ownership:I own this lens
compared to:Minolta 50mm f2.8 macro
Vivitar 100 mm f3.5 (cosina) macro
price paid:$199.00 USD new
positive:Light,small, reasonably fast focus. Uses 49mm filters (same as Minolta lenses).
negative:Plastic lens mount, loud AF. DMF on A-700 will not work
comment:Very small light weight lens. gives the equivalent focal (field of view) length of a 45mm on an APS-C sensor.

My copy seems to have no back or front focus in my quick and dirty test. AF seems fairly fast and it locks quickly. SAM focus motor would be ok if it were significantly less noisy than screw drive, but there really is no advantage. It may actually be noisier. This lens is so light weight that on my A-700 with grip the camera will not tip over with the lens on.

Be careful when getting really close, if you shoot on an angle the lens bottom will touch your subject

I'm not sure if the plastic lens mount is really a concern on such a small light lens


The more I use this lens the more I like it. I have used with multiple off camera flash units and doing "product" style photography it really shines. Images are sharp and crisp. A real sleeper
