Telephoto zoom lenses with tele-macro function and optimised for digital SLR cameras
The performance telephoto zoom lens is capable of shooting with a maximum magnification of 1:2 at the focal length of 300 mm. It's the ideal lens for portraits, sports photography, nature photography, and other types of photography that frequently use the telephoto range.
SLD (Special Low Dispersion) glass
This lens has two SLD glass elements in the front lens group and one in the rear lens group, the lens has excellent correction of chromatic aberration through the entire zoom range. This new DG lens is capable of macro photography with a 1:2 maximum magnification at the focal length of 300 mm. The new multi layer lens coating reduces flare and ghost, which is a common problem with digital cameras and also creates an optimum colour balance
Macro shooting with maximum magnification 1:2
High optical performance is demonstrated throughout the entire zoom range. It also has a switch that converts the lens to macro photography at focal lengths between 200mm and 300mm with a minimum focusing distance of 95cm (37.4 inches). In normal mode the minimum focusing distance is 150cm (59.1 inches) at all zoom settings. Maximum magnification between 200mm and 300mm is 1:2.9 to 1:2.
I do mostly nature photography. This lens along side similar lenses performs well and the price is well below what I have paid for my Nikkor lenses. It is light, quick and appears to be sharp on the computer screen. I have not made any large prints yet.
I mainly use this to shoot local birds and small critters with the use of the macro/telephoto function. This lens is very sharp. It's actually sharper than my kit 18-55mm lens that came on my D3100. The lens is a little soft at 4-5.6, but gets really sharp at f8. The lens has some weight to it and it feels pretty solid. The macro function works between 200-300mm and still produces sharp results! I am extremely happy with this lens. So sharpness, contrast, and its macro function are all positive. It's a very good lens. Now, the only thing that I am not too fond of is the focusing time. If you're using auto focus, the motor takes awhile to focus, but it gets the job done. The motor itself is a little loud. Other than that, it's a really good lens for its price and I highly recommend it to others looking for a great telephoto/macro lens at a bargain price.
This is the second of this particular lens I have purchased, and for the price it is certainly worth it. After I dropped my lens, I had considered several others that were considerably more expensive and faster, but after careful consideration I chose to got with this lens, considering all the great photos I got with my previous lens. The optics are good throughout the range, and the close focusing capabilities are one of the major reasons I love this lens. I do confess, the major drawback is the noise, and it is not particularly fast, but for shooting from a distance it should not present a problem.
used it on to take pictures of a barn a 1/4 of a mile away. did a great job. barn edges were straight, very clear, weight don't even notice. Keeps up great with moving trains.
Professional photographer taking flora and fauna. Sometimes use with a 1-4 teleconverter and lens works well in AF with it
This is fantastic value for an entry level zoom lens. I use it on my Nikon D3100. Yes, the auto focus is a little slow, and it is a bit noisy however I can not be happier with this purchase. I wanted a telephoto lense, since I only have the 18-55mm kit lens the D3100 came with. After reading review after review, I pulled the trigger on this one, and happy that I did.
This Sigma lens is well built and feel solid. I am impressed by its quality considering the price I paid for it. The auto-focus is noisy and slow, but it gets the job done. Macro is down to 1:2 @300mm, very useful for taking macro pix of flowers, gritters and pets. You have a 3+ feet working distance. With the 9-blade diaphragm aperture construction, it makes a fine portrait lens with pleasing Bokeh. However, I would not recommend it for Sports or Hyperactive kids.

Using this lens all the time with the 18-55mm one. Takes great photos and the price is affordable. Although, it doesn't come with VR.
It works well for the little amount I use it for.
