Originally posted by Ash Careful there Boris. The 43 cannot be compared at f/1.6, so is that why you say it is 'infinitely' sharper? The same could be said at f/1.4 and f/1.8 but this is a moot point. The 43 is not soft at f/1.9, and where it can be compared with the FA 50 at f/2, it is of comparable *sharpness* however not in microcontrast and colour rendition, after which the FA 43 trumps the FA 50 in every measurable parameter.
You understood me exactly right,
Ash. FA43 cannot open to f/1.6. FA 50/1.4 can. With all due respect to micro-contrast and color rendition, photographs I
printed from either lens look wonderful in print. In fact, I don't notice any differences between the way FA43 and FA50/1.4 render color, but I know (and openly admit) that I am blind to subtle color variations, so indeed, my opinion may not be representative in this regard.
I do know that FA 43 is approximately twice as expensive as FA 50/1.4 whereas it is certainly better but not twice as much, may be by 10% if things such as image quality can be compared by percentage point, which is a silly notion to start with.
Although I do have all three FA limited lenses, use them and really like them, I don't subscribe to the "limited holiness" notion.
In a nutshell, FA 50/1.4 offers 90% of what FA43 can do for half the price. Everyone would then have to make their own choice and it is not at all a trivial one. To a beginning photographer I would suggest FA 50/1.4. To a seasoned veteran, so to say, my suggestion would be irrelevant 'cause they would know themselves what do they need.
