I was thinking I could adapt an alpha telephoto lens to my 5n with the proper adapter, but I think I just remembered that the alpha lenses do NOT have IS, making long telephotos nearly useless. Does anyone know if any alpha telephoto zooms have IS? Maybe even from Sigma or Tamron or something?
Whatever did we do before IS? Just make sure your shutter speed is at least the same as the focal length.
Alpha bodies have in-body stabilization, so naturally their lenses won't. You kinda really need to shoot with a tripod for tele above 200mm anyway.
I don't use tripod for long lenses, only for macro or portrait "sitting". Use fence post, chair, door/window frame, rock, knee, etc. No IS needed. In fact, with the above methods, IS will actually soften the image many times. With practice, the long lenses are very easily stabilized with very small camera bodies. For instance, the Vivitar 70-210mm Series, is a big heavy lens, that I use on the E-p2 and others, free hand. And I have old shaky hands. So I have to use the "prop" method with all my lenses. Becomes second nature after a while, unless you/I am willing to settle for blurry pictures, which I am not.
OSS isn't everything. I plan to complete my setup with these new CZ lenses announced, and no single one of these has OSS. The effect is the same as on telephoto lenses - you just have to use shorter shutter speeds - and a tripod, when the lights get dim.
