Originally posted by DogLover Look, the 70 is a great lens, I wouldn't fault anyone for choosing it over the 77, unless you already know that you like the FA Ltd. style of rendering. That is the most important difference between the two, and for those of us who have been bitten by the FA Ltd. bug, that difference is well worth every extra penny that it costs.
My subjective review of the FA 77 style of rendering:
1) Really sharp wide open.
2) Nice colours but lower constrast than DA. Easier to make the DA look like the FA in post than the other way around in this respect.
3) The extra stop is nice, but at 77mm, it's thin enough that I mostly shoot at 2.2, which isn't too far off from the 70.
4) Flare rejection is not good on a digital camera. Maybe it's just due to the hood, maybe the rear element is not ideal for a digital camera.
5) Bokeh is very smooth, but be prepared for psychedelic bokeh full of colourful fringing. I know that this is common with fast lenses, but it's not exactly desirable, and it does not vanish until about f4. Really hard to deal with in post without desaturating whole colour channels.
In other words, it gets some 10's and some 7's. At the asking price I would not fall over myself to recommend it to someone.
And from my experience with ANY of the limiteds, I must say, that this pixie dust nonsense should stop because it is simply not true. The FA / DA limiteds render very nicely, but the magic is in the photographer (who could also take a magical picture with an FA 50).
On the other hand I think the macro would be nice for the OP to have because it would serve a dual purpose, and for portraits, 2.8 is plenty at 100mm.
