Well, I would test it thoroughly before paying anything. It is not unheard of for ink jet print heads to dry out after long periods of disuse. Some are salvageable. Some never are. So, unless you are certain that it actually prints, I wouldn't buy it. I might take it for free. I might even be argued into paying $30 for it, but no more unless I've seen a perfectly usable photo print come out of it.

A printer data cable doesn't cost much. Odd that there is none there. That may be to avoid testing it.

That seems like an easy question to ask: Is it the bank robber's fault or the people who report the robbery? Is it the arsonist's fault or the people who watch the building burn?

A lapse in ethics belongs to the originator of the act, not the spectators.

We could set up an argument that the system is flawed, i.e., that the use of "likes" and "followers" and "views" is too closely tied to monetary reward to allow the adherence to an ethical standard. However, that's pretty easily applied to anything.

For example, the bank teller avoids embezzling even though the money is right there in his hands. That's more immediate than digital indicators. So, honesty and ethics seems to remain a quality of the individual, not the crowd.

Hello from Uruguay! Question About Pentax 67 1:4 55mm

Is there a face plate over the front lens element? I'm not sure about your lens, but: Many Pentax lenses have the front element accessible by unscrewing a metal plate (in other lenses, it is the name plate) that threads into the filter threads. The plate unscrews counter-clockwise. Some say anti-clockwise.

The usual tool for this is a rubber device of the appropriate diameter that fits over the metal ring but not the glass of the lens. Press hard and try to unscrew.

This page contains a number of rubber lens plate removal tools to give you an idea what they look like. They're widely available via eBay, Amazon, or BH, etc. You'll need to have the right diameter, exactly, to avoid touching the glass.

Look for "Lens Ring Tool:" Shop Camera Repair Tools at Micro-Tools | Micro-Tools

https://www.amazon.com/s?k=rubber+lens+slr+removal+tool

A different style, search for the size that might fit: https://www.amazon.com/Repair-Silicone-Rubber-Retaining-Scratch/dp/B00SUM0KHS

Lens cleaner that does not harm SMC or HD lens coatings: 2-butoxyethanol?

I also have been using ROR on regular lens tissue or Kimwipes for some time. It serves my purposes, on the occasions when a smudge or fingerprint must be removed from a lens or filter. I don't think it damages or wears the coating any worse than anything else. That's more in the pressure applied, I think.

I had some Crizal coated glasses, sold with the claim of "No Quibble scratch coverage, etc, etc" against a list of things. I came back a few months later with scratches and they said, oh that's too bad. Not guaranteed for that. What? Made no sense.

Well, the filter thread is 55mm, so that's the cap size you mentioned. It is roughly 4 1/2 inches long. Max diameter is roughly 2 1/2 inches.

The thing is, does it look like the lens you had? Did it have a roughly "normal view" to a "telephoto view" to the images you took? That's what the Tokina 60-120 would give you.

I know they didn't specifically mention a movable screen in the video, but the K-70, KP, and K-1 (& ii) have all been released with some form of movable, tilt-able, pivot-able, or articulated screen.

While it is pure speculation, it doesn't seem to make sense that Pentax would go back to a fixed screen for what they regard as their flagship APSC camera. If they can have a movable screen in the "lower end" K-70, why would they not have one in the K(new APSC)?

I suppose stranger things have happened, but it doesn't seem to me that they'd go backwards.

Possibly in favor of a fixed screen is the discussion about the OVF extending 3mm beyond the level of the screen. There's no visibility of a pivot screen, but maybe the model is dummied up to keep some secrets still?

Maybe it is just my wish list that is keeping the movable screen on the table ... in my mind. I just cannot see them dropping it after all recent releases have had one.

Hello Bonico,

Welcome to PentaxForums! Hope you find the place useful.

I don't have that particular lens so I cannot look at it to see what you are referring to. If the following links don't help, maybe making your own post with a photo of your lens would help draw attention to where the problem is or the ring without slots? People may not find your comment within this (older) post.


This is a similar lens, but maybe not assembled the same, I dunno: 200mm F4 Takumar Dissambly Guide - PentaxForums.com

This is a guide to the various lens repair / assembly guides that may help if there is one for a similar situation as you have:

Thank you for the technical explanation for me. Oh, yes, that's exactly what is going on. I suppose that I need to plan on lens replacement, but now we've got the crazy Covid thing going on. So it will wait and wait some while longer.

I'll be sure to ask for the color vision test D-15 when I finally do have an exam. Since my past ophthalmologist has retired (he's the same age as me), I'm looking for a new one. Cheers!

Even brand new off the shelf, there are a few dust particles visible inside a never used lens.

"Minor amount of dust" is basically a standard disclaimer, because dust is always present, yet some buyer may demand a return based on "dust" on a newish or "mint" lens.

I will be quite surprised if the "re-open" stage looks like flipping a light switch from dark to bright. It seems like everyone we know is extremely cautious and not at all anxious to run out and die.

The only people who can (possibly) believe they are safe are those who have had the illness, recovered, and are now believed to be immune. I say "possibly" because there are troubling reports of people weeks later testing positive again. We don't know if this is a lingering thing -- the way HIV hides out in obscure cells for example -- or the way that chicken pox hides out in the nerves only to reoccur years later as shingles -- or if it truly confers immunity. And then for how long? Life? A couple years?

The 2008-9 recession had the slowest economic recovery in modern history. But there was no illness killing people who ventured out too much or mixed too much in the population shopping, traveling, etc.

Aside from the basics needed for survival and a few feel-good items, I think most people will hold their money close for years now.

The only thing that would look like a bright light being switched on would be a truly effective vaccine, administered widely and quickly. Even the most optimistic don't see that happening for a year and more. It's even longer before billions of doses are created.

I hate to be so grim, but reality keeps knocking on the door day and night. Actually avoiding reality might be a good choice for me for a while....

Edited to add, from the evening news: 48% of Americans say they will not return to public life ("venture out") until the virus is "contained." We can all discuss, I suppose, what those terms technically mean and how strong the protection reflex will be...

Cheers! Everyone stay safe and stay healthy!

As a kid, I had no idea that I couldn't see well. How did I know what vision was like? In retrospect, I was sitting closer and closer to the TV from about 3rd grade on. A coach in 7th grade basketball noticed that I squinted really hard when I was shooting a basket. He talked to my parents. Glasses followed soon after. My grades and basketball both improved (not that great, I was still clumsy having grown a foot in a year...) :)

My ophthalmologist and I became good friends, having seen each other for over 20 years. We retired the same year too. After awhile, I told him, "I think I'm having trouble with my yellows when playing with post-processing for my photos." (He's a Nikon guy, but still a decent person).

He said, "You've always known when something wasn't right. You might be too perceptive for your own good. Be sure to bother your new ophthalmologist about yellowing lenses and cataracts as time goes on." ;)

So, yeah. With contacts, I usually need sunglasses. With vari-focal lens in my glasses, photography is a chore. Glasses make using the viewfinder complicated in either case. And either way, focus is an endeavor. I'm not sure I have a point or an answer, other than, "You're not the only one."

I'm always impressed by those who get super sharp focus and love seeing those photos. One of these days, I'd like a couple days instruction from someone who can do that, so that I know what I'm not doing right. But I do try.

I used to do pretty well with an Olympus or Yashica rangefinder on film. Rangefinder focusing has always been easier for me -- lining up the bright double images -- even though I've had a Pentax SLR of one sort or another for over 40 years. I tried a Katzeye split image screen on my K200D, but there was still the glasses thing with the viewfinder.

Just guessing, of course, but sometimes a lubricant can harden (migrated from the focus helix) or the blades can oxidize and get stuck also. Someone may have opened it up, taken the blades out, and then it was a mess to put them together or even separate them. As GUB mentioned, sometimes they "come apart" -- collapse -- as a result of a fall or other issue.

Use it wide open? Maybe there's some interesting bokeh in some situations? Assuming all the lens elements are ok, it should be usable. Just use shutter speed and ISO for light adjustments? Maybe neutral density filters?

Someone sent me a lens from a 'famous auction site' with a filter stuck on a bent rim. I carefully opened the rim, removed the filter, and there were no lens elements inside aside from the rear element. That was a great surprise. Since it was advertised "in perfect working condition," I sent it back. Cant' work without glass in it.

Is used equipment selling well?
Posted By yucatanPentax
Replies: 65

Now, all this is being said in good humor, not attempting to poke at anyone... There's an interesting other thread going about the quality of used goods purchased and I share the OPs pain and experiences to some degree.

And this is all just "for example" talking, not actual cases or prices... I don't really need a new body. My K-3ii and K-5iis are working wonderfully. But I was wondering about a K-S2, just for putting together a small, light travel kit and, well, just trying out a different body. It's been several years since I bought a body. The smaller size and the flip-out screen would be new to me.

So, assuming that "around a couple hundred bucks" would be a good price, I look around. There's some with a lot of other stuff -- lenses, flashes, a camera bag -- that I just don't even want to hassle with and wayyyy lots more money. And then there's one for "around a couple hundred bucks", but it turns out the seller's shipping method is expensive, plus there are fees, and possible duties. The price has now gone up wayyyy more than a couple hundred bucks for a used body that I don't really need. And I don't truly know the quality, even if the seller is reliable and so forth, I don't know how it's been treated, etc.

So, maybe others don't match this thought process, but mine went, "The new body announcements will be coming out. I don't need a body. Why not bank the $200-$300 toward that until we know more?"

Sure, it is likely to be $1200 and now I have $300 towards that, especially if K-new is very desirable. To me that means general improvements here and there, plus a K-3 quality body with tilt-swivel-pivot-ish screen. Maybe wifi, or whatever little surprise trick Pentax has come up with.

So, combined with new body anticipation, I've talked myself out of buying at the moment. If my K-3ii dies, I'll get by for a little bit with the lovely K-5iis. In reality, they'll likely still be perfect when the new body is on the shelf, and then I'll have to talk myself into spending those funds.

No one ever said humans were logical, Mr. Spock. :D

P.S. The only negative experience I've ever had with a Marketplace seller is someone who came here selling one item and then vanished after. ALL other experiences have been way ABOVE PAR with our Marketplace here. Still, a used item is a used item. "New" has its own allure. :)

I can only say that I share your pain. The number of obviously defective sales from all sorts of sources have been rising. It's not like it takes an expert to see the mount end is dented in or the midst of the lens is wonky and wobbly. Or the "snappy iris" is in fact a snappy moving lever, but with an unmoving aperture.

Some are obviously total fools, but a rising number seem to be intentionally dishonest. It's hard to imagine that people regularly involved in camera and lens sales are truly so sight-impaired.

(And yes, I did get a lens once that had something looking like dried out baby food smeared over the rubber focus ring. "Mint") :D :o :confused: :mad:

Same here. Unless someone says "offers accepted," etc, I usually don't want to waste my time or theirs. If I can't tell something about the condition from the photos, I usually don't want to waste my time or theirs. If there isn't a good written description of functionality, same. etc, etc. So, the ad quality matters.



Yes, that's how I've made almost all my purchases on the Marketplace. Unless "priced to sell" upfront, something will have a price drop -- bumping it to the top -- that catches my eye and I go through a "well, for that price, I could probably make some use of it, even if I am not desperately needing one of those..."

Unless the prices drop, it may not sell. If an item isn't selling, the price may be too high. End of.



These just baffle me. "I don't want to spend time sending various places" or similar commentary. It is very rare that someone needs an entire new package of items which corresponds exactly to the package being offered for sale.

Very frequently, there is something -- one item -- in a package that I would buy at a reasonable price, but the listing states, "Not breaking up the package at this time." OK. Good luck with that. Unless it is such a low price that the pricey package is irresistible, they usually sit for quite a while.


There's another little something that enters into the calculation. Paypal fees and shipping fees raise the cost to the buyer. Sometimes, that is as much as $50-$60 tacked onto the asking price. While I realize those amounts don't end up in the seller's pocket, they do come out of my pocket. So total price is important.

If a camera store offers something new or used with free shipping and no taxes and credit cards accepted, none of those costs are involved. Whether on eBay or the Marketplace or Shop Goodwill (scary, but fun if cheap), the added costs are always a consideration. Unless the total price is competitive, I pass it by.

But then again, I guess I'm at a stage where I don't desperately need something anyway. Most are "want to try out" type buys. And, yes, news about a (someday coming) K-3 replacement has paused my interest in other bodies for a moment.

My copy of the 12-24mm is sharp. Maybe not the sharpest tool in the shed, but it certainly isn't what I'd call "soft all over."

Let's see some pics tomorrow and maybe folks will have some ideas for you. (But, I agree, send it back if possible.) The price on these has been considerably lower lately for a good used copy. But I've never seen one for $160. I got an open-box copy about 10 years ago for $500-something. I thought it was a steal then.
