FA43 vs FA50

so i did some non chart tests today at F1.8/1.9 F2.0 between these two lenses by photographing a portrait in outdoor lighting of a girl.


honestly? i dont know... hahahahah

both cover a full frame

both are pretty small, the FA50 is larger, but on the other hand has a larger rubberized focusing ring.

both are *relativly* slow to focus and have long focus throws, when in the dark both will hunt like a drunken blind man in a desert, so neither really wins.

the FA43 is supposebly ultimatley sharper at F4.0...


is there a difference in contrast? yes, but i would not at any point say if its better or worse, its just different

3D look? the FA50 can make images pop out just as much as the FA43

FA50 has F1.4, while soft, its still there, and usable!

colour rendition? i dont bother with this one since its digital and people will screw around with the white balance after anyway

FA43 has more shock factor, its a limited after all (still kicking myself for not getting the silver one)

FA50 just looks better with the huge glass element (about half a n inch wider than the 43!!!)

bokeh? man if you can honestly sit there and tell me with a straight face that you can tell the difference?? whatever..




so.... if you have the 43, dont bother with the 50 and if you have the 50, dont bother with the 43 because you'll be chasing something only detectable on a 1x1 pixel level

as for the other shit, user error, making things look 3D is a factor of DOF, angle at which your shooting and your subject matter.

i want to see soemone make a pciture of a brick wall look 3D..


there, that is my non scientific comparison of the two lenses

now to decide if i sell one....

Thanks, I figured as much.

Just out of curiosity, for the same scene, which one's JPEGs are larger?

50 1.4 43 1.9
43 2.0 50 2.0
50 1.8 50 1.6




i mean, the difference is there, but these were just quick snapshots, not even controlled experiments.

because as we all know, in controlled environments even point and shoots can be made to shoot stellar SLR competative pictures

The funny thing about boy toys... erm, cognoscenti objects... is how much we're willing to pay for increasingly small differences - but once seen, we KNOW they are there, LOL!

and the problem is that the differences are not even determinant of good and bad! just that, different.

LOL we're on dangerous ground here... heh heh... with all that, I do feel my 43 is better in many situations than any 50 I have around, and I don't regret getting it instead of the af 50 or 35. Perhaps it was planning: this way I can indulge in bottom feeding the 35's and 50's.

The 43 has better flare/haze performance, though it does get a green halo inside the lens in the dark when there's a light in the frame.

Have you done any infinity/landscape tests? I'd like to see if there's a noticeable difference in resolution there.

EDIT:

In light of the above, let me rephrase:


Gooshin, you bastard, Have you done any infinity/landscape tests? I'd like to see if there's a noticeable difference in resolution there.

Good work Gooshin. Very useful. A lot of us have one or the other and are always doubtful what if I had gotten the other one. Now we know there differences are very small, if any.

One observation I have is that in the 43mm shots there is a lot more detail in the wall behind. So I think the DOF distribution in front and behind the subject is a little different between the two lenses. I don't know if that makes any difference. Just thought I mention it.

thanks for doing tests gooshin, always helps. out of all the photos, i liked 43 1.9 the best due to ... colour and contrast. i know your philosophy is towards more PP, mines is to the least as required.
i like the smaller size of the FA43 personally and i'm going to ditch my 50 just due to lack of use
in terms of bokeh, the FA43 is usually said to have rough bokeh and i do remember seeing some samples but don't remember in what situation it arises

The bokeh thing I think is when there are highlights at a certain distance zone with the 43.
