Originally posted by bsamcash I am chiefly a prime shooter. Early in the year my choice selections were the Sigma 30/1.4, the DA 35/2.4, and the DA 40/2.8 Limited. As you can see, I have quite an overlap Throughout the normal range. Nevertheless, they all had their strengths and weaknesses: the Sigma was contrasty and fast with beautiful bokeh, but distorted and was extremely soft; the DA 35 had a perfect field of view and was insanely sharp, but the build quality was questionable and the autofocus made it unusable in quite settings; lastly, the DA 40 was stealthy and jewel-like, but the lack of micro contrast left the images flat. Needless to say, while my kit excelled in some areas, each lens had an annoying fault.
My favorite of these three was the DA 35/2.4. It was my choice everyday street and normal portrait lens. But its major issue, the build quality, made my fears a reality when it just broke. The autofocus just stopped working, and I never figured out why. The ring became oddly stiff to the point where even manual focusing would not be possible without fear of breaking it further.
Because of this, I decided it was time to sell these three lenses and replace them with one all-purpose lens. The lens I chose was the Japanese FA 43/1.9 Limited. And here is my experience after about six months. I know another option is the DA 35/2.8 Limited, and it does look fabulous, but it goes for even more than the 43, and that's just too much for a hobbyist.
First thing's first: this lens is absolutely gorgeous. And even more beautiful on my MX. I thought the build quality of the DA 40 was good, but the 43 is even better than I remember my M 50/1.4 being. The set of screws on the underside are a little odd though. Even the dampening of the focusing ring feels better (albeit slightly looser). The balance between auto and manual focusing of the throw is perfect; it's fast on my K-5IIs, but accurate on my MX.
What about image quality? Here's the troubling part. Don't get me wrong, it is easily the sharpest of all the lenses mentioned. Tack sharp at the center wide open, and the corners look great at 2.8, but that's from real world use, I've never used a chart or anything. The problem is, however, is it is just not that much better than the DA 35/2.4 at the same apertures. Not even the bokeh. The sharpness and micro contrast are similar enough, plus, the 35 has the benefit of that perfect field of view (on the K-5IIs). Although, overall contrast easily goes to the 43.
As far as color accuracy, the 43 cannot touch the 35, which is the most neutral of all the lenses, but whether or not that is a good thing is very subjective. It may be my imagination, but oddly the 43 seems cool at wide apertures, but warmer when stopped down. But this is not something I have actually tested for, just an observation. I keep a hood on it, so I don't really experience any flares or ghosting.
Lastly, I would like to bring up the focal length again. It is something magical on my MX. It's as if there's no camera there. But it's very strange on APS-C; it's hard to visualize and get used to. I'm not sure what I was expecting, as my range before was all wider, but when I'm using my F 35-70, I often find myself going for reach, so I figured it would be a great middle ground. But it's not. It's weird.
So, after all this do I like this lens? Yes, I guess. Optically, it's great, if slightly overrated. It is definitely not the end-all-be-all prime I was expecting (at least not for digital). And I may make some enemies, but I feel it may have been a better idea to save the money and just buy another DA 35/2.4. But does this mean I'll sell it? Hell no! At least not unless I'm desperate. It is too perfect of a match with my MX--I mean "Leica who?" good.
So those are my very unscientific thoughts on the FA 43/1.9 Limited. What are your's?
Reading through your post, it seems to me that one of your key issues is FOV. That's a matter of personal taste and one's usage requirements of course - nothing to do with the lens itself.
There being no Pentax FF DSLR at the present time, if FOV is a critical factor for you, then this lens may not be the most suitable for your requirements. Having said that, it harmonises perfectly with your MX, so it is useful there; and with the appearance of the FF DSLR you may find much usage for the 43.
Indeed, I believe part of the reason for the popularity of the FA31 is simply because in APS-C it works out to normal focal length. In a situation where the FF DSLR were available, the situation may be altered, with the 43 seeing an increase in demand since it would be the normal lens then.
(I however love the 43's effective focal length in APS-C - it works great for my photographic needs/taste.)
I wouldn't call the FA43 overrated. Many who feel that way, say that perhaps because it did not match their expectation. But one needs to appreciate that here is a lens with a very specific rendering character, which in the right situations, and in the hands of a photographer who understands well the lens, can create utter magic. One can read through the forums and this point should be quite clear. Personally, I have shots taken with it which NOTHING else could have done - not even the FA77! Mind you, that's not a knock on the 77 at all - I use that lens too - amazing! It's just that I recognise the respective strengths of both lenses, and use them accordingly.
The other thing is, looking at the other lenses you mentioned, I suspect that part of your problem might be arising from the fact that the 43 is a lens that behaves and renders very differently than those other lenses which you mentioned, which you were more familiar with, and thus may not match what you expected (familiarity is a major factor). Perhaps with time and increased usage of the 43, you may begin to understand and like what this lens does. The 43 is a lens that is not understood primarily in terms of technical parameters (though they are important, of course). Rather, this lens has a character, a "soul" to it, as it were. One thinks of it more in terms of an artistic tool - like a fine, hand-crafted guitar, say; with a behaviour that needs to be learnt and mastered to yield what it is truly capable of - and that is nothing short of sheer, gorgeous magic.
