SO) 28-75MM F2.8 XR DI F/CANON
From the Manufacturer
This ground-breaking high-speed mid-range zoom is prized by pros and serious shooters for its fast F/2.8 constant aperture, evenness of illumination, and its outstanding imaging performance, and by all photographers for its compact size and reasonable weight that make it feel like an ordinary standard zoom. These admirable characteristics have been achieved by the use of special XR and LD glass, the efficient use of aspherical elements, and non-rotating internal-focus (IF) design. This remarkable zoom lens also focuses down to 0.33m (13”) (1:3.9 magnification) at all focal lengths for satisfying close-up performance and is compatible with APS-C and full-frame-format SLRs. Not surprisingly it is widely acclaimed as a classic.
The most compact and lightest in the history of fast zoom lenses. Thanks to the revolutionary downsizing "XR" technology employed by Tamron in the development of high-power zoom lenses such as the 28-200mm and 28-300mm, the dramatic compactness that makes this lens the world's smallest and lightest is achieved. Its compactness makes it look and feel like an ordinary standard zoom lens, yet the versatility that a fast constant maximum aperture offers will definitely reshape your photographic horizons.
SP AF28-75mm F/2.8 XR Di Features
Digitally Integrated (DI) Lenses for the Best Imaging Performance
Di (Digitally Integrated Design) is a Tamron designation that applies to lenses that have been optimized for digital capture using advanced multi-coating techniques and optical designs that assure excellent image quality across the entire picture field. Because of these characteristics, Di lenses provide outstanding performance on cameras with full-frame and APS-C format sensors as well as on 35mm film.
Low Dispersion (LD) Glass for Greater Lens Sharpness
Super Performance (SP) for Discriminating Shooters
Tamron SP (Super Performance) series is a line of ultra-high-performance lenses designed and manufactured to the exacting specifications demanded by professionals and others who require the highest possible image quality. In creating SP lenses Tamron’s optical designers put their foremost priority on achieving superior performance parameters—they are all designed to a higher standard with little regard for cost constraints. As a result, Tamron lenses bearing the SP designation feature impressive and innovative designs that have established an enviable reputation for excellence among those knowledgeable photographers that demand the very best.
Extra Refractive Index Glass (XR)
Internal Focusing (IF) System
Internal focusing provides numerous practical benefits to photographers including a non-rotating front filter ring that facilitates the positioning of polarizing and graduated filters, and more predictable handling because the lens length does not change during focusing. Even more important, Tamron’s Internal Focusing (IF) system provides a much closer minimum focusing distance (MFD) throughout its entire focusing range. In addition, IF improves optical performance by minimizing illumination loss at the corners of the image field, and helps to suppress other aberrations that become more troublesome at different focusing positions.
Aspherical Lens Elements (ASL)
Zoom Lock (ZL)
Another original Tamron mechanical engineering concept is the Zoom Lock (ZL), a simple convenience feature that prevents undesired extension of the lens barrel when carrying the camera/lens unit on a neck strap.
Top Customer Reviews
I bought this lens primarily for low-light live music venues - my other lenses are all Canon brand prime lenses, with much wider max apertures, but I really wanted a lens with more flexibility in zoom range so I didn't have to carry two camera bodies around at venues to have two different focal lengths. I bought this lens with extremely high hopes and was so excited to test it out, and it simply didn't perform for what I needed.
1. Focus extremely soft at 2.8 - I have no idea if I simply received a soft copy of this lens or I was expecting too much compared to my prime lenses, but shot after shot the focus was just not sharp enough, even in bright daylight.
2. Autofocus "hunting" - Autofocus is extremely slow and clunky, especially in low-lighting. Seems to "hunt" for the AF point even when I have a single point selected.
3. Zoom. Ring. Is. TERRIBLE - the zoom ring is so hard to turn compared to other zoom lenses I have played around with, and is simply not smooth. The amount of force it takes to turn this thing is ridiculous. You can forget about taking video with this lens because if you want to zoom in or out, you will be struggling so much you won't be able to keep the camera still. The focus ring doesn't seem to have this problem. Again, I'm not sure if it's just my copy of the lens or if all of them have this problem.
I hate to be a "hater" and really had high hopes for this lens. I'm sure it would perform fine as a general walk around lens in generous amounts of light, but I prefer primes over zooms for that any day. It definitely beats the pants off of any 18-55 kit lens. I'm sad to return it because I wanted it to work out so badly. I guess you really do get what you pay for, I'm going to save up for the Canon 24-70 L

Let's get down to brass tacks, the pros and cons of this lens. I will tell you why I like this lens and how I use it.
I am a working photographer. I earn a living shooting weddings and events in Hampton Roads, Virginia. This lens helps me earn money because it produces great results in a wide range of applications. To be truthful, I push the limits of both my camera and the lighting situations I find myself in and would consider my knowledge at an expert level.
First there must be a basis for comparison. Lenses are not created equal, and the price of a lens is volatile, that is to say that once a professional level of optics are attained, very small advances in performance can come at a very high cost.
Therefore, I consider the Category, Sensor Size the lens is designed to work with, Distortion, Chromatic Aberration, Aperture, and Price, in that order.
CATEGORY: Constant f2.8 28-75 Full Frame Lens.
This Lens is competing with other Lenses with constant aperture at f2.8 with a focal length between 16-75. Tamron
Does offer a weather sealed version of this lens for around $1100. It has a pezio drive and is directly competing with the Nikon 17-55mm f/2.8G ED-IF AF-S DX Lens. You can find these two lenses here:
Nikon: http://www.amazon.com/Nikon-17-55mm-2-8G-ED-IF-Nikkor/dp/B000144I2Q $1399
Tamron: http://www.amazon.com/Nikon-17-55mm-2-8G-ED-IF-Nikkor/dp/B000144I2Q $1099
No, the lens does not have a sensor in it, but it is made for a Full Frame camera. You can use this lens on an APSC sensor size, which is good. Some even believe that you will have better results using a FF lens on an APSC sensor because of the crop factor pulling the sharpest part of the lens, the center area, into focus and discarding the edges of the lens.
Distortion, This is a legacy designed lens. This is important because the lens was designed when cameras did not have built in line correction and micro correction. Moreover, this lens was designed when the average consumer did not have access to programs like DxO Optics Pro 9 and Light Room (both of these programs have built in profiles to correct lens distortion on specific camera bodies).
This is important to you because it was designed when the lens had to be good optically because corrections in post production were very difficult. This lens Hit the market in the at least 2003.
This lens has some soft areas wide open at 28mm. They are mainly in the edges of the lens. Center is tack sharp. This is not a bad thing though, remember that an aperture of 2.8 should give a very shallow depth of field, and an extremely narrow focus. Therefore one would expect the edges to be soft. I absolutely love this. DXO optics has tested this lens and approves of it. But don't let someone else's numbers confuse you. All their numbers mean is that it is a great lens for the price. I'm sure that someone will begin comparing this statement to some $4k plus lens, but remember, this lens is not competing in the $4k arena. It does, however, hold up very well.
In my use I have seen very little to no distortion. I take portraits of individuals and groups, so I would not expect to see a lot of distortion. If I were taking photo of buildings, any distortion the lens has would become more apparent.
So far I have seen nothing that I would say detracts form the image. The Lens is prone to flaring when pointed toward direct bright light, like a sunset, but what better of an image to get than a silhouette of a bride and groom with a natural lens flair? For me its great, maybe not so much for you.
This is an f2.8, constant throughout the zoom range, right? Yes. but do you know what that means? Are all 2.8's equal? The answer is both yes and no. To make this simple, aperture is nothing more than a mathematical ratio. it actually looks like this f 1:2.8, We just drop the "1:" and display it as f2.8.
So now that you know it's a ratio, what is it competing? It is comparing goal length to the diameter of the aperture, or how big of a whole the aperture has at a known focal length. To find out how big your aperture is in MM just divide the focal length by the current aperture. So a focal length of 100mm at an aperture of 2 would be 100mm/2=50mm. This means that your aperture would be physically open by 50mm at a focal length of 100mm.
This is important because, as ratios are always comparing aperture diameter to focal length, they should be constant across different lenses. So you could say that a 50mm prime at an f2 has an aperture diameter of 25mm. The example above showed that a lens with a focal length of 100mm at an f2 would be 50mm in diameter. This is correct, but would be costly to build and quite heavy. Instead many lenses have an articulated aperture, which is to say that their maximum aperture changes throughout the zoom range. you will usually see something like an 18-55 f3.5-5.6. That means that on the wide end of the lens the max aperture is 3.5, so 18/3.5=5.14mm and 55/5.6=9.82mm.
This lens example from above is almost always going to be bad in low light, and would probably be a kit lens. The Tamron Lens that this article is about is a 24-75 f2.8 which means that the max aperture on the wide end is 24/2,8=8.57mm and on the zoom end the aperture diameter is 75/2.8=26.78mm. Let's compare them:
Common 18-55 f3.5-5.8 Max Aperture diameter wide angle: 5.14mm max aperture zoomed in: 9.82mm
Tamron 24-75 f2.8 Max Aperture diameter wide angle: 8.57mm max aperture zoomed in: 26.78mm
Bigger diameter aperture is better because it gives you more usable light in low light situations, it also gives you more control on depth of field.
PRICE: It's $500. This is a steal for this lens. It works in many situations and gives you the most control over your creativity- considering the alternatives, it is about ½ or less the price. I have truly enjoyed this lens and you will too. My suggestion is to buy the body of the camera you want- do not buy a bundled lens- and get this lens as your walk around lens.

This lens gets some of the sharpest pictures I've taken, and they really have a beautiful shine to them. I have a 7d Mark II body and consider myself a hobbyist, not a professional.
