It's interesting that in 2010 I wrote a piece in my blog on smart lenses:http://www.esp-sportsphotos.com/Nikon-Talk/?p=133Perhaps someone from Sigma read my blog and thought it was a good idea....

I have owned a handful of Sigma, a few Tamron and  of course Nikon.  If your looking for a broad recommendation, it honestly does not exist. You really have to look at  very specific lenses and...

I would second the Nikon 28-105D, if you need the reach I think the Tamron 70-300 VC is better at the long end and was selling for $350 new with a rebate. If you don't need the reach the Nikon...

Regardless of how the item came to be refurbished, it has a pretty limited warranty, usually 90 days from Nikon, but some resellers add another 90 days so you get 6 months. Is the cost savings...

Doug, your assumption is that the commission from KEH is reasonable. But the fact is they typically only pay about 50% of what the used lens is worth retail. So if you have a 300mm f2.8 lens that...

In the USA Fred Miranda and Nikonian Forums are both good places to sell used equipment.

I use a 300 f2.8 plus TC's with the BH-55 and a decent tripod. Its fine for tracking things that move across with some changes in elevation. I have never tried to shoot birds in flight, a Wimberley...

This is actually an interesting question. Because DOF does change with camera to subject distance. The easiest way to see the result is with an online calculator. If you take a 300mm f2.8 and put a...

Hi Mike, Those are nice shots. Would you have any examples of good IQ at f5.6. Many people are interested in how this lens performs wide open with and without a TC.

Take a look at the Nikon 28-105 D lens later versions are very sharp and the lens has an aperture ring. If you need longer reach I would second the Nikon 80-200 D f2.8.

Interesting that the lens will be sold for about the same price as a 70-200 f2.8 and a TC. The question is will it have better IQ and sharpness at 400mm. Has the focus speed issues been resolved?...

Hi Rich, I bought it so that my wife could shoot out doors at the beach etc. In those conditions it's fine; as others reported similar in speed to the Nikon 70-300VR or say a Nikon 16-85G AFS. When...

I agree and that's what I have done if you can live without a zoom. The 300 f2.8 gives a lot of flexibility and optically works well with all three TCs if you stop down a little. It also handles...

I took a few quick shots with my wife's D7000, the new Tamron 70-300 VC and my trusty Nikon 70-200 f2.8 VR I with a 1.4TC. These are hand held shots with VR / VC turned on from about 6m away, aimed...

Just to be clear I am referencing the Tamron which most people rate higher than the equivalent Nikon 70-300 at the long end. My comments are also based on 70-200 f4 with a TC compared to the Tamron...

Another option is the Tamron which is currently selling for $350 with the rebate. I was debating the same choice, but didn't want to spend $1400 dollars (it's a lens for my wife). I am sure the new...

I am in the same boat as a previous post, I don't keep expensive lenses that I don't use. I have a hand full of AIS lenses that are not that expensive and I appreciate the quality and minimal...

The full Mg frame and a couple of fps are missing. Are those really enough to justify a seperate body and how much more would that be worth? The D7100 is going to sell for $1200 dollars. It has the...

My 2 cents is that you won't see a D400 until the new mirror less technology is ready for a DX size sensor with a good AF system.

I agree with Mike, add a wide variety of subject to lens distances and it makes it hard to compare. You really would have to do a test at the same time with the same subjects at the same distance...
