Summary: Should have been a 5 star lens, if not for the fact that the AF broke in a week with very light use! I only tested the AF a few times before it stopped working all of a sudden. The lens itself produces great macro shots. I am not a weight lifter so I use it on a tripod. MF works fantastically well. But still, AF broke in a week is a very bad sign. I sent it to Tamron and it stayed there for 2.5 months now and they are still working on it.
Summary: I use this lens to shoot flowers, insects etc. I really enjoy the shooting with it. I will say it is very worthy the price. Advantage: 1. Good Price 2. Sharp 3. Color is fantastic 4. Easy to switch between AF and MF 5. The lens looks STRONG with the lens hood!! Disadvantage: 1. AF is a little bit slow. 2. No Full/Limit switch, which SP 90 macro has.
Summary: I have captured some really great images with this lens. I believe I will have it for a very long time. The Macros come out so beautiful. The only thing I don't like when doing Macros in that at very close range, the Macros tend to blur a bit. Other than that I love this lens. I would buy it again and again. Thanks Tamron!
Summary: Having spent a year with a 90mm macro trying to shoot insects that were no longer there because I was too close for their comfort it was a great relief to find that the extra working distance this lens gives you does indeed give you many more opportunities to get decent shots. It is as sharp(very) as the Tamron 90mm and has a great bokeh. i had to sell a very nice guitar to get this lens and have no regrets in doing so.
Excerpt: Kevyt ja hyvin piirtävä makroputki esim. hyönteisten kuvaamiseen. Kulkee helposti mukana keveytensä takia, vaikka Sigman 150/2.8 onkin vähän pienempi. Kontrasti ei aina ole paras mahdollinen - varsinkaan isolla aukolla vastavalossa - mutta paranee jälkikäsittelyssä helposti. Makrohommissa tuosta ei ole haittaa. Bokeh on valopisteillä vähän kulmikas - sulkimen lamellien määrä ja muoto voisi olla parempikin. Runko on muovia, mutta kestävää sellaista.
Pros: Terävä kuva, Kevyt, Hyvä tuntuma käsintarkennuksessa
