A continuation from my August road trip through Alberta, Canada.

ALPA STC
IQ3 100 Achromatic
70mm Alpagon / IR filter
Two image stitch.

Actual stitch was wider, but after a few weeks of looking at the print on a 24x40 roll cut sheet, I'm favouring a less wide version that will be more suitable for 17x22 sheet size.

as jeff asked for some gear porn, here it is.
Contax 645 with 35mm distagon and the achromatic+
I use a RRS L bracket which actually is for the mamiya 645, it fits the C645 just nicly as well, though it blocks the lower ports.
There is also an RRS L bracket for the C645 but only in conjunction with the battery grip, which i dont have anymore. it got destroyed when my tripod fell("kicked") over. horrible moment.

Since i use this camera only on the tripod i also dont use the strap.

Of course the achromatic+ is the crown jewel of this setup, for the contax mount it must be one of the rarest phase one backs

infrared image of the basel-land area. you can spot the roche towers in the far.
we had some snow the past few days and since we had beautiful weather today i went to the chateau du landscron.
I regreted it though, as i had my appendix removed on tuesday and went up really really slow. but it did hurt nonetheless after the trip.

Contax 645 + 35mm distagon and achromatic+ with Haida 720 IR filter

Cool! I have never heard of that back, and didn't find anything on line about it.

It's interesting what you can learn on a "Fun with..." thread!
true, info is extremely scarce, i was actually thinking about making a youtube video about it. but i am simply not that guy.

but was important to know, its essentially a P45+ without the bayer filter, and or without IR UV filter.

if true, the back was only made by an order from bear images, who asked P1 to make a p45+ without bayer filter, the rest is history

it's a bit of a unicorn in the digital medium back world, even within the Achromatic back world. drevil's contax-mount version is even more of a unicorn.

they're pretty scarce, even more so than the IQ260/3100/4150 Achro's.

great to see a member out there making use of one and sharing images (and some gear porn) :)
