Hi guys, 

Having a lot of trouble with the Sony A7rii. I decided to buy one (used) a couple of months ago and bought a Used Sony FE 3.5-5.6 28-70mm OSS. When testing it out I found that the images seemed weirdly noisy and blurred despite shooting on RAW, with low ISO, high aperture, a shutter speed above 1/125th and on a tripod. After discussing with the camera shop I thought it was the lens (lens aberration) so decided to get the Sony FE 50mm 1.8 new from the same shop I got the camera. 

When I got it there was a definite improvement but there were still problems with noise and handling contrast and depth when it was a landscape. I shot RAW and JPEG and I was completely baffled. So I thought it was the sensor of the camera which was wrong and returned it. 

I have now bought another used one from eBay from someone who worked at Jessops the camera shop. And I am having the same problem with the 28-70mm lens. (I have returned the new Sony FE 50mm lens). 

Firstly, should I buy a new lens and give it a go-to see. 

More importantly, however, what am I doing wrong??? I'm a recent photo graduate so have a fair amount of experience and I'm stumped. I was really looking forward to using this camera and this ordeal is now over a month-long!

(I've bought used because I'm a graduate and the price of a new one is £££)

Thanks!
