Philmophlegm bought me some lenses for my birthday, and because they were not a surprise, I got to try them out a bit early. They are all old manual lenses which probably came off old film SLRs, and I am using them with an adaptor on my NEX 3. I had no idea how well this would work - I'm experimenting! But old film lenses are not expensive, so I have got three Pentax fit lenses to play with:
a Pentax 50mm 1:1.7
a Pentax 28mm 1:2.8 (came with a case which had a receipt from 1988 in it!)
a Tokina 70-210mm, 1.4-5.6 zoom lens
All of these were taken with the 50mm, which I am liking a LOT. Tomorrow I shall play with the zoom lens I think - it's a bit big and heavy for the teeny NEX body really, but not unmanageably so. Manual focussing is teaching me a lot about focus and aperture.
