Phase One News: XF Body, IQ3 backs, 35LS, 120LS, C1 8.3, Website

Doug:

First of all, nice shot, love the composition.  Very impressive indeed on the corner, as a chaser of the sharp corner I can appreciate the details.  I would like to see some shots closers to F3.5 to F8, same type of setup just to see if the corners hold up as well. Lots going for this lens for sure love the 77mm filter threading. 

Hope to see some comparisons to maybe a 35XL or 32 Rodenstock, same F11, then around F6.3 or so, with no tilt on the tech lenses.  The new 35LS may have a better hyperlocal distance than the Schneider and less Mustache distortion than the 40mm Rodie or 32mm Rodie. 

Just wish this one was around a few years ago.

Paul

Thanks Doug L

The photographers who have Hassy glass have some good options as well.  A test shoot comparing the Phase One  XF body to the Hasseblad H5X  body would be lots of fun.

Jeffery

Thanks for sharing the LS 35mm file.  It looks very crisp. Is that your summer home?

I second this!

A comparison in studio (Focus systems) and in the field (Edge quality of the 35mm vs the Hassy equivalent) would be pretty awesome.

The photo is by Niels V. Knudsen the Image Professor. But it's not either of our summer homes  .

If either of you (or anyone else) would like to come to any of our US XF Body Events (NYC | Houston | Dallas | Boston | Philly | Chicago | D.C. | San Fran | Miami | Denver | Birmingham) we'd be glad to schedule a time within the day for you to spend meaningful time with both an H5X and a XF and make your own assessment. Shoot us an email so we can coordinate on when, during the days schedule, would be best to set that up.

I've seen some frames at f/4 and it was surprisingly good.

As you can imagine we will put it through its paces as soon as we get our first copy.

The filter thread is 105mm, not 77mm. Full (correct) specs are here: Schneider LS lenses. Phase One just redid their full website (at the same time as 3 new backs, 2 new bodies, a new C1 release, a new case, and a variety of smaller things) so I guess that page just slipped through the cracks.

[Doug Peterson]

Very promising indeed, how come you reach such a depth of field Dough?! As if they are merged pictures with different focus point! How much technical camera, say Alpa/Rodenschtock, can get better than this really in terms of edge to edge resolution and  sharpness?

It's a single frame. But the XF has a Hyperfocal focus mode which can automatically bring the lens to the exact hyperfocal point of the lens (based on your own criterium for how strict to be about infinity sharpness) which makes it easy to maximize DOF.

This shot was by Niels Knudsen of Phase One, not me.

In fairness a tech camera Arca/Cambo/Alpa etc provides rise/fall/shift/tilt, and I do think if we made a direct comparison (which we will likely do when we receive our first copy) we'd find the 32HR does edge it out very slightly in corner sharpness. However at some point you're arguing which super car does 0-60mph in 2.8 seconds vs 2.9 seconds; either one is fine by me .

Image quality of the new 35mm lens looks amazing compared to any of the Mamiya/Schneider 28mm's and the previous 35's SLR lenses. It wipes the floor with those lenses. At least from looking at the linked image.

Thanks, do you know the f number used for those pictures please? f16 maybe? I can't find it in their EXIF

[N Raziel]

Hallo,

First of all, Sorry for being off topic...

I would like to know if there is any possibility for Mamiya version of this body?
What is the future of Mamiya system?

[Theodoros]

Three more questions please:

1. Will the XF body work with any current third party backs that are made for m645 mount? (eg. the Sinarbacks)
2. If not, will it allow third party backs to work on the platform via a new compatible interface plate?
3. Will the XF allow for multishot captures with a multishot able third party back?

Thanks...

f/11

[alifatemi]

f/11

Such a huge depth of field with f/11?! even using hyperfocal, its unbelievably phenomena! Or do I miss something?

HF is about 6ft at f11 for 35mm (.03mm CoC)

[chrismuc]

Acc. my DoF calculator the hyper focal distance for CoC 0,03 mm would be 3.64 m or 12 ft, not 6 ft.
I think CoC 0,03 mm is not sufficient. I suggest twice the used IQ180 pixel size = 0,01 mm. This leads for 35mm at f11 to a hyper focal distance of 11 m.
The bottom corners of the two pictures are much nearer than 11 m and therefore the sharpness seams quite unreal. My guesses: either due to the extreme C1 sharpening or if was f16 plus sharpening. Or two pics near + far combined?

You are mixing up HF distance with near-point for DoF.  Yes, the focus point is 12 ft at these settings, this gives you a DoF from 6ft to infinity.  Similarly, if you use .01 CoC, with a focal distance of 11mm, your near point for DoF will be about 12 ft (4m), not 11mm.

Having said this,  in reality you are not going to see much of a difference between .03 and .01 from centre to corner.  Field curvature, and most of these wides tend to pull DoF in at the edge of the field, further gives a perception of increased Dof in the corner.

[chrismuc]

:: jsiva
reg. DoF near point and HF distance: ur right! sorry, my mistake
reg. potential field curvature: that could be the reason ... just in that case, it would not be sharp at infinity in the corners at the same time, but that cannot be examined by these two samples

I'll be mostly absent from the forums for a few days as we prep for and run our Phase One XF Event in NYC. If you have pressing questions feel free to post them here, but you're also welcome to email us directly.

As an influential dealer, I'm disappointed that DT didnt push Phase One to continue the support for Contax.

Hasselblad V is a dead end system, and I'm relatively sure there were more Phase back sold for Contax than Hasselblad V (please correct me if I'm wrong) and the continuing demand is much greater. Yet Hasselblad V is still supported.

The number of orders for Contax trail even Hasselblad V today by a good margin and so, bring up the rear for interface choices (and after many years of holding steady, Contax orders have declined quite a bit the past 2-3 years). It's too bad, but we all knew this day was coming at some point. I'm actually pretty surprised and pleased that digital backs have been produced for Contax as well as Hasselblad V for this long (10 years after the discontinuation of the camera).
