User Ratings and Reviews

5 Stars Canon Lens
This lens was purchased for use with a Rebel and has been excellent. It was ready to use the minute it was taken out of the box. Quality in both low light and normal light has been excellent. It is lightweight thus carrying an extra lens is not an issue. These lens are much smaller in size than the Nikon lens I use for my Nikon cameras.

1 Star I Got the Lemon
Very suprised by this product. High expectations were dashed after I installed the lens in my camera an attempted to operate it. The rotational zoom mechanism is ‘sticky’ which makes it jump as you are trying to zoom and focus. I don’t know how it got thru the QA check. Anyways I have reported it to Canon and am waiting for a response. Very unhappy with it right now.

4 Stars Great lens
A great product for the price. The lens is “fast” enough for almost every application, and the wide zoom range lends itself to most situations. It is compatible with the Canon system and works in the auto-focus or manual-focus mode. I am pleased with this product.

2 Stars Wish I had bought the 70-300mm
The UPS man just dropped off my lens and I ripped it open eager to play. I am completely happy with the service from Cameta Camera, they were fast and I received exactly what I supposed to. I can only hope they will be as accommodating if I return it. I am very disappointed with my lens however. I wish I had paid heed to some of the more negative comments.

I am using this on my Canon Rebel Xti. I am an artist and amateur photographer but work with my photos for montages and artwork so I need clear pictures. If I want it soft, I’ll do that in Photoshop myself. My pictures are way to soft for my liking. To be fair, it is a cloudy day and I’m shooting through my window. I have no reflection, but I cannot zoom all the way to 300 and get a crisp photo. I cannot even get a crisp photo in the 75 range in this light. I’ve played around with the iso and the speed and still no crispness. Maybe I misunderstood that this lens was for fair conditions (meaning not sunny outside). Maybe it is for outdoor sunny use only, but I have not read that on the Canon site. I do plan to give it another try in sunny conditions before I send it back. (I have 14 days to return and will lose my shipping costs both to and from.) Inside with normal can lighting (like in a kitchen) is just as bad.Canon EF 75-300mm f/4-5.6 III Telephoto Zoom Lens for Canon SLR Cameras

If it performs well in the sunny conditions, I will have to decide if it’s worth the $ for just perfect conditions. I am very close to forking over the extra $$ for the 70-300 mm. But will post again, probably an edit or addition to this review.

If someone (like a pro) can tell me if I have unrealistic expectations of this lens, please tell me.

5 Stars Christmas Gift
This item is going to be a Christmas gift for our daughter. She loves this lens and wanted one of her own.

5 Stars Tamron Lense
I am a novice photographer. Alot I do not know. I ordered this Tamron lense thru Amazon. When it arrived (timely), it caused my camera (Canon Rebel Xti)to shut down. Would not work. I contacted Tamron and explained the “error msg” I was getting from the camera and after brief conversation w/tech person at Tamron it was determined that the lens was flawed and for me to contact Amazon and explain this and get a replacement lens. Uh-Oh, right? Let me tell you that a call to Amazon was all it took. A new lens was shipped that day express mail (free of charge) with an authorization label to send the faulty lens back in the same box with charges reversed to them. The new Tamron lens arrived and is working beautifully on my camera. Bottom line? This is a fine lens and Amazon (in my opinion) is one great and reliable company that I will use without hesitation.

1 Star Very fuzzy
Disappointed with the lens. Not clear at all and very slow to focus. I returned it immediately.

1 Star Slow focus
I am a professional wedding photographer and I tried this lens on my canon 7D at my daughter’s Halloween party at school. I’m glad I didn’t bring it to a wedding off the bat. The room (as most school rooms are) is well lit from windows and the florescents were on – the lens couldn’t pick up on the dark costumes to grab fast enough. It hunted a lot and I lost some shots. At the widest, there was A LOT of blur around the edges. Not a crisp shot. I returned it today (after receiving it the day before yesterday). I do have another Tamron zoom that is slow to focus, but this one was much slower in lower light – would not have worked at a wedding ceremony (especially a church) nor a reception.

4 Stars Upgraded from stock lense
I bought this lens to upgrade from the lense that came with my Rebel XTI. I used the “old” lens (18-50mm) on a two week trip to Scandinavia last year and did not bring a longer one due to luggage limits. I bought this one for a three week trip around the Canadian Maritimes this fall and it provided much more flexibility in the shots I could take using just one lens. As for improved quality of the photos, I guess its hard to say since I sharpen all of my photos and when framing an image in the view finder, I allow for a little cropping during post-processing in Photoshop. I much prefer it to the original lens for the range of shots I can take while travelling without having to switch out lenses.

1 Star Bad Leans
I don’t recommend this Leans, the one I got it is not sharp and all the pic it takes are soft and not sharp

maybe the one I received is like this but I can write a review for the product I got

Tamron AF 28 75mm f 2 8 SP XR ZL Di LD Aspherical IF for Canon Digital SLR Cameras




Tamron applies the Di (Digitally Integrated) logo to lenses with optical systems designed to meet the performance characteristics of digital SLR cameras, and this 28-75mm Di autofocus zoom lens is no exception.

In fact, it looks just like an ordinary standard zoom lens, but offers a fast constant maximum aperture that will reshape your photographic horizons. Specific details include a constant maximum aperture of f/2.8, a minimum focusing distance of 13 inches, and a rotation-type zoom. As with all Tamron lenses, the 28-75mm lens carries a six-year warranty.

  • Lens construction: 16 elements in 14 groups
  • Angle of view: 75 to 32 degrees
  • Zooming type: Rotation
  • Diaphragm blade number: 7
  • Minimum aperture: f/32
  • Minimum focusing distance: 13 inches
  • Macro magnification ratio: 1:3.9 (at 75mm)
  • Filter diameter: 67mm
  • Accessories: Lens hood
  • Mount: Canon, Nikon, Pentax, Sony
  • Dimensions: 2.9 inches in diameter and 3.6 inches long
  • Weight: 18 ounces

5 Stars tamron via canon
IDEAL WALK AROUND FRIEND OF YOURS

MONEY SAVIER

MY BELIEVE JAPANIS TECHNOLOGY TYPICALLY PARALLEL WITH EACH OTHER , EVEN DIFERENT COPMANY’S SHERE THEIR SECRETS ..TO SUPPORT NATIONAL MARKETING IDEAS ..

28-75mm autofocus zoom lens with f/2.8 maximum aperture

EXELENTLY meet performance characteristics of digital SLR cameras

Minimum focusing distance of 13 inches; rotation-type zoom

Smaller and lighter than most fast zoom lenses; weighs 18 ounces

Measures 2.9 inches in diameter and 3.6 inches long; 6-year warranty

DO NOT THINK TOO LONG !!

If you are here you are not the only one who use it ( proudly ?!!!)

5 Stars High quality optics
I have both the Canon 24-70 and this lens. The quality and sharpness of the image taken with this lens is outstanding. I really can not tell them apart from the Canon (BOTH PIN SHARP). I use this on my back-up camera but it’s easier to carry around for a long period of time – much lighter. The build quality of the Canon is better and it is a much sturdier lens. The Canon has full time manual which I need when shooting weddings – I was concerned with damaging the Tamron which does not have full time manual. Overall this lens is an outstanding value – I would not hesitate to buy it.

4 Stars Great for indoor sports
I had problems taking indoor basketball shots with the f3.5 zoom, and this f2.8 zoom solved my problems at 1/2 the price of a canon.

4 Stars Good Value for a Fine Lens
Not having the change to spring for the Canon “L” equivalent, I did my research and decided this would more than suffice. Having used it for some recent photos, I can say it was a good decision. Build quality seems quite good and the zoom mechanism has just the right feel. Sharpness at normal aperatures is very good and even at f2.8 is not too soft on my Canon 20D. Should make a good ‘walkabout’ lens and even a credible portrait lens at 60mm+ (although it is hard to beat the portraits taken with my 50mm f1.4). There is a little autofocus searching under dimmer light conditions, but not bad and certainly not a problem for normal landscape photos that I like to take. Comes with a short hood, unlike many Canon lenses. My first Tamron. Nice job Tamron!

4 Stars Tamron AF 28-75mm f/2.8
I’m a novice photographer and for me this was not only a steal but a huge upgrade. Seems on par with the standard Canon line of lenses in terms of construction.

Canon EF 75 300mm f 4 5 6 III USM Telephoto Zoom Lens for Canon SLR Cameras




This compact and lightweight EF 75-300mm telephoto zoom lens is ideal for shooting sports, portraits, and wildlife. The lens is distinguished by a newly developed micro ultra-sonic monitor (USM) that makes autofocusing quicker and quieter, along with an improved zoom mechanism that includes a silver ring on the front for a luxurious touch. The micro USM makes this version of the lens particularly suitable for applications that require a fast autofocus, such as sporting events or wildlife shoots. Best of all, the USM version shares many of the same features that makes the non-USM lens so popular, such as a compact size, a close focusing range, and accessory compatibility. As with all Canon lenses, this unit carries a one-year warranty.

  • Focal length: 75-300mm
  • Maximum aperture: 1:4.5-5.6
  • Lens construction: 13 elements in 9 groups
  • Diagonal angle of view: 32 degrees (at 11 feet) to 8 degrees (at 15 feet)

5 Stars Cannon EF 75-300mm lens
The lens was everything I had hoped it would be. I take pictures of my kids’ soccer games. It allows me to get up close and personal and gives me great action shots.

3 Stars Was free with the deal I did, but…
I got it free with my new camera, but I wish I sold it and bought a 55-250mm with IS or a 18-200mm with IS. They are much more expensive, but I hate having to remove it to put on a 18-55mm IS lens for indoor or closer range things. I can’t complain too much since it was free. It’s just that to fit in my camera case well this must be attached and in most cases I need to remove it and grab my other lens to take a picture. Not a bad lens, but you may get annoyed when you want to switch back and forth like me. Don’t let this review deter you from buying it, I just had to put my two cents in.

4 Stars It was good enough for me.
I have EOS Revel T1i, and very very beginner. That being said: I have 10-22mm ultra-wide, and 18-55mm standard zoom, and they are both fine, but I just wanted a lens that goes above 55mm.

So here it is. I do not have any complain about the picture quality so far, I just wanted to see what 300mm is like, and its definitely a different world, and I am happy to know that. USM is pretty nice too, so you may want to spend a few more bucks on it to get it. My standard zoom lens has standard motor and its slow and noisy. Anyway, I got what I expected, and again, I am happy.

5 Stars A very good telephoto lens with great price!!!
This is a great telephoto lens with very quick and accurate focusing. I am using it with my Canon XTi 15.1Mpixels and I got great photos out of them! At high zoom you get less light going inside the lens but when you have to choose between 100 – 3200 ISO this is not a problem! Overall a good lens whit good capabilities.

3 Stars One word: unpredictable
Looking for lenses for my Canon Rebel XS, it was hard to find any within my price range, let alone under $200. I came across the Canon EF 75-300mm III USM telephoto zoom lens for a reasonable price, and pulled the triggered and bought one.

If I had to sum up my experience with this lens, I’d use one word: unpredictable. This is not a bad lens, because it takes many great pictures. Conversely, this is not a good lens, because it takes many bad pictures. I’ll elaborate below:

PRICE

This is a really good price for an additional lens. Yes, it may seem expensive, but when you compare to other lenses on the market, it’s pretty reasonable. If you’re on a very tight budget and are looking for a telephoto zoom lens, this is great

AUTO-FOCUS

This I felt was at times very slow, which was very frustrating. Assuming you’re buying a telephoto lens for capturing fast movement – say, a bird in the distance, or a sporting event – this can be very frustrating. A lot of my photos from a recent family trip to Aruba were ruined because either (a) I couldn’t capture the moment, (b) I captured the moment, but out of focus. I cannot emphasize how frustrating this is!

MANUAL FOCUS

As a natural extension of my previous point regarding auto-focus, I found myself using manual focus a lot. I have taken some amazing pictures on manual focus, but this can be inconvenient, say you’re shooting something that is moving, etc.

RELIABILITY

If you’re looking for a reliable lens that time and time again produces nothing but very sharp, in-focus pictures, this is not your best bet. If, on the other hand, you’re a beginner, just learning to play with your DSLR, and want a telephoto lens to practice with, go for this. If you can afford to upgrade to a better lens, however, I’d suggest you do that.

  • Lens construction: 16 elements in 12 groups

User Ratings and Reviews

5 Stars Nice lens
Great lens. Usual Canon quality. I look forward to taking lots of pictures with it.

4 Stars love it!
I absolutely loved the versatility and picture quality of this lens!! love it, love it, love it!! Also, I received it a lot quicker than I expected!!

3 Stars not impressed
This lens came rattling in a plain box, wrapped in bubble wrap. Focus and contrast was not as sharp as I expected – perhaps the poor packing/shipping had some effect on this or perhaps it is a bad copy. It makes me wonder if this lens wasn’t the same one that a previous customer returned, since I remember reading a review that mentioned the lack of box and manual.

5 Stars Great alternative to the L glass
If you can’t afford to buy L glass, this is the way to go. I debated for a long time between this one and 24-105L and finally decided to get the 28-135 instead. Mounted on my 40D, I get results that are very close to my prime lenses. Not as sharp, but close. I’ve yet to have problems with autofocus, even in dark room and the USM autofocus is great. The only downfall of this lens is the construction – the lens is a bit wobbly and the zoom creep is present if you point the lens down.

5 Stars This lens came with my Canon 40D, and I like it – a lot.
I’ve only recently gotten my Canon 40D and, as I said in the title, this lens came with it. So far, I am really happy with the detail it came capture.

I added an image of a Downy Woodpecker to the images area and the detail of the bird is very good. I’m still learning how to use my camera and lens, but so far, I am really happy. The picture was taken late in the afternoon, in the shade. I couldn’t see the bird all that well. I had the 40D on auto and the lens all the way out (max mag). I used Picasa to lighten the pic and was really happy with what I ended up with. It sure didn’t look that good in the tree.

I guess, when I get more proficient with the camera, I’ll be able to take better photos, but with Picasa, I’ll be okay.
