Phase One A Series

Nice to see that the Alpa mount 35mm f4 Rodenstock HR-Digaron-S getting a new life as the 'Alpar 4.0/35mm' in the new A series, it's a great lens, needs no CF, and a full stop faster than the others. Seems they are making it the mainstay of the 'A series' system, and that's probably a wise choice.

Bit shocked by the prices though + can't help but think the FPS would have been a better base to build a mirrorless MF system upon. But... they obviously feel otherwise.

Notably, Phase One seems to have removed any "mirrorless" references, which never should have been there to begin with.

Regarding the 35mm HR Lens, it's a perfect match for the TC, as it has a relatively small image circle, but good optical quality. I find though, that it will benefit from an LCC even without any movements.

Steve, it is still there. This is from the brochure and also on the P1 website.

"The A-series combines the finest components across lenses, mirrorless body, digital backs and software. "

Oh well.......wishful thinking.

Say you have a IQ260 currently with Contax or HB mount. Can the A-Series package be replicated by purchasing an Alpa TC with one of the three lenses and a firmware upgrade on the back? Would PhaseOne do the proper mating/shimming of components so that the back can still be used on the Contax/HB?

On the other hand, without movements, is this really worth it?

Can you replicate the bundle yourself? The answer is yes.

For the TC you would just buy the correct adapter plate for your back which will come with the shim set so that you can adjust the back to the body/lens etc if necessary. The shims are in the adapter plate and don't affect how the back works on other systems.

Is shimming worthwhile? If you want accurate infinity and subsequent distances on the lens then yes it is. Movements don't matter in this respect.

In the scenario you describe, the same components can be purchased (minus the A series Branding) from any authorized Alpa/Phase One dealer. Currently, the firmware that provides the embedded LCC functionality is exclusive to the A Series Digital Back Products. The shimming process would be provided by the authorized Alpa/Phase One dealer. Understand that Phase One's role in this is specifically only in the event someone is purchasing an A Series package. In that event, Phase One would be shipping a pre-shimmed Alpa adapter for use with that specific A Series Kit.

If one were to purchase an Alpa TC and any lens for use with their existing Phase One digital back, or choose to purchase the Phase One digital back separately from an A series Kit, the authorized Alpa/Phase One dealer would take care of any shimming. This would be the case if someone wanted to purchase any Alpa camera, an STC, a Max, etc.

Whether an Alpa TC without movements is worth it, is up to you and what you wish to accomplish. We often find an Alpa TC is an addendum to an Alpa system. It could be a starting point, or an expansion. Someone may have an STC, or a Max, and want a smaller package to pair the outstanding Schneider/Rodenstock lenses with that can utilize the same digital back (and interface and lens adapters) that their other Alpa camera can use. But certainly as a stand alone camera, it produces the opportunity as an amazingly small, lightweight, extremely high quality capture device.

The A Series announcement was something that we have been internally considering for some time, as there was the perception of some smoke and mirror, and also facts were not being made readily available. This is why we have not jumped in with both feet until now, when we feel there now exists some clarity.

As a Phase One and Alpa dealer, we offer our perspective for the A series products below:

What Steve said :thumbs:

The new firmware with my TC/23HR could be very useful. With / without center filter btw?

*Calibration* is very important. On an Alpa this is done with a mechanical metal shim ("shimming"). On Cambo this is done by an adjustment of the lens helical. On Arca this is done by determining a numerical offset.

Any good tech camera dealer is more than qualified to calibrate any tech camera. It's not a complicated process.

From the excellent CI synopsis: "Today, this firmware will not be available to existing IQ2 customers. This may change and with pressure from current customers it just might."

Hoping for change!

Agreed. We've been lobbying this direction on customers behalf as we feel it's more in line with the "open platform" mentality.

Though the current implementation is pretty limited (no allowance for movements) so is really only applicable on the TC. The Arca and Cambos "travel camera" bodies (Arca Factum or Cambo RC400) both have built-in movements.

Still, in the future one could imagine expanded functionality like entering the movements and having the LCC selected automatically.

This is just the start, wait till they get the FPS into the equation. And I bet they will sooner than later.

Judging from the pictures of the A kit it looks like it is possible to chose "Other" under lens selection. As I have stated quite a few times, also directly to Phase One, it would be really nice to be able to manual enter lens/shift/rise/fall and it really should'nt be too hard to implement that in the IQ firmware, including the firmware for the IQ1 backs! :lecture:

Of note, as we've pointed out on our Capture One 8.1 Release Blog Entry the Rodenstock 23HR, 35HR, 40HR, 50HR, and 70HR are now supported in Capture One 8.1.

This is not limited to users of an Alpa A Series but works just as well for Arca/Cambo/etc since they are all use identical optics. This includes distortion correction without leaving raw, with optional offset for rise/fall/shift (manually entered) which is useful for tech bodies with movement.

Didn't know that. Awesome!

Rodenstock support in C1 is excellent news. Hopefully the 32 and 90 will be added soon!

Kind regards,

Great write-up Steve, but one question does still remain.

Which sync solution is included with the A-Series?

Kind regards,


Gerald.
