?
What I mean is, if I took a photo with a 50mm, and then took a photo with a 35mm, and cropped the 35mm, could I end up with two nearly identical photos? I know that the 50mm would end up having better detail resolution when zoomed up close, but if I'm mainly taking 1920x1080 masters, then is there any particular advantage to having both? Or can cropping + a 35mm take care of 90% of my needs, short of telephoto?
Other than that and sharpness it'd be identical. The 35mm days really made people believe focal length had some special connection to field of view
