Floating element defined...
Floating element lenses have a cam system that adjusts the distance between the lens element groups as the lens is focused, particularly at close distances. As well the design is said to help minimize certain forms of aberration.
The Nikon nomenclature is CRC (close range correction), at Canon it's a floating system, and Hasselblad & Mamiya call it FLE (floating lens element).
Note that some Mamiya lenses have a DOF only indicator in the same location as the K/L f/3.5 90mm L floating system adjustment... in that case it just indicates the DOF.
I have not noticed any change of focus after adjusting the floating system, but I do mostly landscape work... I just checked it on a close object and there doesn't seem to be any change of focus...

taking action...
One of my Photo Plans for the year is to "shoot medium format film (6x7)". So toward that end I got out and started to dust off my Mamiya RB67. I have had this kit for a couple of years... purchased used for a very reasonable price. The only lens I have i...
Dusting off anything is a big first step...
but, hey, man, you've been dusting off that thing for the longest time ;-) my friends bought themselves those Hasselblads 500? 501? i'm just laughing my head off because i know it's going to take awhile for them to use it. they're currently looking for 12...
hahaha, I knew I could count on you...
photos speak louder than words... and I was out and about in the late afternoon. 6x7 means ten images per roll... I used my ball head tripod, never again... the image is reversed on the ground glass and getting everything aligned was not so easy... a thre...
Oooh, sure why not...
about those 120s for my friends :-) All these toys… not enough moolah!!! Btw, that apartment complex/building looks like it has a lot of potential. Could make for a nice big graphic print.
This is quite big
I got a chance to play with it last Tue (what a coincident), lovely cam Do share with us your shots with it.... HANWE
Thank you Quan...
Here is a photo going/returning from the shoot this afternoon... I will definitely share the results... I had some expired film loaded, so we'll see how that turns out... as well, my first time to use scanning by the lab... Have to wait until late Februar...
Thanks Casey
is this taken handheld ? Since Jan 1, keep on taking photos and as for print will sort to the best family photo to print...hope wifey will be happy to see them (as she wish) The Pentax 645 also another "monster", all this heavy stuff I will have it a mis....
that picture of my bicycle...
was a point & shoot digital just to show how I carried the RB67 and tripod... sorry if I was unclear on that point... I will drop off my negatives at the Lab tomorrow, so the results from the Mamiya will take a few days. The New Year period is definit...
Heavy Artillery
Boy ! The big guns are out ! Works like bellows ? Do tell more pls. As Quan mentioned, was toying with the idea of a 501 plus a digital back. Looking forward to more !
Take a look at the Pentax 645Z...
I visited the Ricoh (Pentax) showroom just before the camera was available in stores... it's very nice. Handles like a dSLR and the menus are very familiar as well. There are some new lenses and I believe that some(?) legacy lenses can also be used. A use...
Yep, I checked this one out albeit briefly...
saw the pics from it too. Same guy who lent me the 21lux in Roxas :-) It's a fantastic camera for the price! Oh yeah, he also has the regular version. Hahaha! I asked him before why he doesn't read reviews before he buys. He says he'd rather just buy it t...
645D
was considering that some 3-4 yrs ago ? There is a fantastic report/article 645D vs D800E on Pentaz forum. That made up my mind on the D800E ... Which I regretted. Large file sizes are not my thing. And for the stuff that I do, quite overkill. Besdies, Th...
Hasselblad has always been a touchstone for quality...
I hear you about large file sizes... I know some scan their film to a smaller size and my film scans are larger than my 5DII files, but I just appreciate the flexibility of the larger scans since I do crop ;) For some reason I am still looking for a small...
And I thought the Hassy was big. Criminy!
Your bike must be hard to steer with that thing in the basket :-) Nice camera, Casey. This is the first I've heard of the floating system. It appears that the adjustment is part of the camera instead of the lens; does this adjustment work for all lenses t...
Jeff, the floating system is lens specific...
With the Mamiya RB67 and the K/L 90 f/3.5 L the floating mechanism is implemented on the lens... Please see the attached photo. I have labled the relevant parts... (A) for setting the f-stop in a range of f/3.5 to f/32 (B) for setting the shutter speed in...
Another question
I think I follow, but with your two step process, first you're focusing on the ground glass and then you're making an adjustment to the lens. If you re-check the ground glass will the image still be in focus? I'm sure this is easy once you try it but havi...

Very interesting.
Hi Casey, Thank you, this is very interesting. Whilst “the 15 minutes of fame” I receive these days is mostly for my candid photography with the M9, I have a soft spot for the “slow serenity” of medium format film photography. Shooting from chest or waist...
Thank you for taking your time to write...
I hear you about "15 minutes" vs. "slow serenity"... on social media for the most part I stopped indiscriminate use of the "L" button... if it's worth one button click, then it's worth a short comment. It might sound corny to say that I shoot digital for ...
To shoot film for yourself
is a nice way to explain it for me too. I look at the prints when developed but it's actually the process of shooting I like. I'm hopeless at scanning. Typically I get a contact sheet when I process my negs and file that with the negs and don't bother abo...
Another Hassy fan. Perfect. :-)
Hi Richard, I used my old Yashica TLR last weekend trying to take a few pics of my kids and had the same challenge you described; they would run to the right and I would pan to the left. :-) I hope you can share some pictures with us from your film camera...
A moving subject
Jeff, that is quite a feat. :) Those kind of shots are hard enough with digital. I just posted a shot from the Trip 35 in reply to Casey. Would you accept an X-Pan shot in the meantime? ...
An X-Pan! You have good taste in gear.
I've wanted to try one of those for years. So cool. Jeff
