Awesome, Lynn.I especially love #s 2 and 3. Make sure to post them on my Photographing Pets thread!
Can you explain to me exactly how it works for us to use older lenses? I know you need an adaptor and have to manually focus, but is there anything else to consider? Where to buy, EBay, Craigslist? I could use a fast zoom lens to shoot my son's indoor baseball practices this winter, and not sure if it would make sense to go this route. The new ones are quite expensive and I'm not sure it would be worth the investment since it's a fairly small segnent of what I shoot, though I will be sharing the pics with the rest of the team, and possibly the league. Maybe it makes sense to get the adaptor to have other inexpensive, vaired lens choices?
I guess I was lucky because I really didn't know what I was buying with this lens. But from reading on dpreview.com, the version of the lens I bought is supposed to be the best quality. It has the Made in Japan on it and a higher serial number.
It was cheap off of ebay, $17 including shipping. The adapter I got from Fotodiox for around $30. So I figure with a small investment, it's worth trying out.
So far I can't say I'm in love with it but I haven't really used it a lot. I didn't take it to Disney because from trying it out at home, I was getting a lot of blurry shots and I didn't want to miss anything there. You can see from my previous post that even though I thought Oscar was in focus, he really wasn't. On the occasions when I was shooting him and he moved, he was just a blur. And he doesn't move fast.

My next project with that lens is that I'm going to try and shoot a moving subject with the lens wide open and as fast a shutter speed as I can get. This may be a really stupid question, but I wonder how people shot action shots with a manual focus lens?

There's been a thread on dpreview about the best OM lenses. I checked a couple of them on ebay and they were in the hundreds of dollars range, so I think my next purchase will be the 70-300. I was really wanting it this morning. We woke up to about an inch of snow and there were two deer behind my house. I took a bunch of pics with the 40-150 but I haven't downloaded them yet.
I know you've mentioned that you have the 25mm. Do you like it? I haven't decided if that's one I want to get yet.
