One further note: The in-camera processing only works with Pentax lenses, and even there, only with DA, DA*, DA L and D FA lenses, plus a handful of FA Limited lenses.

If you use third-party or older Pentax glass, you'll not get any benefit with the in-camera processing, but you will benefit from Adobe's processing if you have a good profile.

Adobe lens profiles for Camera Raw, Photoshop CS5, Lightroom 3

There aren't any Tokina lens profiles offered by Adobe themselves, for any lens mount, including Pentax's K-mount.

To date, I've not received any Tokina lens profiles from forum members, although this thread has somewhat cooled down, now that Adobe offer their own Lens Profile Downloader, albeit only as a prerelease preview. A quick check of their downloader doesn't find any Tokina profiles either, though.

Unfortunately, I can't guarantee that there aren't any Tokina profiles available somewhere, because I'm no longer actively checking for new profiles on this forum, or elsewhere on the web. I'm still happy to add any new profiles anyone has to offer, and definitely want to know whenever any are released, but I don't have time to actively hunt them down given that the official downloader is available now.

Which is all to say, there aren't any Tokina profiles that I'm aware of, but they may exist somewhere. If you find any, let me know. If you don't find any, but decide to make your own, let me know. And either way, best of luck to you! ;-)

AFAICR, the Kodak cooperation was only for the 645D, which indeed finally reached market with a Kodak KAF-40000 CCD sensor.

The MZ-D prototype was based around the Philips chip mentioned previously, and I never heard mention of Kodak in relation to it. (In fact, when Kodak released their own full-frame DSLRs a couple of years later, *they* weren't based around Kodak chips either, but rather ones supplied by FillFactory.)

If I'm wrong in that recollection, I'd love to hear about it, though.

That's logical. You've got a 1/2.3" image sensor, and a sensor shift stabilization system. The image circle hence has to be bigger than 1/2.3".

The question is, can you use a sensor larger than 1/2.3" without either removing the sensor shift assembly altogether, or reducing the corrective abilities of the system.




Yes, it was the same six megapixel Philips FTF3020C CCD sensor as the Contax.

Yup. And I believe in Japan, they went by the name "Victor", not JVC. Or at least, when I was a kid growing up in 1980s Hong Kong, you could buy parallel-import JVC gear in stores with a Victor brand-name, but otherwise identical to the more expensive JVC product. Well, technically it was just my assumption that the source was Japan, could be they used that somewhere elsewhere in Asia too / instead...

What Sten said. With raw, I can decide what gets done to the picture after the fact, and fine-tune the process.

Remember, though, if you prefer in-camera corrections, you can process raws in-camera on recent Pentax models, and apply lens corrections in-camera when you process the raws there.

Use one or the other, not both. That will, as you guessed, over-correct.

(That said, if the profiles themselves had originally been made for use on JPEGS shot with the corrections enabled, they might be able to achieve a higher correction quality -- but it seems likely to me that the difference would be negligible and not worth the effort of making the profiles.)

So yeah, it's a one-or-the-other situation.

Battery grip for K-X?

The rubber flap is nothing to do with third-party grips, it is for the official AC adapter kit, which uses a dummy battery pack. You could of course use that flap as an access, but unprotected wires trailing into an open hole to the inside of the camera body is hardly a useful solution for a retail product.

lol no, not really. And in Japan, it's technically 株式会社タカラトミー -- there is no "exact" spelling, because there is no set-in-stone transliteration scheme to convert from a character-based language to one using the Roman alphabet.

Hence, the most official source is the company itself, and it is spelt with a Y according to their own official, Japanese URL, as well as their official company logo:

http://www.takaratomy.co.jp/

So no, it isn't spelled with an i. And Wikipedia isn't the be-all end-all of knowledge -- they get it wrong too...

I'm not Chinese, and don't speak it to any significant degree, but I can fumble my way through identifying characters enough to figure out it's not going to tell you anything.

The characters are, I believe, 新品待發佈.

Google says that translates as "new to be released". I'd say that's a reasonably fair translation. Very roughly translated through another site I use, I believe the characters literally translate *something* like "new product await become announce"

Count me in. K-5 feature set with more sophisticated AF and an even smaller (but still just as rugged / sealed / coldproof) body sounds ideal. So long as they can keep the ergo up to K-5 standards, anyway... K-r body is perhaps starting to get a bit small to fit the K-5's controls onto.

...and when bidding, bear in mind they only cost 200 yen in Japan -- that's US$2.43 at current exchange rates. I've seen some of these going on Ebay for insane prices, despite the fact there's a continual flood of them being added.

By the way, tiny thing, but it's "Tomy" with a y, not an i. ;-)

Any News on that rumored 25-350 DA* lens?
Posted By knoxploration
Replies: 35

He's right. The greater the zoom ratio, the greater the compromise that must be made optically to create the lens. a 14x zoom is by necessity going to involve a much greater compromise than a ~4x zoom.



Suggesting that arbitrary focal length ranges are consumer grade solely because they're common among consumer grade lenses makes even less sense. A 3x-4x zoom has much less compromise optically, but it can still be consumer grade because either the sophistication of the optical design, the build quality / ruggedness, or both aren't up to pro-grade standards. The latter has nothing to do with zoom range and can be true even of a prime; the former can also apply to any focal range, but is decidedly more likely to be true of a longer-ranging zoom than a shorter-ranging one.

The patent didn't specify that. The part of the page which is Japanese-language only states that it is merely a guess from the blog author that it's a DA * lens, and I have to agree with Adam here, I don't see that being the case. This is a 14x zoom; I'm not aware of any Star zooms with more than a ~4-5x range. There's little chance of making a lens with this kind of range offering the quality of a Star lens, before you even consider the implications for weather sealing, etc.

You can see the full text of the equivalent US patent application here:

HIGH ZOOM-RATIO ZOOM LENS SYSTEM - Google Patent Search

This, if produced, would almost certainly be intended as a consumer zoom.

Having trouble putting on a Pentax Hand Strap.

Good point, I didn't realize the strap could come out completely, it was tight enough I thought it was stitched in. I'll give that a try, and test it with my battery grip too. Hopefully this'll sort it out for me -- thanks for the help! :)

Edit: Tested the strap running the other direction, and it's significantly more comfortable. Tried adding the grip, and the shape means that the strap base has to be turned somewhat and moved all the way back, or the lip gets in the way. That makes the strap actually slightly less comfortable than without the grip, albeit still usable. No biggie though, I'd be likely to prefer the camera lighter when relying on a wrist strap anyway.

Thanks again to Canada Rockies for the help!

Just curious -- is anybody using the Pentax-branded wrist strap with the K-7 or K-5? I picked one of these up myself, and I can't for the life of me make it comfortable. There are very few photos of it online, and Canada Rockies' pics in this thread are about the best I've seen. (Thanks!)

My issue is that with the strap on, it's uncomfortable to reach the shutter button and both e-dials, and basically impossible to reach any of the other controls on the rear of the camera with my right hand, because my wrist is forced to come in from a 45 degree angle behind and beneath the camera body, rather than vertically.

While trying to figure this out, I realized that the design of Pentax's strap is very close to identical to Nikon's Hand Strap AH-4, but with one key difference to my Pentax version. On my one, the strap goes through the tripod base so that it enters from the bottom of the base, and the velcro tab end comes out the end of the base. Everything I can find suggests the Nikon version is the opposite way around, entering from the side, and with the velcro tab end coming out the bottom. (per the links below)

I'm wondering if perhaps my Pentax version could've been assembled back to front, but it doesn't seem possible to reverse it to try the other way around, as the rubber grip on the velcro strap end won't fit back through the hole in the base. Canada Rockies' post suggests that his version is the same way around, too.

Hence I'm unsure if this is a red herring, and it's simply not usable with the K-7 or K-5, perhaps if you have larger hands... (I'm 6'1" tall).

PENTAX Waterproof Remote Control O-RC1 vs. Remote Control F
Posted By knoxploration
Replies: 8
Views: 18,541
Just stumbled on this old thread, and figured I might as well correct the info here. The Remote Control WP *does* have a capability not available in the Remote Control F, but only if you're shooting with the latest generation Pentax DSLRs. (Or at least, the K-5 -- I've not checked the manual for the K-r, but I can confirm the K-7 doesn't allow the new feature).

Unlike the Remote Control F, the Remote Control WP has three buttons, and *two* of these work with the Pentax K-5. As well as using the shutter button, you can also press the zoom button to perform an AF operation without tripping the shutter. Handy feature to have.

Personally, I own both remotes, and think each is well suited to different purposes -- the 'F' is ideal when I want the smallest possible remote, as it slips in my wallet and I can't even notice it's in there. The 'WP' is a little over double the size, but it's ideal when I might be shooting in the rain, or want to be able to separate autofocus and shutter operation. I've not tried this myself, but I've also read subjective comments from other owners that it has a little better range.

As I said, though, note that the K-7 doesn't allow use of the zoom button to focus, and I'm fairly sure the K-x won't either. Somebody might want to check the manual for the K-r; being fdrom the same model year as the K-5, it may well support the feature too.
