50mm lens issues
Recently I decided to have a crack at the 50mm macro, given a desire to start doing a bit of portraiture, and having always had a bit of an interest in entering the macro world.
As a macro lens, I am already having a lot of fun playing with depth of field and all that. Its taking some getting used to, and it really is a totally different style of photography. So I'm really enjoying that aspect.
However, I went out with a nephew and niece recently to have a bit of a play around with the portraiture aspect, and found that a very large number of my images were out of focus. I was shooting almost exclusively at f2, so depth of field wouldn't have been great. However, I was shooting from a range of a couple of metres or more. We're talking full body length portraits, or half body with plenty of space above them. Basically everything out of that subject distance was out slightly.
I've had a play around with it at home, and it appears to be a front-focussing issue. When I stop down to f5.6, its sharp. However, I attribute this more to the f11-like depth of field than anything else. Exact same setup and at f2 or 2.8, its soft, and f4 shows a hint of softening.
My thoughts are that the AF on the camera (E-520) is out, and I've just never noticed because I've only used kit lenses previously. Their depth of field is (relatively) extensive. That would explain why it's sharp enough at kit lens aperture/focal length combos. But then everything is pin sharp at close range (i.e. under 1m with the 50mm) anyway.
Olympus Au has recommended I send them the camera and lens. However I don't really want to be without either for the next few weeks, so just wanted to get some input on if anyone's had similar issues, and how it was resolved? I'm also open to any opinions on what people suspect might be the issue? If it's a camera issue, I may be able to get it sorted out by a repairer...
I'm pretty disappointed with the issues - the lens is otherwise an absolute cracker! Highlight bokeh is stunning, and focus is no slower than the kit lens at portrait distance. If only it hit focus!
