Beware rant!
Found a cheap cheap Sigma 105mm macro boxed complete and in perfect condition for 120 euros.....screw-drive version.....I had the same in the Pentax mount...
Very well centered and really sharp wide open.....a little LOCAs but other than that an excellent optical performance!
AF........well here we go again with Sigma.......on the D750 (Nikon lenses have around normally 0 +- 1-5 AFFT) this Sigma requires more than +20 to reduce front focus to just a little!.....
.............on the D500 which also hardly needs AFFT gererally; it needs only +5 to nail the spot!
...my AF50mm F1.8D has an adjustment of +3 on the D750, on my friends D600 it needs more than -20 and still isn't enough.....His camera needs to be calibrated by Nikon, so we called Nikon France, they want 90 euros to calibrate the AF post included both ways, less than the fixed charge of 130 euros from Canon, but nontheless, for Nikon it's good earner...no wonder they stick with DSLRs.
If you have just one body then once calibrated your fine, but throw three bodies into the mix and all hell breaks loose!
So ML fans will pleased to hear "me say" that if starting again especially in portraiture,
I would never ever pick another DSLR
..for anything other than birding!
.... ..........between my two bodies and my friends recently found, it has been a constant round of AF problems....and the whole thing isn't over yet!
Two Sigma macros (105mm +150mm EX macros) and both can't focus accurately for portraiture and only the 105mm works in LV, so I suppose I'll put a trilby hat on and shoot like Jason Lanier in LV!...
Thank god for my AF85mm F1.8D..... , like most of the Nikors at least it focuses fine.
I mean really !
