HD DA 21mm Ltd Lens Not Sharp Enough, or Just My Focusing Error?

By f/11-16 you may be running into softness through diffraction. Also, for what it's worth, when I first got my DA21, it did front focus dreadfully. It was fixed finally by Pentax - this was years ago before micro-focus adjustment was available on the cameras.

what has been your most "disappointing" lens?

DA55-300 x 2
The first one (metal mount) was clearly, visibly, obviously defective. It was sent back to Pentax in Tokyo and came back worse. It was re-sent back, and declared to be 'within spec'. Well, if it was within spec, Pentax thoroughly deserved all the uncertainties that surrounded its fate at the time.
The second one I got as an act of misguided faith, with the plastic mount, is better, but noticeably decentred at various focal lengths.

So I gave up, and get much better results with my M manuals, notably 100/2.8, 150/3.6, and even the much despised 200/4. So to hell with the 55-300s, both of them.

Actually the worst lens I EVER had was the cheapo Sigma 18-50, available a decade or so ago. That really was a stinker, although hailed at the time as a worthy alternative to the mediocre FAJ 18-35 that Pentax were offering as a kit lens for the *istD. Oddly the Sigma 50-200 that went with it was quite good, albeit a bit heavy.

I don't think the 1.4 is as bad wide open as some say - the key is to get the focus right. The 1.7 has a bit more contrast wide open, but the difference is not night-and-day. Once stopped down a bit, I find the 1.4 superior, certainly at the edges.

This is all quibbling. They are both excellent for what one would use them for - and I use the M 50 1.7 regularly with an adaptor on my M4/3 GX7. Very nice.

It's ages since I last contributed anything to the forum, so it's time I did something about it. Here's couple a with the K SMC 105 f/2,8. I really like this lens, although it is quite dreamy wide open, and liable to produce serious fringing on very high contrast edges unless stopped down. (On the first of these shots I had to neutralise a pretty obvious fringe along the top of the upper flower. Now I notice that the lower flower could have done with the same treatment.) Close it down to f.5.6 or more and it's very sharp. The bokeh is nicer than I remember - it has been sitting in my dry cabinet for a couple of years, sadly neglected. My acquisition of a Panny GX7, with an adaptor, live view and focus peaking has re-energised my interest in these old lenses. Now I get easier focus and aperture priority automatic exposure.

Incidentally this is the actual lens that's illustrated in the lens database, the one on the left.

50mm comparison - f1.7 vs f1.4
Posted By timo
Replies: 22
Views: 3,856
I have had a variety of M and FA 50s over the years, and my impression has been that the 1.4 is just as sharp as the 1.7 at equivalent wide settings, but has lower contrast wide open; and that stopped down the corners of the 1.4 are very slightly better. But the differences are tiny, and I am not going to waste more of my life doing more comparisons! I'm sure some of the comments on the 1.4's alleged softness wide open are down to the difficulty of getting the focus spot-on with such a shallow DOF.

Refreshing to see a 'new' perspective on Istanbul. Superb shot - and nice to see the M150 get some appreciation. I think it's a very good lens.

I have both and I have never been able to see any significant difference between them. So the M version wins in practice because it's less of a pain to carry around.

HD DA15 Limited sharpness

I often find wide-angle lenses rather unreliable in focusing - my DA15 is unpredictable in sharpness terms, and I suspect focusing must be the reason (despite the huge depth of focus field you should get with that lens).

Is this normal sharpness for the SMC 40mm Limited?

The complete shots are too small to tell here; the third one (the detail) is not focused on this bit of the image. The bubbly things are just out-of-focus highlights - this lens is not a great bokeh-creator. Can't really tell if the lens is at fault from these samples. I have a DA40, and while I find the focal length a bit strange, it performs very solidly.

Well that's one answer! But I don't wear progressives - had them a long time ago, but the 'in focus' zones never seemed to match up for the two eyes. Lousy supplier maybe.

From what you have I would take the 18-55 and 50-135.

From what I have, if travelling with other people I would take 18-55 and 50-200. Or maybe FA 24-90 + DA15 + 50-200. If travelling alone probably DA15 or DA21 + M28/3.5 + DA70 + M150.

Don't use primes if travelling with others and you want to be on speaking terms at dinner.

But Michaelina the Q is no damn good if you need reading glasses and can't see the screen. Why Pentax did not offer an EVF option (same with K01) I will never know. It would have increased sales massively to anyone over 45.

It focused on the trees. Not the camera's fault, and probably no need to adjust the focus calibration. Often happens with wide-angle shots where it's hard to control exactly where the focus point is going to end up.

My experience with lens repairs is very patchy - if you are not sure about the guy you entrust your lens to, it may not be worth spending the money.

In your position I would buy an M28/3.5 (really nice lens in my experience, not expensive), and see how you get on. That FL is incredibly versatile on APS-C.
