    Tamron 90mm f/2.8 reviews

    SP 90mm f/2.8 Di Macro Autofocus Lens for Pentax AF is rated 4.5 out of 5 by 34.
    Rated 5 out of 5 by from Wonderful lens I've used the lens for both macro (obviously) and portrait work on my K10D, and it's been great for both. I've read other reviews that call this lens the portrait macro and its creamy smooth bokeh doesn't disappoint in this regard. Construction is high quality, though still plastic. The manual focus ring is very smooth. In fact, my only complaint with the lens is that the quick shift focus mechanism doesn't override the camera's settings, which means you have to both pull the focus ring back AND switch the camera to MF in order to manually focus. Not usually a big deal, but I have missed a few shots because of that extra step.

    Rated 4 out of 5 by from All around decent lens The lens is sharp, produces great image quality and is a worthy alternative to the Pentax-made equivalent. The bokeh produced with this lens is fantastic and I've not seen any issues thus far with chromatic aberrations or purple fringing. Its only downside is the somewhat slow, noisy autofocus which tends to hunt, though this problem is mitigated a bit by the focus limiter. Another issue that the length of the lens does extend significantly the closer you focus in on something, however this is common among lenses in this class so it can't be said to be an issue with this lens in particular. There do exist macro lenses which don't have this problem however.

    Rated 4 out of 5 by from Tack-sharp I'm using the Tamron 90 for general closeup and macro work, and finding the experience very pleasant. The automatic focus sometimes hunts a great deal and is somewhat noisy, but since I use manual focusing for more precise macro work, that doesn't matter. As a general short telephoto (on an APS-C sensor it's the equivalent of a 135mm lens on a 35mm film camera) it's also excellent. There is a slight softness at f2.8 but this disappears by f4. Its plastic construction keeps the lens lightweight. It does not feel cheap at all. I have no regrets about purchasing this lens.

    Rated 4 out of 5 by from Great value This is my first dedicated macro lens, and makes me wonder why I took so long to buy one. Used with Pentax K10d / K7, the output is far better than I expected.

    Rated 5 out of 5 by from Sharp and accurate focus It is sharp and focus speed is good. Changing between auto and manual focus is not as bad as some say. Mine had a rattling sound when moved and I replaced it, but there are many reviews online that say about this rattling sound and say it is normal!?! . Front element is recessed a lot so I do not think hood is needed at all. It comes with pouch. It is not stabilized so Pentax and Sony cameras have the advantage with this lens.

    Rated 5 out of 5 by from This thing is great! I did ALOT of research before buying a macro lens. SOOO glad I bought this one. This first shots I took with this lens where so sharp. F8 to F13 are really good. And the price is great compared to other lenes. Plus there's a rebate. It's not heavy are hard to use. It does search alot but I found it easy to manual focus with my K10. I did not think it would be this sharp and the out of focus areas (forgot the name) are so smooth. You could pay alot more but you don't need to. I think between the quality and price it deserves five stars.

    Rated 4 out of 5 by from Solid performer This Tamron macro is a classic and has performance to back it up. It is sharp wide open and sharpness does not drop until f/16. Relative to the Pentax 100 f/3.5 macro, this Tamron is a tank. Besides being a 1;1 macro, it can also be a portrait lens. The fast f/2.8 produces a nice diffused background. I wish it has SDM or equivalent. Focus speed was not slow but not fast either. The lens extends a lot and hence smaller effective aperture at high magnifications, so an IF design would be nice. I eventually returned the lens not because it is poor. Not at all. The improvement over the Pentax 100 f/3.5 was not significant enough to justify replacing it. I have a list of wants in the pipeline, this Tamron was at the top of the list.

    Rated 4 out of 5 by from Nice light lens I bought this lens for portraits and macro photography. I used it to take available light pictures at a conference where it behaved wonderfully. I think that compared to the older Pentax FA 2.8/100mm this lens is much lighter and seems to have at least comparable quality. The one thing that is not so nice is that the lens hood is not quite so easy to attach, especially in the reverse transport position. There Pentax lens hoods are much better. I use this lens a lot.
