Bicycle Bottle Holders
For the price they are OK but you need to add extra crimps where the cage connects to the mounting plate. Otherwise they become loose in short order. Once this is done they work OK, I used a machinist punch to add extra crimps.. Lay it on a metal surface and pound in the crimps with a hammer and punch. You may have to repaint after.

Quantaray 28-300mm F3.8-6.3 Autofocus on Sony A100/D5
1 von 1 finden das hilfreich This is the second lense of this type I have bought. Very fast in autofocusing on a Sony A100, extremely fast on the Minolta D5. Some of these have had problems focusing with Minolta and Sony Digital cameras. Contact the factory as they will correct this problem if you send it back. Excellent depth of field at distance but becarefull if you use in close, will defocus background and in some cases that is OK but if you want it to not do that the play around with the F stop and exposure and it will work out OK. Good lense for wildlife, as overall focus is quick on either camera. With the antishake I have been able to pull of offhand shots with good resolution. but that is me, maybe you will be better or worse, try it.

Title good and accurate, all the info I need is there
I wanted a true wide angle lens for my Sony A100 SLR digital camera. This lens has been described as the best wide angle lens on the market today.
