Have you tried your camera with a different lens? Can you rule out lens problems? All the best, Armando

Richard, it looks very sharp even though it is a crop. Are you happy with the lens, especially image quality? Thanks, Armando

If the IS unit is defective, then AF will be off in certain occasions. It does not matter for AFMA, but it is essential to rule out IS malfunction. I do use a tripod for AFMA. Thanks, Armando

Thanks for your reply. I can be blind sometimes, so I decided to ask here. I agree that this should be included in the EXIF. I was testing my lens with IS on and off, but was not careful to write ...

Helo! I a trying to calibrate the AF on my 100-400 II lens, paired with a 7D-II. I am testing the lens hand-held with IS on and then off. However, I cannot find any IS info on the exif info, as I ...

Tazz93, I agree with 1Dx4me that your shots are amazing on flickr. I just followed you.

Thanks for sharing all these tips. Did you file a police report? Was your camera found? Apparently you indicate that your camera was stolen by a TSA person. all the best with your new 1DXII Armando

Beautiful! Single exposure? HDR applied? Great picture!

Copy 1 of the lens seems to be noticeably sharper than copy 2, or is it just my eyes? Armando

Great shots. Bring back memories from flamboyants in my native Cuba Armando

Did you get money back after the trade? 6DII + 70-200 2.8 II are worth more than the lens you got. Armando

Minimum Focus Distance in the 85 1.8 will be enough to do headshots. If you want to get closer than that, then you will run into problems. I think you should give it a try; it focuses better than ...

I agree it is fantastic for the price.  Another drawback for me, in addition to CA, is a not-so-great minimum focus distance. I can get closer, and therefore achieve same or better magnification, ...

Great samples. Keep posting them! Armando

Thank you all for your help. As it turns out, it was not the sensor but the lens. I mounted the same lens on my 5D-III, and the same darker circular area shows on the same spot of the picture. I ...

You got the location of the bigger circular marks this time, Ken60. As I said in my original post, this camera is still within its 14days when returns/exchanges are possible, and therefore also ...

SalmoTrutta, you  might have hit the nail on the head. That illustration you posted here (your picture) matches the shape of the darker circle I see on my three pictures posted above. It might be ...

You got it right, Mako2011. I am referring to the larger dark circular areas. Another poster suggested it might be dust on the rear element of the lens, not on the sensor. I will investigate that ...

I just acquired a refurbished 6D Mark II from Canon USA. (A second 6DII). I see something weird on the sensor, and I wonder what it is and if it will affect some images.  Can you help me out? see ...

Hi, gavin, what specific model of the peak design are you referring to? Thanks, Armando
