I have the new sigma 150-500 with a nikon D600 and D750 and wondered if I could use my nikon 1.7 converter or if a sigma one is available. I took this photo yesterday but was about half a mile away and had to do some serious cropping

B&H has Sigma dedicated converters which are supposed to be very good.

I think Nikon is the only one with a 1.7 TC. It would take it to F10 and the AF would likely not work. It should manual focus OK. Look at the back of the lens and if the rear element is recessed it should fit w/o interference.

Try it and let us know.

Yes, you can manually focus - I would use a Tamron SP 1.4X - guaranteed to fit and work.

Personally, I would wait for a very clear day ( atmosphere), shoot with what you have at 550mm and f9 in RAW and use a very good interpolation software to crop and enlarge the image.

It is not a good ideal to use any TC for this kind of slow big zoom lens. Your final aperture will be come f10.7 with the 1.7x TC, and f8.8 with 1.4xTC. You better off be with out any TC.

I just bought a D7100 as a backup, but also because the images are already cropped to start with. I have the 150-500 as well and am looking forward to shooting the bald eagles when they start to nest here soon. My Sigma is a
225-750mm with this body. A refurbished D7100 is not much more than a good Nikon 2.0 teleconverter.

what software would you recommend for this

do a UHH search - this has been a topic before - I use the in camera Sony Clear Image zoom - but there are several other separate software solutions including Adobe's Bicubic which is built in to their software - you just have to use "bicubic smoother for enlargement" in multiple steps of 10% or less works best.

Half mile away? that as close as you could get?
