Leaf shutter (LS) lenses . . .

When cold weather writes stop to my flower photography, I confront the problem of what to do with an extensive Pentax camera and lens collection other than cleaning, checking hoods and caps, and shooting various test shot at miscellaneous objects around the house. This season, however, I have begun checking out my lens shutter lens collection, which is comprised of three Pentax lenses: Pentax 645 75mm f 2.8 LS, Pentax 645 135mm f 4.0 LS (2 copies), and Pentax 67 165mm f 4.0 LS. There exists also one Pentax LS lens that I do not own, the Pentax 67 90mm f 2.8 LS. In addition, I also have one non-Pentax LS lens, the Mamiya-Sekor 645 C 70mm f 2.8 LS, which is adaptable for use on K-mount but not P645 owing to incompatible registry distances of P645 and M645 cameras.

Apparently the major professional use of LS lenses is for portraiture, specifically to achieve subject isolation by creating dark backgrounds in bright ambient light situations. As an amateur not engaged in portraiture, however, I have found these lenses interesting for use with still life photography in any kind of ambient light situation. As examples I am attaching several test photos taken with the 645Z and Pentax 75mm f 2.8 LS.

Currently LS lenses do not seem to attract a great deal of attention here on the Forum, but I am interested to learn whether there is enough interest to create a Len Club devoted to them.

I love these, especially the fence.

The image with the heron backlit is very striking.

Couple shots with 645Z and Pentax 645 135mm f 4.0 LS.

Here are two shots from a medium format Pentax lens that is not much heard from nowadays, but which seems to offer lots of sharpness with nice rendering. At a 135mm focal distance, it is also a nice portrait lens even when not used in its LS mode to darken backgrounds.

Very nice images!

The 90/2.8 LS was my first 6x7 lens when I started with the system, mostly because it was relatively cheap. But recently since I’ve been doing some home studio experimenting, I’ve just recently started exploiting its leaf shutter capability. Your images give me inspiration for more subject material! I have the 165/4 LS on the way, it has a stellar reputation and am really looking forward to using it.

I’m definitely up for a LS lens club!

Your Rubbermaid model is tempting me to do some compatible fruit still-lifes (still-lives?) using used fruit. Unfortunately, I have to rake leaves today.

Thanks. When all else fails, you could take some photos of leaf piles. :>)

Will you will be using the LS lenses on Pentax 645 cameras? I have been using both P645 and P67 LS lenses on both the K-1 and 645D and 645Z but not on any film cameras. Let me know if you run into any problems, and possibly I can help.

Thanks for posting images taken with the 645 135mm LS ! Were these shot wide open? How do you like it compared to the FA 120mm?
