Originally posted by Eye.n.Eye This lens is an excellent combination of cost, size and sharpness.
However, I think any discussion of this lens should note its Achilles heel, its susceptibility to shutter shock on the K1. The worst speed is 1/100, where it has the most shutter shock of any lens I've ever tested. To avoid it completely I skip the range of 1/40 to 1/320.
If you always carry a tripod and can use electronic shutter its a non-issue, but as a day time walk-around lens, I've always found this a frustrating limitation. Its a shame, because its optical performance is genuinely impressive for its size and cost.
Hmmmmm....I have not noticed that, but to be fair, I am primarily photographing at shutter speeds of 2-3 minutes in length. But when I have photographed "normally" during the day, I haven't noticed that. I'll keep a look out for it, though, thanks.

A cheap lense for me is under $35😁
Hahahaha! Well, that's basically paying for postage!!
I feel like for what you get, it's a pretty great bargain....especially on the used market. And with the exception of a few Lensbaby lenses and some oddball used macros, it's the least expensive lens I have, so I'm rather pleased at how much use it gets for having paid about $300 used for it.

Good article and excellent images.
Thanks! I feel like it's a great value for the money, even new.

Originally posted by Michail_P Some excellent photos from a surely valued lens. The 28-105 range is the perfect walk around companion.
It really is a great size, weight, and focal length for a "walkabout" lens. And then the image quality is excellent. I am super happy with it, and just got back from two nights of long exposure night photography in which I used this lens extensively along with some fisheye.

Originally posted by Paul the Sunman I think you are underselling the 28-105 somewhat. You don't have to align all the stars to get good performance. During the pre-shipping phase of the original K1, Ricoh was putting out a lot of sample pictures to show how good the camera was, and some of those were taken with the 28-105. They had confidence enough that it would show off the new camera to best advantage. And that is my judgement too. The variable maximum aperture is its only real "weakness", and for many of us that's a price we are very willing to pay for its relatively compact size and moderate weight. I don't feel I am compromising when I use it. Which of course is not to say that I don't value the special characteristics of the various primes within its range. There is a difference between a "walk around" zoom and a specialist prime. An apple is not a good orange, not matter how perfect it is.
And for a lot of us, the variable maximum aperture is not much of an issue if we are going to be photographing at f/8 all the time anyway. I was fanatical about using what is supposed to be my "best" lens for the job only to find that the 28-105mm is producing equally great images and is considerably more flexible. I'm really pleased with this lens, which is why I was inspired to write this article.
And, well, it's always good to write about Pentax whenever possible.

Originally posted by northcoastgreg I regard the DFA 28-105 as a kind of photographic secret weapon. It gives you professional or near professional image quality in a smaller package. As a landscape photographer, not only don't I need f2.8, I don't need f4 either, but if you're shooting with Nikon, Canon, or Sony and you want professional image quality for landscape photographer, you have to play north of $1,000 and put up with greater weight and size in a standard zoom. Can any of those fixed aperture lenses do better than the following images?
I don't know, but if one even has to engage in deep-level pixel peeping and still not be sure most of the time, then it probably doesn't matter anyway.
I do mostly night photography under a full moon with this lens, so I'm basically parked at f/8, f/9 anyway. And when I do day photography, it's mostly landscape, so again, f/8 mostly.
This lens is impressive, especially given the size, weight, weather sealing, and price.
