Addict Posted September 12, 2015 Share Posted September 12, 2015 Full frame camera sensors have large pixels. If you do not take extra care of camera movement by using a tripod, mirror lock up and cable release as well as critical focus and best f stop your pixels will show softness at 100%. This gets worse as you go up in the pixel count with these 50 mpx cameras. i have had trouble with 5 and 6D canons with canon L lenses. CR and artifacts are also a problem as can dust. I have had better luck by downsizing to 4250 on the long side. Quite honestly with the prices we are getting now you would be better off shooting with a small walk around camera and give yourself a break. These cameras give quite acceptable results for most buyers using Alamy. If you dont like that then go with an aps-c camera which will be less frustrating when it comes to processing your images from hand held work.

Niels Quist Posted September 12, 2015 Share Posted September 12, 2015 I am also due for an update from Canon 5DII. I have decided to go for a mark III - just watching what happens to the prices.... I don't need the extra pixels and requirements for even better lenses. Would rather spend some money on a service on my 24-105L lens from 2007, which I like as a walk-around lens, but it will need some service soon (or a new one).

I have no difficulties with focus/sharpness on my Canon 5DII and L-lenses. Most times I don't use a tripod, and when I do, I get away with focused (sharp) images without locking the mirror, cable release, etc. CA is easily removed. Dust can be a problem. It helps a lot if you don't change lenses everywhere and not too often (two cameras - though a 7D with the tele for the time being, which gives advantages and disadvantages, but that is another story). Addict, I think your problems may have been workflow related or due to faulty equipment.. Niels Link to comment Share on other sites More sharing options...
hdh Posted November 19, 2015 Share Posted November 19, 2015 I have had no QC problems so far with the images I took with my 5DsR - but I always check at 100% before submitting. For the lenses I use the f4/11-24 and Sigma prime lenses 35, 50 and 85 mm all f1.4 respectively. I hardly ever use a tripod, but usually try to use exposure times of 3-4 times the focal length, ie 1/200 for the 50mm. The old rule exp time = focal length does not really hold with this camera and resolution. Although I shoot raw+jpg - I only used the camera generated jpg's so far. Also I uploaded soft pictures - but for artistic expression - and feared they may be rejected by QC, but were not, see example below. soft and accepted by QC: Tack Sharp, same subject Link to comment Share on other sites More sharing options...
