Some more budget photography

Not really sure what you mean by that? Surely a lens will work or not! What's to 'trust'. I have used a good selection of old lenses now, and they are either sharp or not, sometimes they have an odd quirk, like a need to be stopped down, or some chromatic aberration, but they're well known issues with old lenses, and can often be worked around.

I only have the Mk1 40-150, which doesn't focus that close, although I now have a Sigma 55-200, which is a little better, but not quite as sharp. I didn't know the ED version went that close - is that at 150mm, or only at 40mm?

In my experience, sometimes you can get an old 'legacy' lens that performs equally as well as the newer digital lenses.

Thanks.
