Do you know if this would work with 6D and Sigma 10-20mm lens?

The reason I am asking is because this particular one is white one and when do google I dont see white but see black. I had a conversation with seller and as per seller it will work but wanted to see if its ok.

What are you trying to DO here? Turn a 10mm lens into a 15mm lens, expanding the center of the image circle to cover the FF sensor so you don't get that dark vignette? I guess that must be it.

Here's my gut feeling: you have a very nice sensor, just CROP. You'll get the exact same effect without introducing the variable of an inexpensive, less finely-engineered optical component into the image path. The 6D sensor, cropped to APS-C dimensions, is STILL better IQ than, say the 20D that was state of the art when I got it.

I have NO problem doing extreme crops on the 5D2, for what it's worth.

Thanks Robert! I tried yesterday with my 10-20mm but even if I go all the way up to 20mm I am still seeing vignetting. I understand I can crop the image and take vignetting out but wanted to see if there is any other way and not go with cropping thing!

I agree with Robert - much better to crop after the shot. I have the crop function on my D600 but I prefer to crop it afterwards :)
