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)

The Samyang can definitely give pretty distorted images, though...







It's the centers that are different, I think; I'll have to get some comparisons one of these days, like I said.

I guess I'm using "lens flare" in the video game/JJ Abrams definition - yes, the ghosting. The flare around bright lights themselves isn't bad. But there's definitely more ghosting that I'd expect from a Pentax OEM lens.


Yes, but I'm one of those strange people who doesn't care so much about accurate landscapes; I want fishiness in my fisheye lens. I'm not a particular fan of UWA lenses and I feel like Samyang is trying to make the fisheye more UWA-friendly, which is not what I'm after. I'll be curious to see Pentax's upcoming FF fisheye zoom and how it compares to see if I'll be upgrading to it or not. I probably will sooner or later; I have been wanting a weathersealed fisheye for years!

In the meantime, I do still like the Samyang 12mm and time will tell if I find myself liking its projection more or less. If I get really fired up, I'll do some comparison shots between it and my other FF fisheye (Zenitar 16mm) one of these days.

This is probably as suitable as anywhere. :) So far, I mostly really like the Samyang 12mm... the starbursts are way better than on the usual 6-blade aperture fisheyes, but there's a lot of flare. You can see some of it in the picture with the fountain in the foreground. It could really benefit from some Pentax SMC or HD coating. :) The sharpness is very good, the purple fringing is quite low - far less than on the 10-17mm, and contrast seems fine - I haven't really paid attention specifically but haven't yet felt like it's been a problem at all. I feel like it could use a little more distortion but it's not bad and I haven't gotten motivated enough to try to create a lens profile to make it more fishy, like a traditional fisheye.

I saw that a used one recently sold on eBay for really cheap - someone got a great deal. :)

A few more with the K-1 and Samyang 12mm...

Despite the "stereographic" setup, there is still a good bit of distortion with the Samyang, which is a good thing in my eyes. This shot has an example of the many-pointed starbursts that you can get with it that you just can't get with the current Pentax fisheyes... hopefully their upcoming FF fisheye zoom will be able to.

I'd apologize for hijacking but this helps keep the ad at the top. :)

Yeah, I assume mine was a later lens, and has the lens cap you described:



Here's the hood:



I wouldn't feel too bad about missing the hood; it was a pain because it clipped into the filter threads, so you couldn't keep it attached to the lens when the cap was on, so it would just bounce around in the camera bag or at the least, be one more thing to carry around. Not quite "perfect" in my mind. :) I only sold mine to sweeten a deal on my K-3 that I sold - it was my only prime for years and still worked well, but there was an offer on the table, so it didn't make sense to keep it when the 31mm Limited was sitting next to it. ;)

Someone should definitely buy this lens, it looks to be in pretty amazing physical condition and they're great lenses and small and light.

Nice lens, I just sold mine (without advertising) that I had bought new 25-some years ago, with some reluctance! I don't remember getting a case with mine but mine did come with a petal lens hood specifically for that lens. My manual and lens cap are different, too. Apparently there were some changes in packaging over the years; mine was also a Mini-Wide II with "A" setting so the lens itself is most likely the same. Regardless, a very solid and sharp 28mm lens; I used it for most of the photos of lenses on my selling page. Good luck with the sale!

K-1 price hike

Hmm... there's a D700 with grip and 35-107mm lens and Tamron backpack on Craigslist near me right now for $795... if I was a Nikon shooter, that'd be a no-brainer. Big, lazy pixels, the 12mp can make almost any lens look good. :) There's also a D750 for $1,100, a Canon 6D for $1,300, and I often see various 5Ds in the mid-$1,000s or less. So a C/N shooter looking for full-frame can get into it for less than the price of a new high-end crop body.

My old K-3 retailed for $1,300 when released three years ago, I think I paid maybe $1k for someone's review-copy one a few months after release, and I just sold it for ~$400. The K-1 is 8 months old now and retailed (until recently) for $1,800, so I'm sure we'll see used prices dipping in the next year or two. This is not really comparable to C/N though, since there's one and only one option if you want a FF Pentax, but once the K-1ii (K-1 2? K-12? sounds like a school system!) or K-1s or whatever it's called comes along, that'll help drive K-1 prices down. Heck, look at what K-5s are going for now, and that's got IMHO the best APS image quality you can get or damn close - it's crazy how cheap you can get such a great camera for.

Tamron 28-75mm vs Pentax DFA 24-70mm

Good to hear that you got one and are happy with it, and the focus tweaking is always useful although a pain; I'll have to check out the videos to see if there's a better way than I have been doing. (I'm sure there is, I usually end up noticing it on vacation and starting guessing and trying to focus on something nearby and then zoom in on the photo, not a great system! I have the focus charts at home but am usually too lazy to bother.) As an alternative to the 24-70, I'll mention what I ended up doing...

I actually almost bought Miguel's Pentax 24-70 but then he liked it too much to sell it. :) At that point, I was emotionally invested in the Pentax lens but might have still gone for the Tamron if I saw one for cheap. Unfortunately, neither lens came up at what I considered a good deal, and I suddenly realized that I had about a week before I was leaving for a vacation and had to do something if I wanted something other than using the 16-50 and cropping off the vignetting.

What I ended up doing was going the prime route. I already had the 31mm Limited for a reasonable wide autofocus and the FA 50mm F1.4 for a slightly longer. I started looking at wider primes and settled on the Samyang 24mm F1.4; the fast aperture sounded very intriguing.

As it turns out, I ended up shooting more than twice as many photos with my manual focus lenses, and while I brought a decent pile of lenses with me, I only used the Samyang 12mm fisheye, 24mm F1.4, 85mm F1.4, the Pentax 31mm and 50mm, and the only zoom I used was my Tamron 70-200mm, and only at a zoo we visited. It did mean a fair amount of lens swapping, but it did give me faster apertures than I could get with the zoom - the 24mm in particular can make some interesting low-DoF photos that you just can't do with a zoom, so I'm pretty happy overall. Yes, there's a few out-of-focus shots, but the catch-in focus works pretty well and when it didn't, going Live View and using focus peaking worked great. The vast majority of the time was spent between the 12mm fisheye, 24mm, and 31mm. I never even touched my M42s - although I did take a very few number of shots with my LensBaby, come to think of it.

For the future, I will probably keep an eye out for the Pentax 24-70 - I won't "need" one for a while so hopefully some deals will come along; it would be nice to be able to sometimes head out with just the camera and not need a bag of primes. I am also watching eBay for an old Sigma autofocus 24mm F2.8 - I just sold my bought-new-20-years-ago Sigma manual focus 28mm F2.8 which I liked a lot, and apparently the 24mm is similarly good and small and sometimes sells for very cheap, so that'd be a nice small wide lens for when I want autofocus. I didn't even know that such a lens existed until I startered researching.

I think I'm agreeing with you - I've never felt a strong urge to get a circular fisheye lens and while the 10-17mm is close to that on the K-1, it's not compelling enough for me to keep it, even with the fairly low resale value of the lens.

What I'm seeing with the Samyangs is less of the extreme fish look, which is what appeals to me. Here's a few examples from the 10-17mm of the look I like, with the fisheye effect across the entire image. The same photos on the Samyang would look a bit different, although whether for better or for worse is purely opinion.
