I really dont like tabs. It's true - some lenses do need them, but i still dont like them. Most of my lenses dont have them. And the ones that do - are the lenses that I really, really like - otherwise i wouldnt put up with them. I even sold some lenses that I liked ONLY because I just couldnt deal withthe tab - like Minolta Rokkor 40/2. At the moment I only have 3 lenses that have tabs - and only use one on regular bases, just because it's so good.
