I like these images, but very surprised that the Mamiya shift55/4 can be used on the Z. I am very interested in details: Is it a 645 C series lens or something else? Is the lens used with an adapter, or has it been converted to P645 mount? I might mention that I used a variety of different Mamiya 645 C series lenses on K-mount, but have been unable to find a way to use these with the Z/D/N cameras.

The lens has been converted to Hasselblad mount and I am using it with an adapter. There is stil one for sale on ebay for a lot less the I paid for it. Object number 273525276723

Thank you very much. I have a few questions about the lens, and have sent an inquiry to the seller. I appreciate your information.

The final post from my recent trip (apologies if it's getting too much!).

I always intended to do some of the Grand Canyon in Black & White. I found the medium suited different pictures compared to a colour rendition - the views that are all about texture and tones.

So here are the ones shot for B&W:

With 150mm FA lens

These B+W shots are great, Ed. These are A.A. worthy. The other shots are also excellent, of course....except that it's Vegas.


One of the best bumper stickers I ever saw was out in Nevada: " I (heart symbol) Las Vegas"---in large type, and below it, in much smaller type--"...in my rear view mirror."

Nevada itself is quite an amazing place, very under-rated.

I like that second one quite a bit. The lighting in landscapes like that can get really abstract and wacky and cool.

Sometimes I think the 645Z and Pentax 67 75mm f 2.8 AL may be a case of overkill for flower photography, but I like the results anyway. In addition to excellent rendering and good color fidelity, the P67 75mm f 2.8 also offers very close MFD, making it easy to fill the frame with larger flowers--no cropping on these except minor ones for framing purposes.

These are nicely done but how does the image compare to those done with the P645 macros? Is it the closer distance and different perspective you like? Most are using longer focal lengths at least partially to give more working room. Just curious. I have the P645 and my medium format experience is only with film.

The differences are perhaps a little subjective and difficult for me to describe. However, I will say that my macro lenses, including both the 645 90mm and 120mm as well as smaller format macros yield for me a more accurate, more clinically correct image. The P67 75mm/2.8 as well as the P67 55mm f 4.0, in addition to the slight distortion of a wide angle lens held close to the subject, provides a less accurate but more dreamy type of image. Perhaps someone with more optical knowledge can provide a better explanation.

No, I don't think a better explanation is needed. I was hoping your reasons were along this line. It is a subjective preference and helps explain why I never wanted to give up my SMC K lenses for M When shooting 35mm film. There are unique rendering qualities in the color, bokeh, and contrast with certain optics that can best be understood only while properly viewing the resulting artwork. Glorifying measurements from an optical bench sometimes leaves us with a cold, clinical, exact image lacking life.

I perfectly agree. In APS-C/full frame terms, it is maybe the difference between the FA31/43/77 limiteds and more modern lenses such as the DA35 and 50mm plastic fantastics, which I also like and use.

Nice images. Perhaps better depth of field over the flower than the 120 macro at lower f/no (although I don't know your settings). I don't think Emil Wolf covered "dreamy" so I'm thinking "dreamy" is more of an artist topic than optical expert topic.

Thanks for your comments on this elusive topic. My settings were probably with aperture wide open per my usual use of the P67 75mm f 2.8.

Magnificent shot, Mike. How many frames are in this pano?

thx Ed. its 3 frames. I didn't bring the 35mm with me and needed a wide fov.
