With respect, that's just your belief, you've bought a new camera and you're determined to justify the expense by asserting it'll drive you to improve.
If you want to statistically examine the likelihood of that outcome, look at the people who spend most of their time in the gear buying/selling/discussion sections and see how little those folk talk about making photographs.
Hundreds of cameras are bought every year by people on this forum, and there's no evidence to suggest that anyone's photography has improved simply due to gear.
I don't think there's much doubt that we could all do with a little stimulation now and then, to keep pushing on and try new things. That's what improves our photography.
That stimulation comes in many forms, and buying a new piece of kit is certainly high on the list. It doesn't have to be a new full-frame camera though! A new lens, flash gun, or even something quite humble like a few filters or extensions tubes can do the trick. Or it can be an event like a baby, a holiday, or just a day out to the zoo, an airshow, nature reserve, whatever!
lenses are more expensive I belive
Why do people keep talking about print sizes?I don't know how true this is if you're a Canon or a Nikon shooter as their APS-C lens ranges seem to be a little lacking in some areas and some people seem to end up using FF lenses on APS-C cameras. Actually when I had my 20D I had twelve AF lenses at one time or another and only four were APS-C lenses and when my little kit bag finally stabilised I had eight lenses and only one was APS-C and eventually that went and all my remaining lenses were FF up until I sold the 20D.
So, if you use an APS-C DSLR you may find that the lenses you want are FF anyway... Just something to think about.
As to the question of what's best... if printing massive or using stratospheric ISO's I think that bigger is probably better but if not printing the size of a barn and if using only ISO 100 to something reasonable these days, say 25,000then maybe anything from MFT and upwards will be fine
Many people these days don't print and only view on screen and if doing that a 2000 pixel wide image might be easily enough.
Why do people keep talking about print sizes?
I can see a huge difference at lowly screen size (dynamic range, shadow detail and noiseless clarity of the shadow detail, sharpness etc even at ISO 100) but that's been discussed already.
For huge print sizes massive MP sensors have the advantage, APS-C cameras are definitely not lacking there so I can't see that as an advantage. Of course with FF you'll get better quality large prints, as you do with smaller prints, so that's completely relative.
Nope, images I've taken on APS-C and full frame.Because print or display size matters?
If you can see huge differences at screen sizes maybe you are looking at crap images?
Nope, images I've taken on APS-C and full frame.
Are these crap? I don't know, but it's relative as I've taken both and can compare the technical merits directly (as others can).
The fact is, full frame sensors are better on pretty much every level. Fact.
It's up to the consumer (or business) if the added cost is worth it for them.
Have you ever compared the 17-55 IS to the 17-40L?With the Canon 17-40/4 L you pay a lot of money but you get superior glass, a lens that will work very happily with crop and will work with FF if you decide to, with the EF-S 17-55/2.8 IS you get longer reach and a faster lens but with poorer quality glass and a lens that will only work with crop.
