18-105mm variable aperture vs. 28-75 fixed 2.8 aperture
Apr 15, 2013

this is a follow up to my previous question. I previously had the nikon 18-105mm 3.5-5.6 lens and sold it with my camera. I need a replacement lens and would love something with a lower fixed aperture but the only thing in my price range is the tamron 28-75 2.8.

How do these two lenses compare? I'm not opposed to buying a new 18-105 as I really loved the zoom range and got some outstanding pictures with it. But the lower fixed aperture on the 28-75 is very appealing to me as I love bright shots. Does one lens out perform the other? I'd hate to buy the tamron and find that I miss the lower and upper range of the zoom or don't really benefit from the 2.8 fixed aperture.

If you didn't see my previous post I have a d7000 a 50mm 1.8 and 35mm 1.8 prime and a 70-300mm 3.5-5.6 zoom.

Setting the known focus shift issues of the Tamron 28-75 f2.8 aside, the range is a very poor one for APS-C because you totally lose wide angle. Instead I suggest you pick one of the following f2.8 lenses.

  • Tokina 16-50 f2.8 is no longer in production, but some good used ones are available on ebay and Amazon. This is the lens I use most. It is soft at the edges at f2.8, but sharpens up nicely to the corners by f5.6. Micro-contrast is exceptional and bokeh is creamy. Build quality is excellent, but no VR and no lens motor though. (I picked up mine used for $300 from a local seller.)
  • Tamron AF 17-50mm F/2.8 XR Di-II LD SP, is relatively inexpensive, especially used. If you get a good copy it is very sharp stopped down and also quite sharp at f2.8 as well. It has mediocre micro-contrast, and bokeh is not creamy and disappointing and there is a little too much CA wide open. This lens has a motor, but is a bit slow and noisy. This one has no VR. The VR model is reportedly soft at f2.8.
  • Sigma 17-50mm f/2.8 EX DC OS HSM FLD, has VR, lens motor, good bokeh and very good micro-contrast. It is also sharp, if you get a good copy. The main downside is that the focus ring moves when focusing and there is no direct manual focus over-ride. 

Some examples with the Tokina 16-50 f2.8.

Decisions, decisions!
