I would like some input on full frame cameras. Thanks
Pro: In some situations and for some purposes, a full frame camera can produce higher quality images.
Con: A full frame camera costs more. The lenses it requires are bigger, heavier and generally more expensive, too.
Most photographers don't really need full frame cameras, just think they do because of all the hype.
I'd also wager that many who use FF don't actually get any real benefit from them.
In fact, yesterday I was shooting a sporting event where another photographer was using a FF camera that quite possibly was one the worst possible choices for the situation.
I know from personal experience that her setup is a poor choice for the purpose. We were shooting an amateur equestrian event and she was using a FF Canon 5D Mark II (21MP) fitted with a Canon EF 70-200mm f/2.8L IS USM and a Canon 2X II teleconverter. I was using Canon APS-C 7D Mark II cameras (20MP) with EF 70-200mm f/4L IS USM on one and an EF 100-400mm L IS USM II on the other.
The 5DII (which I also have owned for many years and use for other purposes such as portraits and macro) cost her at least 50% more than what one of my cameras cost me, has a far more primitive, slower, poorer tracking AF system (15 points with three "cross type" versus 65 points, all "cross type" in my camera), shoots at 5 frames per second max (versus 10 fps w/my camera), and has a loud shutter that I've seen cause high-strung, inexperienced horses to "go vertical" and dump their riders.
I also have copies of the exact same lens and teleconverter she was using... A combo that I've tested and make a point of never using together due unacceptable deterioration of image quality. Her effective 140-400mm f/5.6 combination (70-200mm + 2X) is also about the same size, weight and cost as the far sharper, faster focusing 100-400mm I was using. For that matter, on an APS-C camera with it's "free 1.6X teleconverter effect" she wouldn't need the image-quality-robbing 2X on that 70-200mm. The lens alone might give more than adequate reach on APS-C. Or, if needed, could be used with a weaker 1.4X teleconverter which does much less "harm" to image quality. Or, on an APS-C cameras a less expensive 70-300mm might serve instead, giving better image quality, higher performance and greater effective reach. The f/4 version of the 70-200mm I was using is about 2/3 the size and weight of the f/2.8 version she was using, too. f/2.8 certainly isn't needed outdoors and can even be a problem, with too shallow depth of field. Besides, by the time a 2X is added to the lens, it's an effective f/5.6. Guess what aperture I'm using with both my lenses!
So.... she spent more to carry around bigger, heavier gear that's slower focusing, lower performance and certain to give poorer results... and might even cause accidents if she isn't careful. She has essentially taken three excellent products that are the wrong things for the purpose in the first place and is now using them together in a manner that's certain to make for lower quality results. Oh well!
"Full frame" certainly has it's uses... But it isn't the be-all, end-all that some people claim it to be. The vast majority of DSLR buyers don't need FF... And I'd bet that a lot of FF users don't really get any benefit from the larger format.
In a nutshell, if you can't articulate in detail WHY you need full frame... You really don't need full frame.
Or, another way of looking at it... If your images are falling short of your expectations with an APS-C camera, switching to full frame won't solve anything. In fact, it probably will just make for even bigger failures!
