  • 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.
  • Replied in Lens to sharp
    I don't think the concept of excessive sharpness or excessive lines per inch resolution exists per se, but a soft focus 100mm lens may be a more suitable alternative to a very sharp 100mm macro if ...
  • 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've had both and the 35L has uncorrectable purple fringing towards the centre of the frame at f/1.4, but does produce better blurred backgrounds. The cheaper f/2 is the sharpest lens I own and ...
  • 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 ...
  • I owned a 24-105 f/4L on a 40D a few years ago and eventually sold it because of distortion at 24mm (38mm on a crop body) and indifferent sharpness from 80mm-105mm. The 70-300L would be worth ...
  • I'm not happy with the 24-70 f/4L (inconsistent focusing and residual spherical aberration) so I'd suggest renting the f/2.8 version first or try the Tamron. I currently have a 6D with 40mm, zoom ...
  • I had the 70-300mm DO IS USM for about 6 months and sold it due to halation around highlights. This was particularly noticeable in out of focus areas. The 250-300mm range was quite soft even on a ...
  • Hi, I returned an E-M1 due to a serious lock up and noticed the quality of the paint finish was inconsistent. Most pro cameras don't have paint on the flash hot shoe so why Olympus decided to do ...
