"Sigma 150-500" Thu 21-Mar-13 04:16 AM by paulfree17
I have a lightly used Sigma 150-500. I am selling it because I recently ordered a 70-200 F2.8 VC and plan on getting a 1.4 or 2X converter at some point.
The lens is in excellent condition as I have only used it on 2 occasions when taking nature photography workshops. It is a heavy lens and my technique does not provide for hand holding so I always used it on a tripod.
Adorama is selling it new for $1050. This lens has probably been used for under 200 shots. The lens is pristine but the carrying case is a little dirty. Includes original box. I will sell it for $900 plus shipping ($20.00) anywhere in US or Canada.
I found the how to somewhere on this forum, but couldn't find it again to post a link here for you. basically the focus pin on the Sigma 1.4 Tc is the first pin, you just cover it with a piece of scotch tape.
I not sure about the Nikon tc working on other lens'
You might want to ask that question in the lens forum.
I am a former owner of the Sigma 150-500, having just sold mine. Many folks do not seem to understand that the reason why sometimes third party lens like the Sigma will not focus on some Nikon bodies is due in part to certain factors like: 1. Sigma (and other third party lens) are reverse-engineered to work on Nikon, Canon or other bodies. Depending upon the age of the lens and its currently installed firmware and model of the camera body, it may or may not AF with certain bodies. (e.g., a Tamron 200-500 that has a screw drive AF connection will not AF with Nikon bodies that do not have a screw drive connection). Yes, the Sigma 150-500 worked on my D800E, my D300 and my D700 (which I no longer own). Some have reported issues with the D7000 (some work, some don't - and I don't know why). If the lens is a few years old, it can be "re-chipped" to work with certain Nikon bodies. 2. Depending upon the Nikon body model, some Nikon bodies will not auto focus the lens if the lens exceeds a certain maximum aperture, often past f/5.6. The Sigma lens is a variable aperture lens - from f/4.5 to f/6.3. Some Nikon bodies will not auto focus when the maximum aperture (does not matter if you've stopped it down or not) is f/5.6 or less. So, if one zooms out to 500mm, for example, the max aperture is f/6.3. So, the lens may not auto focus. However, zoomed into to a focal length where the lens is f/5.6 or greater it should AF.
Lots of folks seem to want to use teleconverters with the Sigma long zooms. That's a bad idea since the maximum aperture will then exceed the AF cut off point for almost all bodies. Remember, a 1.4 TC will reduce the max aperture to f/9. Also, the lens becomes so slow and the image so soft as to make the image not sharp at all.
I don't know if a Sigma lens can mounted to a Nikon TC. Others may know, I've never tried it.
