Absolutely! The hood is loose but I'd rarely shoot without it. You just have to be aware of it - it has to rotate a bit before it'd fall off. If I were keeping it, I'd probably try thickening up the detent, maybe with some light paint or clear nail polish. The replacement hoods are stupidly expensive so It's worth fiddling I think. My 50-135mm hood had similar issues as it aged; I assume it's a common annoyance.

As for pictures - yeah, I've got a zillion from it online, including on a K-3. :)

Everything on the first five pages is from the K-3, you can see the exif data by clicking the link below. Each pic is sized 1920x1080; you can click it then click the magnifying glass to zoom in. After the first five pages, you may find ones from the K-5, K-7. and K20D, along with more K-3 ones.

One more note regarding the hood - I should note that it's loose in how it clicks into place primarily. Other than that, it is OK.

Time to unload some more lenses... I've listed individual prices and weights; to calculate shipping, you can look at the weight , round up slightly for box/packing materials, and figure shipping from zip code 14586. PayPal is preferred.

Most prices lowered November 19th!

Pentax DA* 16-50mm F2.8, $350, 2 lb
First, the great Pentax 16-50. This one was actually a warranty replacement; I have the note from Pentax when it was replaced (2009) and it's worked well since then. The SDM focusing works just fine on both my K-x and K-1 (as well as the K-7, K-5, and K-3 that came before!) There is the slightest speck on the front lens element off to one side; it is so small that it looks like a piece of dust or dirt but I can't clean it off, so I assume it's there to stay. If it's a scratch, it's so shallow that my fingernail doesn't catch it, and it shouldn't affect image quality at all. The lens hood fits very loosely. Other than that, the lens is in fine shape. Included is the lens, hood, pouch, original box, and manual.



I tried to get a picture of the speck. You can see it on the right side in this picture:



Samyang 24mm F1.4, $370, 1 lb 11 oz
I have very mixed feelings about selling this but I'm just not using it enough to warrant keeping it. I originally bought it after getting the K-1 in order to get a wider lens, then I managed to find a great deal on the Pentax 24-70mm F2.8, so that's what I end up using most of the time. According to my tags in Lightroom, I've only ever taken 563 pictures with it. It was purchased last November from Adorama and is in virtually new condition, no issues at all. Everything's included - lens, hood, box, manual, pouch.



Here's a couple photos taken at F1.4:





Vivitar 28mm F2.0 lens, $60, 10 oz
Like the 24mm, this pretty much sits on the shelf because of the 24-70mm. It's a Kiron lens and pretty decent quality. Unfortunately, it is not an automatic aperture lens; you'll need to shoot in Manual and do stop-down metering. The lens is in fine shape, nothing really to note.





Here's a shot at F2.0 on the K-1 along with a 100% crop, no PP done.





Tamron 35-135mm F3.5-4.2 with P/K AdaptAll mount, $5, 1 lb 11 oz
This looks to be in good condition, I've never really spent much time with it - I got it in a bundle purchase. Looking closely, I just now noticed what must be some fungus growing around the edges near the front element, but only at the edges, so I don't think it'd affect image quality. I can take a close photo if anyone is curious. It includes original front and rear caps and a (non-original) lens pouch.





Tamron AdaptAll P/KA mount, $40, 2 oz
If you want auto-aperture on that or another AdaptAll lens, here's a P/KA AdaptAll mount. I did grind the contacts slightly to help it work more reliably - it's been a few years but I recall that was a recommended fix for these when they don't work consistently. Last I checked this (not that long ago), it did work OK.



Promaster Spectrum 7 MC 28mm F2.8, $5, 8 oz
Another lens that came with some other gear. Your basic cheap film-era 28mm. Seems OK but doesn't seem to have a great reputation. No auto-aperture. I have other similar lenses so don't need this one.



Vivitar Series 1 70-210mm F2.8-4, $15, 1 lb 15 oz
These are well-regarded film-era zooms, this is a Komine-built one (version 3) with no auto aperture. The real problem is that there's a little bit of fungus in the middle. I don't think it'd affect your pictures unless you're stopped down all the way, but I haven't tested that. Comes with the original manual.



Quantaray 70-210mm F4-5.6, $10, 15 oz
I bought this new many years ago and it was my only telezoom for many years. Supposedly it's actually a rebadged Sigma. It's OK, nothing remarkable one way or the other; I was certainly happy enough with it on my K1000 but I wasn't very demanding. It's a push-pull zoom that's still fairly tight and it does has auto-aperture so works nicely on DSLRs



Vivitar 80-200mm F4.5 Auto Zoom, $5, 1 lb 9 oz
Yet another that came in a group of other lenses. The good news is that this is a solid Kiron-built metal lens with a consistent aperture and very little dust inside. The bad news? It's a push-pull zoom that is pretty loose, it's not auto-aperture, and there's a scratch on the front element. I do have the manual for it!

You'll just have to go back. :) It was really fascinating. Unfortunately, my wife couldn't make it on that trip; I wish she could since she was lucky enough to go to Space Camp when she was young, so it would be a return for her.

Those rockets just call out for a fisheye, like the skyscrapers in NYC...



The Space Shuttle (actually a test replica) makes for an interesting fisheye subject, too. Test replica or not, I still get choked up when I see a shuttle in person.

Thanks! I'm glad you like it. I do like vertical fisheyes too, they can really bend reality even more than landscape ones. Like this - this is actually a complete in-line Saturn V rocket with a section removed so you can see more, but the picture makes it look like they point in totally different directions.



Vertical can also give an almost vertigo-like converging lines appearance, too!

The Samyang 12mm is not too big, I don't think. It is fairly wide, and it is remarkably easy to get one's fingertips in the corner of the picture! I seem to find that happening a lot more with the Samyang than my old 10-17mm.

The 10-17mm is remarkably small, though. I remember comparing it to someone's Sigma 15mm fisheye a number of years ago and being amazed at the difference in size. I will give up a little bit of size for better PF control and the extra aperture blades!

What's that, you want excuses to buy another fisheye? :)

My dream lens is a FF version of the 10-17mm, but weatersealed, with an odd number of aperture blades (for starbursts!), and of course, much better control of PF - the 10-17mm really suffers in that regard. The Samyang has those much, much more under control. They do have a FF fisheye on the roadmap, I hope it'll have those features - if so, the Samyang will quickly go up for sale! But for now...

Ahh, someone else with the Samyang 12mm... I usually feel like I'm the only one! :) I'm still not convinced that I wouldn't prefer a "traditional" fisheye - I like the distortion, thank you - but it is a very nice lens and it's great to be able to get good starbursts. Here's a few of it on my K-1:

Sorry, I just saw this and I wrote a longer reply in a PM - I don't want to hijack the sale thread - suffice to say, head over to the Nikkor Lens Club thread for more info.

Regarding the lens for sale - just for clarification for whoever buys it - with the adapted mount, does it meter like an M or an M42 lens? They're not the same (as you probably know.)

With an M, the camera can stop it down but doesn't know what aperture you're using, so has to stop down to meter. You have to go in Manual mode and press the Green button for the camera to manually stop it down.
With M42s, the camera is not capable of stopping it down and you are seeing the stopped-down image already, so the camera meters just fine without doing anything special in Av mode (and if you're in Program, it'll Hyperprogram to Av automatically.) You get a dimmer viewfinder but more flexibility.

I prefer the M42 way myself - I'd rather manually turn the aperture brighter for focusing then close it to where I want it than deal with manual mode and green button, and that's how my Nikkor 105mm with stock mount behaves.

I use a Nikkor 105mm F2.5 on my Pentax bodies sometimes; it usually fits upside-down reasonably tightly with the stock Nikon mount. (Same with a few other older Nikkors.) I really like the lens, I'm a little ashamed to say that I use it a lot more than my Takumar 105mm. :)

It's worth pointing out that yours has the "A" auto-aperture setting, not all did. At one point, I had both. Obviously the "A" helps the value. I sold my "A" version quite a while ago, I kind of wish I still had it now that I have the K-1, it was a nice lens and a lot lighter/smaller than a 70-200 F2.8. I am currently trying to unload my non-A version; it's such a pain not having that setting. :) GLWS.

Dead thread... but I love my Auto Takumar 35mm F3.5! There's just something about the look of it that I like.

On a K20D...




The five blades can also make a nice starburst. On a K-5.



And almost-a-self-portrait, on a K-3...



I haven't done much with it yet on the K-1 but I do plan on it!

It's something, all right. I'm not sure how I feel about that picture but it is something you couldn't do with a regular lens. :)






QuoteQuote:

I get that there are ways to decrease some kinds of distortion with fisheye lenses, though that may often be by increasing the distortion of something else by choice of framing, But if someone complains about distortion when using a fisheye lens, isn't that like a diner saying that this or that type of fish tastes too "fishy." (Does anyone say a steak tastes too beefy?)

I get of course that their might be too much fisheye distortion for the way one wants to capture a subject. I get that different full-frame fisheye lenses might offer choices of how much and what kind of distortion to use, and making those lens choices are about creative decisions serving a picture.

But isn't the typical fisheye lens, by definition, a tool of distortion, imposing on the world, or drawing out from the world around us a kind of plasticity, a kind of previously unseen potential for change and movement? And don't people who want to flaunt their fisheye photos love that about the fisheye lens type?

Or is there something I am completely missing when people talk about de-fishing images or reducing the distortion like it's something to avoid?



Some people just don't like the fishy look (no account for taste, I know! :) ) but a defished fisheye shot can often be as wide or wider than a rectilinear UWA lens... and yet I want more fishiness! I love the distorted look, different than we'd see with our own eyes, and I love how the slightest change in perspective can make for a very different photo with a fisheye.

I also like that you can do really different things to create different "looks", like this shot where there's a bunch cropped off the bottom, putting what's normally in the center at the bottom of the image: (10-17mm on my old K-7)
