I picked up this prime lens today. She’s a little old school (first released in 1989). With no focus drive it is a little slow in auto-focusing as you would expect (you have to keep your fingers away from the front of the lens as the focus ring physically turns). Manual focus is fine obviously.
Note this lens will not auto focus on an entry level camera (Nikon D40 for example) but will work on a D90 or higher etc. I am surprised Nikon hasn’t released an F1.4 full frame version of this lens considering you can now buy an F1.8 DX version.

Size difference beside a 28-70mm lens – a lot lighter and easier to handle.

Photo examples: these are only a few quick hand held examples.
F2 – Extremely soft wide open.

F2.8 – The lens is far far sharper.

F4 – This is generally the widest I would personally be shooting so I am more interested to see how it goes at this range.

F5 – Upon intial testing the lens is probably at it’s sweetest spot from F3.2-6.3.
