Just got a 5D2 and have a question.

I was just playing around taking some snapshots, and a lot of them turned out like this. Its a 50mm 1.8, and I am wondering if its vignetting?

I have used a 7D for some time and am wondering what the big differences a newbie should be aware of, if any when dealing with FF from crop.

ISO 100 F1.8 1/6400 50mm

Yup that appears to be vignetting! One of the big differences will be how much smaller the DOF field will be on the FF sensor. Be careful not to blow focus when shooting at a shallower DOF on the 5D Markii

Definitely some vignetting going on there. I had a 50mm 1.8 before going FF, and when I did it was doing that. Also like Nathan said, it is a lot easier to miss focus with the shallower depth of field.

The 50mm f/1.8II has 3 EV of vignetting when wide open. According to Photozone.de you need to stop down to f/4 for it to be unnoticeable.

You can correct it if you are using Photoshop (overcooked it a bit, but you get the point).

So is that caused by me or the lens?

Here are some more, with 85mm 1.8 and 150-500

Ahh, so I wouldnt of noticed it on crop because its centered out, in a way.

Yup. On a crop it would hardly be noticeable even wide open.

Have you tried turning on "peripheral illumination correction", for jpeg it's done in the camera, for raw you'll have to do it in Canon DPP before converting to jpeg.

... or in ACR/Lightroom or in Photoshop after converting to jpeg, TIF, etc. Lot's of ways to deal with vignetting that are essentially identical

Keep in mind that vignetting is actually a desirable (and normal) trait of lenses when wide open, so it's not like something is wrong with your camera.

Some lenses produce more vignetting than others and the cheap 50 is certainly the case here.

I would embrace the vignetting or stop down if you don't want to.

I'm with you. I like the slight bit of natural vignetting. It adds to the dreamy feeling of the shallow DOF shots you get wide open.

I agree. Nothing wrong with a bit of vignetting and it's certainly nothing to be concerned about since you can control the amount (+ or -) in post.
