  • 1Description

This Di lens is currently the most compact and lightest in the history of fast zoom lenses. Its compactness makes it look and feel like an ordinary standard zoom lens, yet provides the versatility that a fast constant maximum aperture offers and will definitely reshape photographic horizons.

Features like LD glass elements and Internal Focusing put this lens in the same category of professional lenses as much bigger and more expensive Tamron lenses.

LD glass elements reduces various aberrations while minimizing the fall-off of light at the corners
Features XR (extra refractive index) glass and efficient use of aspherical lenses

    Tamron 28-75mm f/2.8 reviews

    28-75mm f/2.8 XR Di Autofocus Lens for Pentax AF is rated 4.1 out of 5 by 30.
    Rated 5 out of 5 by from Much cheaper than four prime lenses I skipped over a 21mm f/3.2, a 40mm f/2.8, a 50mm f/1.4 and a 70mm f/2.4 to simply get this lens instead. If you've got the money and don't mind changing lenses often you could likely surpass the Tamron 28-75 f/2.8 in image quality with four primes (not withstanding shots missed while changing lenses). Personally, I DON'T have the money for four primes and I DO mind fumbling with lens changes due to both missed shots and dust exposure so a single zoom lens solution was the most practical for me. This lens lives up to it's reputation for sharpness and the DOF at f/2.8 is plenty shallow enough for me - I find that I don't need any less.

    Rated 4 out of 5 by from Follow up I have owned this lens for 7 months and have used it mostly to shoot indoor events. I highly recommend this lens. AF is accurate and pictures are sharp. I find the focal length range very useful. Surprisingly, the wide end is wide enough for much of my close-quarters indoor shooting. Also, it helps me avoid taking photos of people which have that distorted look that can happen with wider angle lenses. The only flaw in this lens is that the zoom ring action is not consistent throughout its adjustment range. For that reason, and because a previous copy of this lens was soft, I am giving it 4 out of 5 stars. This is a great lens!

    Rated 5 out of 5 by from Excellent price for outstanding lens I use this lens semi-professional and I am extremely happy with this price/quality combination. Constant 2.8 output across the whole zoom range, outstanding resolution and warm color rendition make this lens one of the best choices for Pentax users. I choose this model over Tamron 17-50/2.8 because I believe that next camera's generation will be full frame and I do not want to waste my money on something that will go away in couple years. Resolution of this lens is far better than Pentax's 16-50 /2.8 for half the price!!!! The build quality is very nice however we can't expect Canon's L or top Nikon workhorses here. Auto Focus on My Pentax K20d is fast ( Not fast enough for sport photography) precise but on a loud side which I do not really care for .Great everyday walk-around Lens that comes with 6 YEARS warranty!!!!! Bravo Tamron!!!!!

    Rated 4 out of 5 by from Works for me..... I had debated for months over which fast zoom lens to add to my kit for a general wedding/inside shooter. The Tammy won out over the similar Sigma and Tokina lenses in test's which I had looked over, so I made the purchase. Although I have heard tales of bad copies of this lens out there, mine was a beautiful little performer. However, - it broke at the mount under little duress as well as had developed in a very short time a bad case of lens creep. Hence my only awarding it with 4 stars. I will probably replace it with another of the same, but have been made to wonder whether I'd made the best choice in the 1st place for my uses. Sure did get some wicked nice portraits out of it while I had it tho! ;o) Recommended. With cautions.

    Rated 5 out of 5 by from Its reputation is true The reputation of this lens as a bit of a legend precedes it nearly everything I read about it is true. It is sharp, including surprisingly good performance at F2.8 which is important since speed is the main reason you buy a lens like this. And when stopped down to F4 or 5.6 it really is excellent. I find the focal length range (43-115 mm equivalent for a Pentax APS-C camera)to be extremely useful. I use it mainly for indoor music concerts, but it serves well as a general purpose indoors or outdoors lens, especially if you also carry a wide lens such as the DA Limited 21/3.2 or 15/4. I also own a Tamron 17-50/2.8 (a great 'standard' lens) but the 28-75 gets more use due to my need for the extra reach. I also like the bokeh, it autofocusses well, and the build quality, if not excellent, is pretty darn good. It feels good in the hand on both my K20 and my K01. Finally it is compact, incredibly so when compared with Nikon or Canon 24-70/2.8 lenses!

    Rated 4 out of 5 by from Great lens for the price This is an inexpensive, yet an excellent lens with constant f2.8. I bought this lens to use mostly at f2.8 for available low light situations. Not that optical quality is bad at f2.8, but it shines at f4.0 and above. If you want an inexpensive, normal to telephoto zoom lens just get this lens. The 4 star rather than 5 star rating is for the slightly lower optical quality at f2.8.

    Rated 4 out of 5 by from Awesome Portrait Lens on a Budget! For the price, this lens is Terrific! I needed a budget-minded portrait/medium light lens for my K-20D and this one hit the spot. It is clean, crisp and fast... and I didn't break the bank buying it. I recommend it to anyone with a DSLR looking for that portrait-range lens with enough speed to work indoors and enough range to work the crowd outdoors. I'm considering another one for my K-10D.

    Rated 5 out of 5 by from Great regardless of price! I really cannot fault this lens. I is a classic, period! It focuses faster than the Pentax kit lenses and certainly does a trick in near darkness where focusing is supposed to fail! It is capable of stunning color and sharply isolated portraits with a very neat bokeh. I have 2 K100d bodies, a K20, and a K-x, and unlike my other lenses, it does equally good on all four of them! The bright f/2.8 ratio makes this a winner indoors and also outside for depth of field control. There is some criticism here about its range. Nonsense! It reaches from an equivalent 42mm, a wide normal, to an equivalent 112mm, slight tele. Not everybody has a good eye for wide shots and I have always found that getting tighter is better. Concentrate on a subject and forget the dressing and you get better images. There is a whole school of photgraphers that restrict themselves in the focal length to get discipline and they get better images - I have found it helps me too! Which makes this an ideal walkaround lens for many photographers! It takes a real knack for those wide landscape shots, and if you like those, then go ahead and get a wide prime. I have found every zoom to be iffy on the wide end for focus - most cameras cannot focus a wide zoom properly to critical levels, so wide end on a zoom is no theme for discussion for me anyway! This Tammy does pretty close to prime lens performance from about 32mm (=50mm normal full frame equivalent) on and stays that way (excellent) all the way out to 75mm. Considering its weight and size being FAR less than an f/2.8 monster sized telezoom in the 70-200 range, and the fact that I get steady handheld shots due to its handling, it does better in many ways when cropped than said monster f/2.8 at four times the price and weight! Not to mention the reduced shoulder cramps not having to lug the weight around :) I would like to include my pbase samples in my lapratho gallery, but B&H is asking not to include html. I have proof from some Norwescon SciFi/Fantasy conventions though, that this lens is very good in flare resistance (NO flares!) with counter light portrait shots from a dark hallway into a sunlit window without flash - adjusted my RAW's levels, and was happy happy happy! As far as quality control is concerned, never mind, I have had junk gear from the most expensive manufacturers and real gems from the most questionable ones, so the mix is big with all of them. This Tamron is worth an order and they better NOT quit making it ever! I have no clue how to improve on a zoom lens, short of mounting a revolver mount with primes - and that would be insanely bulky and heavy and ... never mind ...
