Seeing as I might shoot it a lot wide open... just how bad is it? especially compare to the likes of my pancake lens (since most pancakes are pretty consistant from wide to stopped down)
With great selection of scenes, the lens certainly shines like any other lens. When the circumstance is not ideal for wide open shots, you would be careful with neutral/harsh bokeh and occasional erractic auto-exposure. Sigma 30mm f1.4 does hunt its autofocus in medium to low light environment as Dennis has mentioned previously. To me, it is not as bad as my other primes like fa 43 or 31 ltd.

I sold my sigma 30/1.4 because it was for my canon mount APC camera before. otherwise, this is a lens I go for because it is well built, less boutique as limiteds and I can allow myself to be less careful with lens handling.

Definitely no concern with sharpness in the center. Before I bought this lens, the reviews on line had all sorts of MTF readings which are not helpful to translate these findings into real life images. I find images quite pleasant regardless what the testing parameters are like.

but isnt that simply a matter of contrast (user adjustable) and depth of field?

take any lens that can go to F2.0 or less, pick a nice subject matter and viola, you get 3d pop.
The 43 pops even when stopped down.

LBA : Pentax 40mm/2.8 Ltd or Pentax 43mm/1.9ltd or Voigtlander SL-II 40/2

Hi,

I already own the FA 50/1.4 and the K50/1.7, so I know this question is a pure LBA, but I'm lurking on the Voigtlander 40/2, so I would like to know how it compares to its 2 Pentax competitors.

Guillaume

(And yes, I know it would be more coherent to buy a 35macro or the 31ltd, I just plan it later on)

This is discussed a few times and look at Blende's post when he tried to convince everyone how good ultron 40mm f2 is.


Da 40/2.8 vs Fa 43 vs Ultron 40 f2

Not sure where he has been up to these days but this is his excellent comparison

I believe all very similar optically, very similar designs, I would look at it as

if you like to manual focus then the ultron
if you want small then the da
if you want af and ff compatibility the fa (or if want a silver lens?)

I heard that he is still in German SLR forum.

He had a few unpleasant exchanges of words here.

Thanks,

I believe I was fooled by the search engine of the forum, next time I'll google it. Looking at the comparison, it confirmed to me that the Nokton is an excellent lens that compares well with Pentax primes.

Bokeh wise, do you know who win the fight ?

Wow, I'm so looking forward to strapping on my 43mm Ltd to my newly acquired used K10D (sitting at a friend's house right now). I was thinking maybe the 50mm f1.4 might be a nice addition but perhaps not!

Wide open at f1.9, no pp.

Have all three "pancakes" wouldn't trade them for any other lenses. Just got the DA 70 which was $200 cheaper than the 77-that's almost enough to buy the DA 40.

Please click the link.....

LINK: PENTAX FA 43/1.9 Limited
I don't know, if this was intended, but in that link the amethyst-picture of the Tessar beats the hell out of the Pentax! Both versions!
Is it really, that the Contax Tessar is that damn good, or is it, that the both Pentaxes are that bad focussed?

It was reported by some Taiwanees ...
There were some similar talks on the FA77 as well (series number smaller than 7000 is old version).

These are not my opinion or experience but what those guys found. To be honest, I don't really know if this is true. But Pentax does have more QC issues nowadays than they used to have. I guess it's true to most camera or lenses manufacturers.
I read the original post many months ago but imho, they are just someone's fantasy. The pictures they chose had different focus, and so to different bokeh of course. There could be different production batches with different details, but I have never seen any pictures that show their different characteristic being claimed. The only thing for certain is that Pentax have the history of revising their cameras and lenses quietly. Different fonts, different coatings, and some inner parts etc.

(1) Looks like a focus error to me (see defocused specular highlights in foreground)

(2) How the heck do you mount a contax lens to a K100D, anyway?
