The first post was AF portrait lenses. It seems like full frame digital is the body. The AF version of the 90 2.5 seems worth considering. Also one of the 70-200 2.8 zooms would be useful.

If you look at the optical formula for the M 40 as well as the DA 40 XS and DA 40 Ltd, they're 5 element / 4 group designs. I believe the arrangement is basically a Tessar + a correcting element. I don't know if there was a white paper published by the lens designers to explain their goals or anything like that with the design. Agreed on the 90 f2.5; I picked one up for an M42 screwmount kit and ended up just leaving the k-mount on it. It's a nice lens.

When I went looking for a k-mount 35mm f2.0 lens, based on samples and reviews, I picked the K-series 35mm f2.0. I think it's a touch sharper in the center than the M-series 35mm f2.0 wide open. The out-of-focus rendering seems more like the older Takumar lenses than the M's, A's, and so on. The M-series lens is quite a bit smaller, though, which may be of some benefit to you. Between the 35mm f2.8 and f2.0's from the M-series, I think at f2.8 they're about equally sharp. There are other people here with more first-person knowledge than myself. I do think that, with Pentax lenses anyway, at 35mm you can't really go wrong (save for possibly the DA 35mm f2.4 which doesn't really apply here anyway).

Welcome to the forum and good luck with your LX. They seem very nice.


I've got an M 40 f2.8 and I don't find it to be all that great. I prefer my M 35 f2.8. It's quite small but big enough to actually focus easily; the 40's focus ring is super thin to the point that it's not so easy to use. The 40 also isn't that sharp wide open; it's happy at f5.6 or 8 but wider than that isn't so great. I've never owned or used one, so take this next bit with a bit of salt; I'm not that impressed by what I've seen of the FA 43. It is tiny, fast, well made... but the out of focus rendering is often busy if given the chance based on the background. And I don't think it's so great wide open, either, although it sharpens up quickly just a stop or two down from f1.9. The only other lens I could really see competing for your interest here that came in native k-mount is the Voigtlander 40mm f2.0 Ultron but those haven't been sold new for some time and are not common or inexpensive.


The M 20 f4 is quite nice and there are folks using it on today's K-1/K-1 II digital cameras with great resulting images. Nothing really comes to mind that performs as well for the size of the lens. I've got a Tamron Adaptall 17mm f3.5 that is pretty nice but needs stopping down to really perform well. That lens has its own odd caveats though. The Samyang 14mm f2.8 is also pretty nice but really large and sometimes just too wide. There's a number of manual ultra-wide options on the market today for k-mount cameras.

Favorite film for low light photos with Pentax manual SLRs?

I think that you have to ask the 'what film' question while also asking what developer and development scheme is also preferred.

I want to play more with Ultrafine Extreme 400 and Clayton F76+ and pushing for two to three stops using fairly traditional development, stretched to get the push. I also like what I've seen a using Tri-X and HC-110, stand developed, shown here; Pushing Kodak Tri-X to 6400 and Beyond (Film Developing)

I can't really understand folks saying that they like Ultramax 400 for low light. It's a 400ish ISO film, sure, but get the exposure a bit off and it really falls apart in my opinion. Portra 400 is pretty great in comparison on this one but noticeably more costly per roll. Fuji Superia 400 is my pick for a good compromise if you want color film.

Lens suggestion for a parade and rally
Posted By pres589
Replies: 10

Unless the parade takes place in very cloudy conditions, you don't need the f-stop advantage of the 50-135. So I would take the above advice and go with the 18-135 on the camera + the 55-300 in your bag. Where you end up being placed relative to the street and people in the parade and such will help determine which lens you use.


My two cents.

hadi, if you want to deal with manual focus, the Samyang 135mm f2 is supposed to be a very good lens. Understood if you don't want an MF-only lens for your DSLR; I generally don't like using them on my DSLR. Agreed that this seems like a bad place to be missing a lens. The old F 135mm f2.8 is supposed to be quite nice although it's not as fast as you're asking for.

Depth of Field Preview is apparently an assignable function of the Fx3 button. I say this based on a quick internet search; I do not own a KP and don't know what it's like to assign this function and if it allows for exposure "needle reading".

Favorite cheap film?

I think there's actually some push-ability with Foma 400, but it's probably going to require some semi-stand development work with XTOL, Rodinal, or HC-110 for best results. I've had okay results with my Clayton F76+ pushing efforts here but there's a lot to be desired, with shadows falling off into base layer and thin negatives and so on.


I had a roll that I metered to ISO 200 and cut the development time by 15%. The negatives had good tonality and nothing disappeared into the base fog of the emulsion. Foma 400 pulled a stop is nothing to sneeze at.

Foma 400 Action is nice if you rate it at ISO 200 or 250. It doesn't seem to be a true 400 ISO film. It's okay there but the grain comes out.
Fuji Superia 400 is, I believe, better overall than Ultramax 400. Both are about as cheap as it gets for 400 ISO color film unless there's a random sale on something expired.
I've only shot one roll of it so far but I really like what I saw with Ultrafine Extreme 400 and want to really get to know that film. It reminds me a bit like Tri-X 400. Where that film is sourced from, what film it is similar to, etc is not at all clear.

I think I've shot a single roll of Kentmere 400 and that was well before I was doing my own development. Therefore, I can't speak to UE 400 == Kentmere 400, although I have also noticed that equivalence discussed online. If Kentmere 400 is a flat-drying, low contrast film, then I don't think this is that. Mine dried curled *the long way*, like it came out of the cassette with a bend in it, vs. curled over the short way which makes some films harder to scan (Ultramax 400, I'm looking at you here). I don't think I would describe the UE 400 roll I developed as having high contrast, but I don't know if low contrast is where I would put it, either. Middle contrast? Is that a term?

I thought this was interesting; I like this guy's film reviews: Film Review Blog No. 34 – Ultrafine Extreme 400 – Alex Luyckx | Blog

I can take a photo of the edge markings if anyone is interested to try and determine if this is some rebranded stock. It says it's Ultrafine 400 from memory and nothing about Harman, Ilford, Kodak, etc etc.


I don't know how close L-110 really is to HC-110. It may be "close enough" but I'm really interested in HC-110 for pushing via stand development. That might take things well beyond the similarity of these two developers. Looking back, I should have done more reading about how to determine if a developer will be useful for stand development, and if F76 would have worked there as well, but there's a *ton* of information to sort through to figure this stuff out and it starts going over my head pretty badly.

This was the first time I played with the stuff. I basically treated it like Tri-X 400 from a dev standpoint. I would really like to have more time with it, in different settings, but so far this role looks really good to me. Good contrast vs. tonality compromise, just enough grain to look like film, seems pretty push-able, etc. Curious how it would do with some extreme pushing stand development in HC-110. I'm optimistic that it would respond nearly as well as Tri-X 400.

Ever shot Ultrafine Extreme 400? Ever developed it... in Clayton F76+??

I believe these were both metered to ISO 800. They were developed with a roll that was metered to multiple speeds. 1+9 dilution, 16.5 minutes total soup time, 45 seconds initial agitation and two inversions every 30 seconds after initial. I really like the way these came out. Why this film isn't talked about more, I do not know, but here we are;





I'd like to shoot the daylights out of this combination for a while but I'm about to move across the country and I need to stop developing film basically today so that will have to wait a while. There were other shots on the roll that I metered to EI 1600 and they came out great. I feel like this is one of those times where the film and F76 could actually push to EI 3200.

Tamron 28-105 f2.8 AF and Not the Adaptall version?

The lens in question is very much a product of the 90's. Agreed on its age. That said, the reviews I found of it seem quite positive, even on cameras like my K-5 II. Here's a review with a number of sample photos;

Better Family Photos: Do It All at f/2.8: the Tamron 28-105 2.8

It doesn't seem perfect. I think I'm probably better suited by going with the Tammy 28-75 that is still available new and zooming with my feet if I need to.

Primes to replace would be my Sigma 28 f1.8, Pentax F 50 1.7, and then, uh... I guess a 100mm Macro as we're sort of limited for options here. Canon's old 100mm f2 seems nice...

While I'm quite aware that I'm far from the world's best photographer, I'd like to think that I've got enough credit around here to understand the different pro's and con's in comparing zooms and primes. I mean, yeah, I could carry a pair of primes and pretend that I've actually got the world's least convenient zoom in my hands instead, but that's not the goal I had in mind. I actually do that quite often; a 28 and a 50 often leave with me when I go out with a film camera.

The lens I asked about isn't available in k-mount. Thanks. We can all go home now.

Both Sigma and Tamron had 17-35mm variable aperture zooms available in k-mount, with AF, for a time. I never see them discussed. I believe they review decently. Might be worth considering.

The Pentax M 20 f4 is quite nice to use for landscapes. Northcoast Greg gets some amazing shots with his on his K-1.

I love a good 28 but I can't see a reason to go with that lens considering what you already have. I don't think the Mini-Wide is all that great; it's alright but it's nothing to crow about. I really like my M-series 28mm f2.8 mk2 (non-chromed snout) and I believe it's in another league beyond the Mini-Wide.

Yeah, same, doesn't seem like it is a legit K-mount product. Seems like I'm probably better off with the existing k-mount Tamron 28-75. Seems odd that this lens's basic spec's of 28 to 105mm and constant f2.8 wasn't replicated elsewhere. The Pentax 50-135 seems great but it's longer on the wide end than I think I would want. The only other lens I've found that would give me the reach/FoV that I think I'd want is the old Tokina 28-80 f2.8 but that lens doesn't really review that well. The Pentax/Tamron 24-70 f2.8 seems very good but I'd rather have the 75 on the long end. Etc etc etc.


I shot portraits a few days ago with a friend's Canon 5D and 24-105 f4 and thought that was pretty great and it got me thinking about how I might want to get more involved with photography after I move in a couple of weeks.


Thanks for the replies.

Controversial X-pro 3 screen

I think the camera would have made more sense if there were a couple of display modes to let the user turn the screen off, show minimal information with the film emulation mode being applied (and Fuji should license other film emulation types either from DxO, Kodak, etc) along with basic ISO, exposure, etc, or else a fully functional 'all the mod-cons' screen type. And then make it fixed so that the back can be made more slim and the hardware more reliable with fewer possible weak points in the hinge, cabling, etc.

I really like the control layout as shown online. If I really get feeling sassy I might rent one just to see what it's like to use for a weekend out walking. The lens selection for these cameras is probably the biggest weak spot I can see.

Does this lens actually exist in k-mount? This was one of those transition products where Tamron was moving away from Adaptall lenses and had the same version in both native-mount and Adaptall. I've only seen online in my limited search mention/examples of the Adaptall version, none in real k-mount.

The reason I ask about it is that it seems like an excellent do-all portraits zoom on crop. I know it's large by heavy, the front element is huge, they're old at this point, and obviously rare. The only other lens that really makes sense to me is the Tamron 28-75 that you can buy new today but the added reach seems worth it.


Does anyone have one of these? Of is this one of those times where k-mount land didn't get the real deal.

I used the word "parts" because I didn't want to use the word "kit". I thought Shelby American had some similar agreement with Superformance as well. I didn't know that Kirham was so involved with Shelby American as well.

I had thoughts about a Factory Five replica but without the side pipes and probably something other than a V8 under the hood. Never got even close to pulling the trigger on that one and at this point I doubt it would ever happen for me.
