Testing a Huge SIGMA 170-500mm f5 Zoom --

[pentaxpete]

a Lady Member of Brentwood Photographic Club bought a huge Sigma Zoom 170-500mm f5 NIKON fit and after finding she needed to go to The Gym to get get Muscles Up wanted to sell it to another Club Member but let me test it -- well it is really for 'Auto-Focus' but has a small 'Manual Focus' ring -- so I could use it on a FILM Nikon -- my Wife's Nikon FE that she never uses now so I have 'Taken it over'
It really must be used with a support of some kind -- I used a MONOPOD but still found it difficult to manage. When I focused correctly the results were sharp even at full aperture f5 . Then my friend from Club tried it on his 2 Digital Nikons and found it was ;Not Compatible for Auto -Focus' and as he suffers from 'Shaking Hands' could not use it after all.
Here are MY results on FUJI SUPERIA 200 ( should have been 400 ASA as many showed subject movement of the birds)

The movement on that duck’s wings really adds to the photo Peter.

IIRC the 170-500 is screw driven so won't AF on all Nikon DSLRs. It should AF on any film AF Nikons though, I think they all had screw drivers.

Well done MFing it!

Mr NOD -- That must be the explanation ! I will pass it on to my Friends -- Thanks !

I believe that all the Nikon D3*** and D5*** range APS-C DSLRs will not allow auto-focus with a lens like this as they lack a built-in auto-focus motor. The D7*** range have AF motors in the body though and will provide full functionality.

Not sure if any of the Nikon full-frame or mirrorless ranges lack AF motors in the camera body though?

Sigma used to do a re.chip process but not sure if that applies

Pete, do you still have access to this, looking for a low budget moon buster on my Sony A7 with a dumb adaptor and this length would be great @ 500mm
