No user reviews at dyxum reporting broken Sigmas Don?
I didn't have to look far too find these.http://www.dyxum.com/reviews/lenses/rev ... IDLens=221
I bought this lens new from OneStop Digital on recommendation. Good choice in terms of lens and company used. Definately one for the camera bag. Excellent value for money lens. Great Bokeh. works fine on A100. My copy stripped it's AF gears withion 2 hours of first use on A700.
To look at and handle the lens is great, the lens hood attaches easily and quickly, images are clean, clear and sharp and IMHO the lens compare very well against the Alpha's kit lens, colours are excellent, on the down side, i did find it a bit slow at focussing (hunting issues) and a bit noisey, for me though the worst thing is the build quality, the zoom barrel on mine is stiff between 200 & 300mm and after trying to ease the play, (by simply rotating the zoom) the lens broke, If you can get one that's not stiff you'll have a good lens, if on the other hand you get a sticky one; be careful
Nice upgrade from the DL Macro I owned. It's a good lens for the money and is very capable.
This update was long overdue. I have changed my opinion of this lens, I am downgrading the build rating to a 2 now. The Scale Ring has failed/ broke three times since my intial purchase. I am not a tech guy but, the scale ring is part of the AF system of the lens. it mates up with the AF Drive Motor of the camera. So when it fails there is no AF operation, just a very bad sounding humming noise. Sigma has repaired this lens twice. It is currently (8/27/08) in their service dept. for evaluation.
I have made it clear to Sigma I have no interest or confidence in this lens now. Sigma does not offer refunds, so the best I can do at this point is a new copy of this lens. Which I believe will lead me back to the same place I am at now. I say that because to my knowledge Sigma has not done anything to upgrade or correct the scale ring issue in its current production lines.
So I say buyer beware if you are mating this lens to a Sony Alpha body. You may get a copy that is reliable but then again you may not!
beautiful lens for the pricing. Was my first lens together with the kit. pefect combo to start with, not as cost worthy and good learning. Macro is very useful, but don't expect 100 2.8 levels
Update: AF is malfunctioning, seems there is a geartooth missing.
Brought it to Sigma BeNeLux, now we wait! ( 11-03-08 )
Got it back two weeks ago from Sigma Benelux (4-4-08), what a service from these guys, repaired it under warranty, although it was 5 outside the warranty period. Good service!
