Pico with Schneider 180T

When I was putting the above setup together I wasn't sure which length to order so I ended up getting this set on eBay:

I've since used these and RAF extension tubes and am happy with both.

If you choose to try the Hasselblad V adapter route, another benefit is that the opening is larger than 65mm which will allow you to use more of the 180T's image circle. You will also be able to use a shorter tube because the V adapters add length.

RAF is awesome. I've used S.K. Grimes and RAF for custom step-up filters. Both do excellent work. RAF costs about 20% of S.K. Grimes... so there's that :)

It looks as though RAF has all of the parts that I need. 65x1 60mm extender, 65x1 Hasselblad V female thread and 65x1 copal 0 bore male thread. All the parts are here in the US including the AS Pico V lens board.

The most lateral shifting I would ever need is around 10mm. Vertical is where I could need more. The 30mm opening I currently have leaves almost no room for movement so at least with 60mm I should have a clean 15mm in any direction.

The Pico will mount Arca-Swiss R-bayonet lenses, with the 010907 Pico R-mount adapter lens board. The R tube diameter is approximately 81 mm internally, which provides a large opening to reduce some mechanical vignetting and allow more shift movement. R-mount tubes can be purchased separately and multiple R tubes can be stacked. There are also flat R-boards which allow easy mounting of lenses and available in size 0 or size 1 openings. The flat R-lens board bayonet mounts to the R tube.

Rod has mounted and infinity focused a 210mm Rodenstock for use on the Pico using R- tubes from his own R lenses. These are manufactured in a variety of lengths, as each lens in the R system, 23mm - 210 mm is calibrated with it's specific tube length. It would be good to write a letter to the product designer and simply ask, as they are generally open to feedback. If Arca understands your intended use, they may be willing to expand the system with parts that are currently manufactured. However, mounting the lens so far forward of the tilt and swing mechanisms, isn't ideal and why Arca doesn't recommend it for general use. But, if using a long lens to shift only, they may understand the need.

Rob - there is currently an M39 Pico B-board available and stocked.

Scratch that, I was going on memory. You are right, the opening is about 60mm.

Be aware, if you happen to use any V-system part in the adaptation path, the opening of the V mount is greatly reduced to about 40mm due to the cocking mechanism for the V-system leaf shutter.

I have mounted my 180 mm Sinaron-S to Cambo Actus using Hasselblad V extension tubes. They have "ceilings" at both ends. The opening in those is ~46mm X 46mm with rounded edges. I can shift my Sony 15 mm down and 20 mm left/right without vignetting. So I guess you can shift your back 15 mm to any direction.
You can also use Hasselblad tubes for close up photos. Those ceilings work like Rob's baffles. I have also removed that cocking system in one tube but then there's a little more flare.

This is a 55 mm tube.

The cocking mechanism is not incorporated into any of the parts used for lens extension - this includes the Pico adapter and RAF adapter. . A moot point - even if the the cocking mechanism were considered it only affects one side and only reduces the opening in that direction by 7mm.

Yes, it's so in Hasselblad camera body and lenses. But in the extension tubes there are those plates with a square opening. The square is 46 x 46 mm. If you have weiling flare with that raf-adapter I recommend you to test a 21 mm tube to cut the flare.

... it caused vignetting to me (I use the V mount as a "universal adapter" for my Cambo), so I thought it's worth mentioning. I was trying to make clear that this only has an impact if any V-item (meant for the V-system's leaf shutter line, such as extension tubes, bellows, ...) is used in the adaptation path. Glad you didn't run into these issues.

The Arca Swiss version of the adapter doesn't have a cocking mechanism and the opening is circular and just shy of 60mm.

Hi Lonna,

Have you been able to order R-mount tubes separately? I've tried and they wouldn't which is why I came up with a DIY solution. Maybe they have changed their stance on this.
