After using my E520 with a manual focus Sigma APO 400/f5.6 since I bought it several years ago, I've bought a used 70-300mm lens and I've got a few questions.
- How do you hold it? Assuming one shouldn't be supporting it by the zoom or focus rings, or the moving outer barrel, there's not much left to hold.
- What's the best focus mode? I've got it set to SAF+MF so I can override it when there's vegetation in the way. I couldn't work out CAF+MF. As soon as I stop turning the focus ring, it AFs again.
- The focus ring is slow and gives no feedback. Is it safe to just turn the barrel to focus mechanically?
I still have to do some proper tests, but so far I'm disappointed with the image quality. Seems very flarey to me. I thought it might rival the Sigma despite the shorter focal length, because the design is decades newer, and the Sigma has haze on an inner element that would make it unsellable except sight unseen on eBay to suckers like me. Could it be that I've bought a faulty one?
