Pentax 67 SMC 75mm F/2.8 - Are you shooting one of this?

[aires35III]

Impressive ! You like analog cameras more than me. It is a performance.
Thank you for the advice. Actually my only issue to acquire a 67ii is the price. They are quite expensive on ebay, mostly in Japan with high custom fees (to France) and I don’t know where to find others.
Actually, I already have a Voigtländer Bessa iii which suits nice to my needs : the interior portraits. Its absence of vibration is a real plus. Its lens is nice too even if there is not much detail in shadows. Typically Voigtländer ? Other point is the bokeh : I discovered with it that such format and associated lens creates a bit too much out of focus to my taste. I prefer in this respects the 65mm of the Bronica RF. Of course, indoors enhances this effect. That is the reason of my choice of the 645, with a 55 lens. The 75 will be for the outdoors.
So, it would be fine to use a 67 Pentax for outdoors indeed. The results are really attractive and the outdoors increased distance and amount of light may be fine. Now I just need to find one.

David is a real creative artist. I wonder how many time he spent to design it. I presume that it is not his only creation ? I confess I did not get the principle very well but it seems nice, being such copied.

Thank you Asa32. The lens fits nice to the 645 apparently, with a very even coverage.

Thanks... The Mystic Twister is an optical illusion when rotating. If you give it a twist with your hand, it will rotate along its vertical axis, and while doing so it winds up the string, lifting it all slightly against gravity. This slows it gradually until it stops, and gravity then causes it to twist in the opposite rotation, this repeating over and over until friction effects decay the movement.

You mention the Bronica RF, and I'll just say it's a strong favorite, as I have two of them and the three lenses. It's very compact and handy. I wish the viewfinder had framelines for the 45mm lens, but the whole window does serve ok. Somehow it reminds me of another favorite, the Minolta CLE.

Back to the Pentaxes... some complain about the vibration of the 6x7 when the shutter is triggered, as it's described as "the clap of doom". But the vibration is largely imaginary. I saw a short video clip in which a 6x7 owner placed his camera on a tripod, then balanced a coin on-edge on the top plate, and fired the shutter with a cable release. The coin did not fall. It's said that any vibration effect is maximized around 1/30 sec shutter speed.

When the P645N was still fairly recent on the market, a Canadian photo website tested one shooting a distant cityscape with a long lens. The shutter and mirror were designed to minimize vibration. As I recall the results, he shot the scene both on tripod and hand-held and could not see a difference.

I understood the magic twister !
Thank you Doug for these technical knowledge for the 67 and the 645. It is important to me to know the 67 vibrations limits. And yes, it really appealing me. Don’t you encountered a transportation film issue ?

I like the 645 a lot too. Especially because of the 65mm, in B&W cause I prefer colors from Zeiss or Leica. Full of details in shadows, contrasted, and with a slightly harsh bokeh which I like very much. The field angle associated with the 6x4.5 format is to me a perfect companion to take "ordinary live" scenes. But the camera seems delicate : I already have some issues, one with the crank lever. One internal part of the freewheel made of aluminium alloy broke. Not a big deal but it shows that it is not a Leica quality. It was not the same price. There is a bit lag when shooting, too.
I saw your pictures with the 45mm : isn’t the 1m too far as a minimum focusing ?
Regards to the sensivity index : I guess I’ll try to lower mines too. Especially on the Bessa iii where the shadows are a bit blocked. Isn’t it an issue for highligts ?

I come back to the main subject : does anybody compare the 75AL to the latest version of the 90mm 2.8, in terms of contrast and resolution ?

 

[Doug]

^^ do you mean the 75mm and 90mm lenses for P645, or P67? ^^

I have not had film transport problems in any of these cameras, though it's rumored that the Bronica RF645 winder may have. Mine have been fine but I'm a gentle user. 🙂

The close focus limit on the Bronica 45mm has not been an issue for me. With an RF camera, the closer the subject the more of a problem viewfinder parallax becomes.

Film is quite tolerant of a little overexposure, highlight detail survives it well, unlike digital where it can blow out with no detail. And with digital it's often useful to underexpose a bit to protect the highlights, as one can dig detail out of the shadows in post... pretty much the opposite of film usage.

it's too bad there isn't a database of digitized photography serials on the internet. they used to do real lens tests back in the day, and you would have been able to get a reliable answer more easily.

in any case, does it really matter?

 

[aires35III]

I am asking for the 67 lens. For the 645, I already made my choice : the 645 55 2.8 AL. By the way I am surprised that nobody seem know it in this website since it is apparently be one of the best lens available.
It sounds good that your 67 have no winding issues. Internet blogs may exaggerate.

Yes Aizan, that would be a good thing. To me the best comparative mean is flickr to have an overall result. Unfortunately films are few used nowdays, the best media to see the qualities of a lens in my opinion. I did not take your point : do you mean if it matter for the 75AL and the 90 comparison results ?

I began a new roll for my Bessa iii, with a Portra 160  overexposed to 100, let’s see. The next challenge will to find a laboratory during the sanitary crisis. And to find a good one : the processing work is now mainly rubbish…
