Maybe a pair of Cactus V6ii or 1x V6ii + 1x Cactus RF60/RF60X flash would do the job?

K-1 or 645D? I did it (not the sensible choice)

spectacular photo @lightvox!
I'm very happy with the 55mm on the 645D. It renders beatifully and I always loved having a focal length equivalent between 40 and 50mm (35mm equivalent) using the old 2.8/40mm pancake on my LX or the 31mm limited when I had the K-3. If I had decided in favor of the K-1 I would have bought the 43mm limited...

645z FAQ ('What about Metering, P-TTL auto flash and Lens correction function?')

Or do I understand something wrong? It's not that I can't live without P-TTL (A mode is not bad either), but It would be nice to have.

AF-540FGZ flash manual http://www.ricoh-imaging.co.jp/english/support/man-pdf/acc_st_af540fgz.pdf just states, that 'if the aperture of the lens is in a position other than A, the flash mode will switch to TTL', regardless of camera body...

According to the 645D manual, Ricoh homepage and pentaxforums' review of the 645D, P-TTL should work with 6x7 lenses via adapter using genuine Pentax flashes (different to K-mount DSLRs due to aperture coupling - even with 6x7 lenses).

However, I can't get it to work. The flash (Pentax AF-540FGZ or Metz 58-AF2) always fires with full power when I use my 6x7 lenses. Firmware of my 645D is recent one (1.33). Besides the 6x7 lenses I only have the D FA 55 which doesn't have an aperture ring, so I can't test how P-TTL behaves with a 645 lens in another aperture setting than "A". Without flash, im very happy using my 6x7 lenses on the 645D...

Do you have any information what I can do to have working P-TTL with 6x7 lenses or could someone please test how his or her 645D/Z behaves in the described situation? Thank You for help! :)

I don't have a K-30, but according to the manual http://www.ricoh-imaging.co.jp/english/support/man-pdf/k-30.pdf just press the 'info' button and then you can turn off shadow correction and highlight correction. I assume, their current setting is AUTO.

K-1 or 645D? I did it (not the sensible choice)

Last week I sold my K-3 because I realized I have so much fun with my K2DMD, LX and 67ii, that the K-3 stayed at home too often.
So I decided to ditch APS-C and look for something new. I've kept all my lenses which are 35mm compatible, including my excellent 31mm limited MIJ.

I've had a look at the K-1 since its long awaited release and it is such a fantastic camera. But today I pulled the trigger and bought an almost new 645D + DFA 55mm for a reasonable price.
Comparing data sheets, reviews, this forum etc. that wasn't the "right" decision. The K-1 is smaller, newer, faster and has a "better" sensor in almost every aspect. The 645D is a heavy beast with some quirks, slow AF, slow buffer etc. So why would any sane person decide against the K-1 in favour of the old 645D? :D
The 645D has a big CCD-sensor and produces lovely skin tones at base ISO comparable to my late K10D I was so happy with. I've tried to achieve that look all the time with my K-3 and serious Nikon bodies that I borrowed for events (absoluetly great and reliable workhorses!), but that was always a tough (and time consuming) job for me. I'm sure that there are many skilled lightroom artists that can achieve a comparable look with calibration, local adjustments and other tricks, but I'm just spoiled by Portra film and my old K10D...

Another point is that I'll be able to use my 6x7 lenses without the limitation of green-button metering, because the aperture is coupled with the body even with the 645-67 adapter.
Green-button metering with K-lenses has never been reliable enough for my taste due to the mate-screen dependency (fast apertures always overexposed, slow apertures vice versa) and using live view is too cumbersome for me when shooting outdoor portraits. I really like using the aperture ring on the lens because I learned photography this way when I was a kid (with an old K2DMD I still love :D). Maybe some day I'll find the venerable AB-82 split screen for the 645D and than I'll have a similar analog feeling again. The 645D is not for every day use, but hey, that's what smartphones are for! (don't kill me!)
Right now I'm just happy I decided this way and wanted to share this feeling :)

I agree that it looks terrible and the prism is probably a badly abused Pentacon six prism (compare here: http://www.butkus.org/chinon/pentacon/pentacon_sixtl/body08.jpg )
The body itself seems to be actually one of the earliest models, if you look at the winding lever and other details described here The earliest Pentax 6X7 – Pentax67.net and Pentax 220 prototype and preproduction Pentax 6X7 cameras – Pentax67.net but I also suspect a bad spray job instead of anything special...

Just found this on eBay:
Pentax 220 Prototyp der 6x7 67 67II, Prototype Profikamera, Silver Asahi | eBay

Without doubt it is a very old example with all the pre-MLU signs. But don't you think this is some homemade job because of the serial no on top and the handwritten lettering?
According to this site: Pentax 220 prototype and preproduction Pentax 6X7 cameras – Pentax67.net there were no working samples of the 220 which was supposed to have mirror lock up (but the production model had not prior to 1976)

Pentax 67 - Which lens allows for super tight portraits (shoulder-up, neck-up, etc.)?
Posted By iDon

Views: 8,455
keep in mind, that the 165 LS has 5 aperture blades only. After having tried it for outdoor portraits (=nervous backgrounds such as branches or trees and aperture stepped down to let's say 5.6) I wouldn't describe the bokeh as outstanding. I own that lens and I do like it, but it actually is a special application lens. As written before, there are lenses with better magnification for tight head shots.


Did you expect, that a tele lens would make look a face look thinner? On the contrary. A tele lens slightly compresses facial features, so a face looks more plain, than it actually is. It's just physics;) http://stepheneastwood.com/tutorials/lensdistortion/IMAGES/tile1.jpg

fyi there is also a close up filter for the 105/2.4, but very hard to find. It's called "smc close up lens S82". Accessory: SMC Close-up Lenses | Pentax67.net
I don't have any experience with it, but I guess, it's more practical to use than an extension tube.

I'm not sure, if the normal primes (90, 105) or short "portrait" tele lenses (150, 165, 165 LS) are the best choice for your needs. As you noted, their magnification/min. focus distance probably is not what you look for.

I'd recommend you the 67 200mm (later version, not the Takumar one), because it's much more suitable for tight portraits and is a wonderful lens.
If you prefer a shorter focal length, another - maybe not so obvious - choice could be the 4/135mm Macro. It's capable of even higher magnification and you can get closer to your subject, if you have to shoot in tighter rooms or if you like shooting from slightly above. DOP and look should be comparable to your familiar 2.8/110.

PS: I also tried using the 165 LS with the shortest extension tube, but it's not very handy and I felt a bit restricted.

Portrait Lenses again..
Posted By iDon

The DA* 55 is a wonderful portrait lens with an ideal focal length for head and shoulder portraits. I use it as a successor for my FA 1.7/50 which strongly resembles your DA 1.8/50. You can also do great portraits with the latter, but I prefer the equivalent of a 83mm lens (in 35mm-film terms) over a 75mm and I think the DA* 55 has a bit more pixie dust.
Maybe the FA50/DA50 was designed more as a general purpose lens and the DA*55 as a special portrait lens with it's predecessor in mind, the FA*85.

If you read too much about portrait lenses in online forums you'll start to believe, that a longer focal length would always be a better choice, because of perspective and subject/background isolation. I tend to disagree with that. I'd recommend a 50mm-equivalent lens like the FA*31, Sigma 35 Art or your DA35lim. for portraits, when you'd like to show a bit more than just head and shoulders and also the emotional quality of the surrounding (if those are the right words for what I mean). This can give you a very natural and harmonious look and feel.

An 85mm equivalent lens like the FA50/DA50 or DA*55 is perfect for more focused shots with a flattering perspective.

For me personally anything longer than that is already too much. Unfortunately this also includes the FA 77, although you just have to love it when you hold it in your hands. In my personal taste, I'd be too far away from my model to keep contact and give instructions. It may work, if you have enough space and more experienced models.

Overall I'd say you're already well equipped with that great selection of lenses you've got. Just go out and look for handsome models :D

Why is metering with manual lenses unreliable?

if you use smaller apertures (let's say starting at 5.6) and don't correct your exposure after pressing the green button, the results will be too bright, even for RAW processing :(

So I've come to the conclusion that I'm going to use my manual lenses, but with live view only... focus peaking is also a big help.

I've read about this issue some time ago in another forum (can't find it anymore), but I haven't found a proper explanation.

In my understanding stop-down-metering (=using the green button) should be a simple and reliable solution. It stops the lens down to the set aperture and measures the light coming through.
Isn't that completely indipendent of lens transmission, diaphragm actuator control curve, algorithms etc.?
Shouldn't this method be more accurate than an aperture simulator found "decrippled" film bodys and todays Nikon cameras?

@seventhdr: this is an explanation why you can't just modify a K lens to an A-lens, but I'm afraid it doesn't explain this issue, because the camera doesn't need to know which aperture is set at the lens. It just needs to know how much light hits the sensor.

You can try to use a fairly new FA lens and test it with aperture ring set to A at every aperture value versus setting the aperture value using the aperture ring + green button. I'm sure the results will differ significantly and will show the overexposure issue.

edit:
@Ole:
thank you very much! That should be the reason...

Hey,
my K-3 and also my old K10d show an odd behaviour when I use them with K or M lenses.
Mode dial is set to M, use of aperture ring is allowed und green button is used to set shutter speed.
Both cameras tend to overexpose with smaller apertures. The more I step down, the brighter are the results.
Oddly enough metering works perfectly fine, when I do the same procedure in live view. I can reproduce this behaviour with all my manual lenses and also A/F/FA lenses set to another position than A. All those lenses work completely fine with my film bodys.
Do you have an explanation or even a solution for this issue? I'd really like to use my K lenses more often... :(

delay shutter release options for 67 and 645

what you need is a small mechanical device known as Autoknips (e.g.). You screw it into the shutter button (or connect it to the end of a cable release with older models), set the delay, wind it up and it triggers the camera like a cable release with a small bolt pressing down the shutter button.

Try to use the "Embedded" profile in the camera calibration section in Lightroom and not "Adobe Standard". It makes a significant difference when it comes to skin tones.

Pentax 67 question!

I'd like to add, that although the 6x7 and 67 have manual control only, they are not manual like an MX, which does not rely on batteries except for metering. All 6x7 Pentax cameras won't work without batteries and have an electronically controlled shutter.

I tend to disagree that the 67 is a significantly better camera than the 6x7 MLU. Except you define a black shutter release as better:D It may have minimal improvents, but the only real benefit is, that you now its not older than 25 years instead of beeing 25-45 years old ;)
