I'm still debating whether there is real difference between the Irix on APS-C and my Sigma 8-16mm set to approximately the same zoom setting and I think I can see better corner detail, less smearing and better contrast but unsure. Anyway, the fact I can use the Irix on my full-frame K-1 where I don't have anything close to that angle of view on FF means I won't be sending it back. It is now my preciousss!
Hey all so while digging through stuff today I finally found my camera from highschool, while it is not a Pentax it is a K mount so I hope I am welcome here. My mom gave me this camera (vivitar v335) in the late 90s-early 00's and I used it pretty heavily for skateboard and concerts but then when I got out of school it got put away and forgotten about, fast forward 20 years and I spend a lot of time behind a digital camera and have been thinking about picking back up some film. Right now I have the 35-70MM that the camera came with and while it is fine I am thinking about getting a prime for it but I am not sure what I want. Since this is a K mount I was hoping I could get some suggestions from here, if this is not the best place let me know. I am going on a cross country trip for 30 days this summer and I think it would be cool to take this along. I was thinking something like a 50mm or 135mm prime since they both can be found under $100, but am open to other suggestions.
Inherited it from a distant relative from another country, I'm amazed at how it is still working perfectly fine ! Definitely my favorite film camera, it is such a pleasure to use, especially with the Super Takumar 55mm. Asahi Pentax engineers knew what they were doing back then !
Is there a possibility to adjust the camera infinity focus? My K20d has been a bit problematic as it needs the focus to be set over the infinity in order the image to be in focus (see pic. 2). With AF lenses it is usually manageable but like the M40/2.8 in the image really can't focus to infinity in this body. What could be the cause and can it be adjusted?
And I’m absolutely in love with it!
Thinking I ought to invest in the 150-300.
ETA: holy crap, I exported the files at max 2048 pixels wide and reddit STILL murdered the detail. These are all sharp. Is there a trick to this?!
So the good news is that this lens is an absolute stunner in terms of optical performance both on my full-frame K-1 Mark II as well as on my full-spectrum converted K-3 with an STC 720nm clip-in filter.
Found a Pentax LCP correction profile for it on the Irix website which ChatGPT converted to a Lensfun Calibration file. I shot some stupid testshots right after getting this lens which was a steal as it was a demo model at my favorite camera store (CameraNu in the Netherlands).
Sharpness for such a wide lens across the frame is quite amazing and the lack of any noticeable hot spot in infrared is a relief. Even in IR, edges and corners don't degrade into mush nor does stuff in the background like with the Sigma 8-16mm.
So...what's the bummer? Sticky aperture lever causes wrong exposures. I noticed in while shooting, initially though it was an incompatibility with the latest Pentax firmware corrected by Irix in late 2024 but when I unmounted the lens and moved the aperture actuator to it's wide open position it either returned slow or not at all to minimum aperture. The store is decent though so I receive a free drop-off label with 15 minutes of me calling them. I ordered a new one which will be delivered tomorrow so my only problem now is impatience. The difference in price was unbelievably low; I paid €279 for the demo version but they were on sale now so only €404 for a new, sealed, lens.
Apologies for the sorely lacking test shots but the lens is on its way back via PostNL already. I thought of some tests I could run such as setting the Sigma between its 10mm and 12mm markings and shoot an aperture series on the tripod, minimally processed, as the control. Then, careful lifting the camera off without moving the tripod and then replacing the Sigma with the Irix. Can't change lenses while still on tripod because of the clip-in filter.
To be continued...
I press the shutter once and it goes up, but then the second press gets the mirror down and the film roller works at the same time so I’m not sure what the verdict would be. My boss gave this to me for free and have no other issues with it, exposure meter works good, shutter wheel, shutter count all work. I don’t mind having to press the shutter twice for the picture to take but I wanna know if the pictures would even come out in the first place before I buy a roll of film.
I have this old companion that I purchased originally to support K10d in high-iso and manual focus lens usage (split screen installed). What is the easiest way to get the body to power on more reliably? I think the supercapacitor/cell helping the power-on is no more with us and the body can only be started by starting it multiple times with fresh quality batteries. What can one do? Don't really want to disassemble the thing. Could a cap be soldered within the battery compartment?
I love shooting Pentax. I have used until I used up my K10, K5, KP, and last fall I bought myself a new body - KF.
It's first outing was a trip to Europe, it was fine for the first week, but then one day I checked and all of the photos I had taken that day (over 100) were missing. They were just not on the card at all. I assumed the card was bad and replaced the card, and it didn't happen again.
Fast forward 3 months and it happened again. This time I noticed with just a couple of missed images and again changed the card.
I started looking online for anyone else having this issue, with no luck.
I installed new firmware from Pentax and hoped that would have fixed it, but it happened again this weekend, and I didn't notice until this morning, so in the middle of the day Saturday for about 50 photos, they are just not recorded on the card. The file names of the photos jump from 613-659. I know I took the photos it was a very important part of the day and nothing you can "re-take" but I just have nothing to show for it.
I don't understand at all. I have never run into anything like it in the 2 decades I have been shooting with Pentax. Does anyone have advice or suggestions, or do I just need to accept that I have a lemon and it needs to be repaired or replaced?
Curious about ttartisan 75mm f1.5 (m42) for a while so bought it and it just arrived. Will see how well it goes.
Photo was with Godox IM30. Man, I never put tt350p on after I got IM30, so tiny and fun

Still seriously loving the look of TMax pushed. Definitely need to shoot it more, love the way it renders light
It's not the greatest of lenses for IR although I'm just teasing it a bit since I got the STC clip-in filter. These were mostly shot at the wide end (8mm) and at a reasonable aperture (f6.3) which avoids the worst effects of diffraction and is not wide-open. Results are a bit soft except for the centre of the image. I'm getting the Irix 11mm tomorrow and will see how it compares to the Sigma.
After many years, my KS1 got this issue. I thought it was lens related, as I only have one modern lens and the others are all full manual, but I found out my sigma 17-50 is fine. I bought a full manual wide angle (samyang 16mm) so that issue is solved, but I was wondering whether it's worth considering an upgrade to the KF. It costs 900€ where I live, and apart from this failure my KS1 is fine. What would be the pros of changing body?
All photos taken with Pentax 17. I'm only a hobbyist, usually don't work with film, and prefer to keep things minimal (don't like carrying lots of kit with me). I have a Fuji XT5 and debating whether it's worth keeping the Pentax I picked up cheap to snap these on, given Fuji cameras offer film simulations.
Film users: what is it about analog photography you love? What am I missing, and would I regret selling this camera? Its silly but I'm feeling really lost.
