"Taking photographs is not a crime" ... in some jurisdictions!

I was looking for more information on this story, and just days before the incident at the beach, a sexual predator was sentenced for raping a teen after luring her to Jersey. I also stumbled across the Jersey investigations into child abuse in care homes, which began about 15 years ago and lasted to 2017 (the investigations, that is. The abuse spanned decades and involved hundred(s) of children). There appears to be some element of media hysteria (a "fragment of a child's skull" turned out to be coconut), but three men were eventually convicted of sex crimes. In this context, I think a bored tourist snapping women and girls with his phone at a Jersey beach could be considered "likely to cause a breach of the peace" more than it might at a different time or place.

K-x eating batteries fast

Could the camera have been off so long that it forgot the battery type? I vaguely remember a similar issue with a K-x and "known good" NiMH batteries, and IIRC it had reverted to auto-detect and was auto-detecting wrong.

Pentax k-50 - issue with Pentax 18-250 lens

I was going to suggest jiggling the zoom lock and/or twisting the zoom ring while holding the lens in different orientations to try to shake loose the whatever-it-is in the helical. The problem in swanlefitte's link (a loose screw) could be it. I have the Tamron-badged version of the 18-250, and have never had a problem, but I have had issues with loose screws in other Tamron lenses of that era.

Asahi Glass is a dozen years older than Asahi Optical; unless AOCo was a subsidary of AGC all along and Pentax lore has been hiding it, I don't think you can find a relationship. The one possibility I can think of is if AGC bought the filter manufacturing bits when Hoya broke up Pentax, but it seems unlikely Hoya would facilitate a major glass maker to start competing with one of their core businesses.

All black K-01?

Of course it's possible - anything assembled can be disassembled and reassembled - but getting the knobs off will require breaking glue bonds and may not go well. It would be cheaper and MUCH easier to just paint the parts. Also, having both, I can tell you that the black parts on the white/silver bodies have a smooth, bluish-black finish, while the yellow/black bodies have a textured finish that is a slightly "warmer" black. It's just different enough to look "wrong".

Painting it would also be following the tradition of Henri Cartier-Bresson, who painted the silver parts of his Leicas.

Reasons you love the K01 ?

Some found that the "terrible ergonomics" of the K-01 actually made it easier to operate with thick winter gloves on. I remember the first time I picked one up (it was actually a dummy display unit), my only negative thought on the ergonomics was "they should have swapped the red and green buttons". Other than that, I didn't really have a problem with it. Because I grew up with a film SLR, I wasn't locked into the all-the-controls on the fat-right-grip format.

The problem I *did* have was after I bought one and I tried to use it like a regular camera, with a neck strap, I realized that my eyes were no longer young and I couldn't hold it far enough away to focus properly. So I tried a wrist strap - and that is when I fell in love with the K-01, because I could just shoot from the end of my arm, whether it be high, or low, or off to the side. It opened up a lot of creative opportunities. With a DSLR, I tend to shoot from one viewpoint - six feet off the ground - because squatting or kneeling can be a hassle when there are crowds around (and/or because I am old and out of shape, whatever). Also, to get those shots with a DSLR, I have to put the camera in LiveView, flip the neckstrap over my head (probably knocking my hat off in the process), set up and take the shot, switch the camera back to viewfinder mode, and put the neckstrap back over my head (knocking my hat off again) -- either I will just decide the shot isn't worth the bother, or the opportunity will be gone before I get set up. Yes, shooting at the end of my arm means trying to frame the shot with the LCD at some near-unviewable angles, but you learn and adapt.

And being relatively small and light, I have no problem bolting a K-01 onto a travel-tripod and carrying the whole rig around shoulder-arms for things like Christmas lights. I'd hesitate to do that with a K-5/3/1.

Using a Metz Pentax flash at a museum

The vast majority of my picture-taking* over the years has been in museums, and while most are strict about flashes and tripods, train museums are usually an exception.
Aviation/aerospace museums are usually okay with flashes, too - with similar challenges due to the size of the subjects.

*I hesitate to call what I do "photography" :p

My issue with flashes in railroad museums is that the subjects are so large
(and usually painted dark colors) that if you use an on-camera flash, all you get is the nearest part with everything else lost in the dark. I would also lean towards a tripod, unless you can do off-camera flash with a wireless trigger.

Old flash new flash what's the issue?

In some older flashes, yes, the flash absolutely does pass 400 volts back through the camera. This is because all an SLR did to trigger the flash was close a metal contact in the camera, completing the circuit between the flash's capacitor and the strobe. Later flashes added electronics so that the trigger voltage did not have to be the full flash voltage. In either case, modern DSLRs have replaced the metal contact with a transistor, which may not be able to handle the trigger voltage.

This also partly answers the question of why are flashes so expensive compared to the good old days. We've gone from the only communication being a completed circuit to all sorts of settings negotiation between the camera and flash, in some cases wirelessly. You can still get a good manual flash for much less than a hundred bucks, if you shop carefully - but you will have to do more of the work that the expensive flashes do automatically.

Newbie lens question
Posted By THoog

Views: 816
Glad you figured it out! If the adapter ring is a genuine Pentax, then (1) congratulations - those are highly prized, and (2) you should be able to remove it just by inserting a fingernail in the notch, pulling the locking spring away from the mount, and gently twisting counter-clockwise. If it isn't a genuine Pentax, you will probably need a tool, but a small screwdriver should work. Some of the cheap 3rd-party adapter rings are machined so badly that they are hard to remove even with the tool, and the locking spring is worse than useless. For those, I usually clean up the machining with a file, remove and discard the spring, and try to avoid twisting the lens out of the mount when focusing.

Neither the aperture guard nor the Ricoh pin should have any effect on a manual-focus film camera like the Program Plus. Can you give us more detail on how the lens does not mount? Does the bayonet not insert all the way, or at all?

My broken Tamron SP 17-50mm F/2.8 XR Di II LD Aspherical [IF]

I think the answers have to be 'yes' and 'yes'. There are no K-mount lenses in the Tamron catalog, and Tamron has not introduced a new K-mount lens in years (unless you count Pentax-badged versions of some of their full-frame lenses). Their efforts appear to be pivoting towards mirrorless and full-frame.

The 17-50/2.8 "Workhorse" was introduced in 2008 - it is very unlikely they would still be making such an old design and just not listing it in their catalog.

P/K A lens wont fit my KM

It is meant for early 1980s Ricoh or Pentax auto-exposure manual-focus K-mount SLRs. Unfortunately, when Pentax implemented autofocus later on, they put the autofocus sprocket where Ricoh had put their auto-exposure data pin (the "Ricoh pin"), and the pin can catch on the sprocket hole, locking the lens in place. It isn't a problem for manual focus bodies, and some (but not all) lens makers used a rounded pin that doesn't catch. Most DSLR shooters remove the pin to be sure.

It looks like it might have the longer aperture arm shield that bumps into the SDM contacts. Some third-party lens have this, and you have to remove the shield or file/cut away the extra metal. This sounds a more dramatic than it is - I have done the mod in less than five minutes. There are a number of threads on the forum showing how to deal with this issue.

ML-60 for K200D?

The ML-60 fits the K-7/5/5ii/5iis/3/3ii/30/50/70/500/K-S1/K-S2/KP.

The K200D used the same screen as the K100D/K100D Super/K-m/x/r. I don't remember if Pentax made optional screens with lines for those bodies; I expect they would be pretty hard to find now, unless you went with a 3rd-party screen.

IIRC, image size in PTLens stays the same, unless you crop smaller to remove the black bulges that appear when you de-fish.

And just to throw some chaos into the original discussion, the ridges on the inner surfaces of the DA 10-17's built-in hood are exactly the right size/spacing to grip 58mm filter threads. Vignetting will be a problem.

For old glass with no/poor coatings, I found using the deepest hood I could find that did not vignette would help with the haze.

As to sharpness, while cheap 28mms are common as sparrows, sharp ones can be hard to find (by today's standards of sharpness).

I still prefer that 16MP sensor for shooting holiday lights and things like that. One quirk I can think of is a tendency to blow out on blue lights, especially blue LEDs.

For years, my preferred travel kit has been an ordinary backpack with a small camera bag (an old Tamrac superlight) holding my spare body and lenses, with the main body in a Lowepro toploader case and any teles in Op/Tech neoprene pouches. The toploader can serve as cushioning in the backpack, or I can attach the shoulder strap for a very light shoulder bag (or a ready-use pouch for a second lens). I've used various Op/Tech neoprene jackets for my camera bodies, but I really only do that for cushioning these days as the toploader is more flexible.
