This review is from: Tamron AF 28-75mm f/2.8 SP XR Di LD Aspherical (IF) with Built-In AF Motor for Nikon Digital SLR CamerasIt's been about 2 months that I've had this lens and it almost never leaves my camera. I'm came to buying this lens after being lured in by the ever-so-attractive constant f/2.8 aperture. It was a contest between this lens and the Nikon 16-85 f/3.5-5.6 VR and now, I know I've made the right choice.First and foremost, the constant f/2.8 is what makes this lens worth every penny. I don't know how I ever got along with my old 18-55 kit lens. Here's a little breakdown of the good and bad of this lens:THE GOOD:- Constant f/2.8 aperture (*angelic singing*)- Extremely sharp even wide open at f/2.8 (although I'd recommend f/4 for maximum sharpness)- Zoomed in at 75mm and wide open at f/2.8, this lens makes beautiful portraits with nice bokeh.- On a purely subjective scale, bokeh is pretty awesome, 8 out of 10.- Focusing is relatively fast and very accurate (about as fast as the 18-55mm kit lens, which is almost always good enough)- Zoom action is well damped although I would've appreciated a very slightly shorter throw between 28 and 75mm.- Autofocus/Manual focus switch conveniently located on the side of the lens.- Internal autofocus motor! (Works on my D40x, will work on D40 and D60 also)- Close focus ability enables shots with a closer perspective.- Metal mount is always a good thing to see.- Looks pretty awesome on the camera :)THE BAD- For travel and other things, 28mm will not satisfy some, buy a wide angle (and telephoto if you need it) to go with this lens.- External focus ring moves during autofocusing (keep your hands away!)- Focusing is noisy (much noisier than my AF-S Nikkors and HSM Sigmas)- In manual focus-mode, the focus ring is a tad loose- Lens hood doesn't seem to work too well, doens't look that great either, in my opinion.- Rear lens cap sucks, throw it away and buy a Nikon one.OVERALLI'd rate this thing 4.5 stars if I could, but I gave it 4 so as not to give the impression of a fault-less lens.This lens has a great deal of good points and very few bad ones. Most of the bad I attribute to the construction of the lens: somewhat solid, but not. It's a little loose inside since it zooms and is made mostly of plastic. Optically though, the lens is amazing, especially for the price. For me, it's created amazing portrait work, some cool close-up (see the "PS" section at the end) shots, and many others. Until you build up the money and arm strength to buy and haul around the Nikon 24-70 f/2.8 go with this lens. You cannot pass this up for the price, it's capable of so many things, and all for about 400 bucks.PSTamron may call this "Macro" but it's not really macro, it's more of a close focus (I have the Nikkor 60mm Micro, and this is not it). However, the close-focus can be really useful and can add some creative shots to your collection. However, do not confuse this lens with a real macro lens, it can't focus as close and can't reproduce 1:1....
This review is from: Tamron AF 28-75mm f/2.8 SP XR Di LD Aspherical (IF) with Built-In AF Motor for Nikon Digital SLR CamerasI purchased this lens to use for the majority of my shooting on my D300. I have one of the latest copies with the built-in motor. I'm amazed at its focusing capabilities with the D300 - fast and quiet. Images are sharp as a tack and the blurred background is perfect at 2.8. You can easily see the three LD glass elements at work! I enjoy this range (28-75) for everyday shooting and portraits. Also, the macro capabilities of this lens makes it a fun one to keep on the camera. I sold a more expensive new Tokina lens and this thing blows it away in sharpness and color contrast. I was a little curious of Tamron's build quality, but this SP lens is very good quality, especially for the money. Low light and indoor photos on the D300 have been great with this lens!I can't say enough about this lens. You get a lot for the small price of this lens...buy it, if this is the range your looking for. It fits perfect in the gap of my other lenses: Sigma 10-20 & Nikon 70-300VR. GREAT GLASS!!...
This review is from: Tamron AF 28-75mm f/2.8 SP XR Di LD Aspherical (IF) with Built-In AF Motor for Nikon Digital SLR CamerasTamron AF 28-75mm f/2.8 SP XR ZL Di LD Aspherical (IF) with Built-In AF Motor for Nikon Digital SLR CamerasI bought this lens for my Nikon D700. This is a full frame lens. The max aperture 2.8 is available on all focal lengths. Tested this at various focal length/aperture/shutter combos under different light conditions.Here are my observations:Pros:1. Awesome value (price/performance). Nikon and Sigma equivalent costs more (nikon way too much). 2. Decent walk-around lens covering key focal lengths of mid range zoom3. 2.8 aperture available at all focal lengths4. Relatively fast and quick to focus5. Great DOF (min aperture 32) 6. Pleasing blokeh effect (shallow DOF)7. Usable sharp picture at 2.8. Stop down to 4.0 and you can get realy sharp pictures8. Surprisingly decent close-up performance at various focal lengths (including 28mm). I was able to shoot a 2" x 2" object at 28mm at a distance of about 6-8". This was taken under room light conditions with flash from nikon d700. The pictures were sharp, and usable. (Will post pics later)9. Less weight compared to other lenses in this class10. Price, Price, Price !!Cons1. Sometimes hunts for focus. This could be my camera setting (I have set focus priority for shutter release. I have to change this setting and try it out)2. Nikon and Sigma will be better built lense...
