    Some 300mm f5.5 Asanuma samples

    That was a very long time ago! I replaced that lens with an old Sigma APO f5.6 400mm. Much better results since then. I've no idea how much better they could be if I bought a decent modern lens.

    Some 300mm f5.5 Asanuma samples

    Very true about thinking you're in focus when you aren't. I've been doing some focusing tests to check my accuracy. I set up on a tripod, with an angled tape measure as a target, and focused with live view zoomed to 10x. I stuck a bit of masking tape on the lens barrel and marked the position...

    Some 300mm f5.5 Asanuma samples

    The Konica bayonet fits 4/3? I never knew that. I assume it must be deliberate, not a fluke. I read though that some spacers and slight modifications are required. Funny that they'd copy another mount, but change the spacing. I tried a baffle in my 300mm lens, I couldn't see any difference...

    Some 300mm f5.5 Asanuma samples

    Thanks for offering that, very kind of you. I have instead decided to try a 400mm lens, the equivalent of adding a 1.33 teleconverter, except there will be no light loss. I have a Sigma APO 400mm f5.6 on the way in the post, and also today stumbled on a Tokina made OM Vivitar 400mm f5.6...

    Some 300mm f5.5 Asanuma samples

    Which camera are you using, and which AF mode? How do you tell when it's locked on? Surely you'd have the same trouble I would have telling whether I've focused on the bird accurately.

    Some 300mm f5.5 Asanuma samples

    I've spent a bit of time enhancing the White-plumed Honeyeater. I've selectively sharpened it and adjusted the levels for more contrast. Probably a bit of a clumsy first attempt (looks a bit suss that the branch it's sitting on is blurry). Opinions please, even harsh ones.

    Some 300mm f5.5 Asanuma samples

    What causes poor contrast, and what do I look for in the image to determine how good the contrast is? Can someone show me an example of an image with good contrast?

    Some 300mm f5.5 Asanuma samples

    "Muscle memory", interesting concept, but I think I can understand what you mean. Swapping between binoculars and camera has been causing some delays with getting my eye ready to focus, but this seems to be reducing with practice. I will try practising like you suggest, it can only help...

    Some 300mm f5.5 Asanuma samples

    That's cool, I'm a dpreview forum veteran, and expect no mercy. I asked for it with my comment about this being a good way to get into bird photography. (It is for me, but wouldn't be for someone with higher standards.) While it would be nice to have something to compare to, unless the...

    Some 300mm f5.5 Asanuma samples

    Yes, they're 100%. So what should I be doing to display them in a way that lets people evaluate the results better? True, I have to focus bracket to be sure of some well focused results and, as I said, my S3 often did better. But I found that a very large percentage of my shots were behind...

    Some 300mm f5.5 Asanuma samples

    It's nice to be able to put the results into perspective, that's what I put them on display for, but can you be more specific? Too soft? Some other fault? To my eyes, the images I see when I click on those thumbnails are way too soft. But I'd never normally view them that big, maybe half or a...

    Some 300mm f5.5 Asanuma samples

    In a previous thread someone requested some sample shots from my E-520 with 300mm Asanuma manual focus lens. Here are a few, and apologies if I haven't uploaded them correctly. I've cropped them to be no more than 900 wide, no resizing, and I don't think I've enhanced them at all. Now that I...
