  • Hi, I'd recommend the 15-85mm for a crop camera, just watch out for flare at 15mm. Martyn
  • I think it would be a pity to sell the 35mm f/2 IS, especially when used on a 6D. I have both and find the IS useful (on the 35mm) useful for video and for very low light shots. The 40mm f/2.8 is ...
  • The subject was a flower against a white wall so the purple fringing was clear even towards the centre of the frame. Even so, this is nowhere near as bad as purple fringing on a Panasonic 25mm f/1.4.

  • I had the 50mm f/1.4 and replaced it with a 35mm f/2 IS. Unfortunately, the 50mm f/1.4 suffers from terrible softness, purple fringing and lack of contrast until f/2.2. It's fine for narrower ...

  • I'd pick the 24-70 f/4L. I've owned the 24-105 which was soft between 90-105 and distortion was high at 24mm. I cannot comment on the Tamron but there has been reports of build quality issues. The ...
  • I find the 24-70 difficult to use in macro mode as f/11 is needed to reduce RSA at near minimum focusing distance. I find this problem is not so bad when using LiveView so I wonder if phase ...
