I sold mine after a while. It was greenish compared to the other P67 lenses. I still have the 55-100 and 75 2.8 AL.

oh yeah that strut material would take some load for sure. I tried to make a bridge like support with ratchet straps and a short perpendicular pipe but it had to be from the bottom to flatten the main pipe, so was in the way of the camera and head......

thx texan!

the camera is on a Wimberly Gimbal version one.

the two angle poles stiffened the cross bar significantly

the cross pole was quite springy , esp in desert winds. perfect for 500th of a second (or greater) with IS on. I did one video reference with the 1DX2 hang and the rolling shutter was like jello in an earthquake......

the poles were aluminum 1 1/4" with steel sleeve connectors. each pole is six feet long.

if more rigidity was the objective I would have used one 30 foot length of steel pipe and a ten ton truck to bring it and more assistants , instead of one.. mobility was key.

the desert wind that day was around 11 MPH and the cross brace was fine, but we wrapped the set up well before the afternoon winds of 21MPH......

...it was a great flight and the 28-45 performed quite well. This was the one time I can honestly say I wish I had that 25mm...... The 28-45mm is not as sharp side to side when shooting straight down as it is when looking forwards, I suspect the 25mm prime would perform better in that regard, due to less moving parts and overall weight....

heres a clue as to which photos were for assignment

Ed, the first says adventure or tourism , the second says suspense or military, to me . And yes , I'm sure that large prints have a different feel on both versions. On the iceberg I submitted above , the print looks like a the ice is alive and might take flight any moment, on computer less so , way less....

Great behind the scenes texanandrew. I wouldn't want to be driving that lift!!! (into the painting). On another note , I am prepping for a straight down shoot and am using AF fine tune adjustment to set true focus pointing straight down. With AF lenses, the elements float and the fine tune adjustment is different for normal straight ahead shooting, versus straight up, or straight down. For my current goals of being at 28mm on the wide zoom looking straight down I've got AF fine tune adjustment all the way to -10 and wish it went to -12 or -15....

Just something to look into for your 35mm as it will help to nail point of focus instead of relying on greater DOF.

Its also fun to mess with the white balance on these. Shoot tungsten balance in daylight, dial in the gold , those areas will be towards properly balanced and the other areas will be very blue. I'll look for examples , but they may be smaller format than this forum allows....

Flange to Focal Plane for 645z

I second the above idea, remove rubber ring at focus, and mess with the focus screws until you have the infinity where you like it , thats what those screws are for. Do have coffee and patience and time when you do this with a zoom lens, as you will want to check it at the wide end, middle, and tight end on a zoom lens.

Also , do your adaptors match, all same brand? All originals from Pentax? Some third party ones have been known to sag under loads like the p67 55-100mm. Sag could even create a small "tilt" effect , where the top of your image will be not quite at infinity focus but the bottom will......
