IT IS NOT TECHNICAL AT ALL, PUT THE LENS ON YOUR CAMERA AND SEE FOR YOURSELF.

The "C" size will be a better size for long lens person and a "FULL" will give you a wide angle advantage. That said, If you are looking a long term approach and just getting started I would look toward a C size camera as they are less expensive and consider buying full frame lenses as they will work in both FULL and C size cameras. A 100mm lens is 100mm in a full frame camera but will be 150mm in a Nikon or 160mm in a Canon, so you gain length with a "C" camera but a 18mm wide lens is a 27MM with a "C" so you need to go wider with a "C" for a 17mm shot. A 17mm shot will need a 10mm lens on a "C" camera

I think I remember that a Canon EFs lens extends further back into the camera body so if it is forced onto a Canon FF body it will damage the inside of that body. I've been known to be wrong before. Just ask my wife . . . .

Hi Ed! If you have ever paid attention to “supercars”, you did see that the manufacturers only used very sticky summer tires. None came with all season tires for a very good reason. Same with camera gear. You need very good glass. Also, best results come from a solid tripod. Any mistake and you will see them in the photos. What ever you do, have fun doing it.

Yes that is correct although you really can't force it on and get it to mount, however non Canon crop sensor lenses use a standard EF mount and can be mounted on full frame Canons.

It will work nicely on some of the Nikon full frame cameras and can even improve the frame rate (D810). I'm looking forward to finding how DX will perform on the D850 compared to the D500 as the pixel count will be approximately the same. I expect the noise to be less.

Still waiting for my 850.

You are correct as regards Canon EF-S lenses, although it can be complicated. This does not typically apply to third party lenses designed for APS-C cameras.

The 5dsr has an APS-C mode. If using an EF mount will give you a decent picture, just won't use the full sensor with all the quality it is capable of.

I have read through this question and all the discussion about lenses that will fit or won't fit and what the results might look like. But no one has pointed out the reduction in resolution. I believe by using an APS-C lens on a full frame camera will result in only about 40 percent of the resolution of the FF sensor or thereabouts. That in and of itself is not bad but it should be recognized.

The effect varies by lens. As Robert Jerl shows with his without hood shots, the Canon APS-C 10-24 works quite well when zoomed tighter than the full 10mm -- just do a little post-cropping or you can use the healing brush on the vignetted corners. With Sony their 10-18mm APS-C zoom can be used on their full frame cameras in the same way. I would let the camera vignette rather than set it not to do so. Then you can choose your cropping later in your editing. If you do it in camera you are limited to the camera's aspect ratio (usually 3:2). Doing the crops in editing you can use any ratio you want. Many of shots lend themselves to nice square prints -- sometimes even the circle made by the vignetting also looks nice.

In addition, when you travel of are doing a lot of walking, the much lighter APS-C lenses will make you far more comfortable.

I'm having fun today with my 5DSR and Tamron 150-600 sitting in the woods, waiting for a big deer to come by. Have seen 2 does and a fawn so far. They all came within 15 feet of the tent I am in. They did not seem to detect me.

That's great, but in what way does that have anything to do with the topic?

I shoot a Nikon DX 35mm full frame on my D600, I like the look with darker corners. The image circle smooths out as I stop down the lens. It's like shooting a six inch Dagor on an 8x10 view camera.
