Title: 35mm Lenses: Cambo Wide DS vs Medium Format
Post by: clawery on February 04, 2008, 12:13:19 pm: Alright, so we are a bit masochistic here at Capture Integration, but we are going to post another comparison. This test will show you a P45+ on a Cambo Wide DS vs other medium format systems.

Alright, so we are a bit masochistic here at Capture Integration, but we are going to post another comparison.
Thanks Chris for taking the time to do this. It's great to see these comparisons - it gets us away from the purely subjective opinions.

Now, if the MF camera isn't a Mamiya 645, then it sure would be nice if you could add a Mamiya to the comparison :-) Also (you knew there would have to be an "also"), it sure would be nice to see the same shots with a 35mm Rodenstock HR lens on an Alpa kit (I believe you guys sell Alpa's).

Thanks again.

We are an Alpa dealer and I'll have to see if can add it to the mix in our next test.

Post by: MarkKay on February 04, 2008, 05:26:59 pm: Chris. I do not believe there is going to be too much issue if you list which MF camera/lenses you used for the study. I think most people have seen some data suggesting that the digital/digitar lenses give more resolving power with the higher end digital backs.

Title: 35mm Lenses: Cambo Wide DS vs Medium Format
Post by: Graham Mitchell on February 05, 2008, 02:27:10 am: I compared the right side window at f8 and it wasn't even a close race. The Digitar was better in every way and seems to be taking full advantage of the P45.

In fact I would bet that a P25 plus Digitar would give a better image quality than this MF camera and P45 combination.

Just another reminder that it's not all about megapixels

hasselblad? and was it (software-) distortion corrected?
(I am asking because I am in the market for one)

yes but the whole zones downside including the lower left and right corner are better
from the "normal" 35mm, including the center of the image. strange.

if it´s the mamiya, then it doesn´t show the same amount (of barrel) distortion my old, manual 35mm has. and edge sharpness seems to be better than my one. (which seem to coincide with what somebody from mamiya germany told me last week: that - even thought the lenscalculations are the same from the old 35mm - they probably use a newer kind of glass for the af 35mm. or perhaps I just have a bad sample lens.)

looking at the pic again, the lack of distortion and of (stronger) CA would indicate to me that it´s the - perhaps software-corrected - 35mm hasselblad lens.

Post by: eronald on February 05, 2008, 06:37:02 am: Anyone using wide-angle solutions should investigate flare issues carefully. I've had people email me for profiles, when in fact careful evaluation of their files showed they had serious flare problems rather than defective colorimetry. One should not confuse flare and reduced contrast with bad resolution.

From the referenced Capture Integration web page -

"CWDS lens was a Schneider lens: APO Digitar f5.6 35mm XL-102deg MC "

we are wondering about the other lens, not the one on the cambo.

Post by: jing q on February 07, 2008, 04:41:30 am: has it been other people's experience that the edges on the rodenstock and schneider lenses tend to be less sharp than the normal medium format lenses
I'm using a rodenstock 45mm digitar and it gets abit soft on the edges compared. the center area is sharper than my mamiya 45mm however
Title: 35mm Lenses: Cambo Wide DS vs Medium Format
Post by: vgogolak on February 08, 2008, 01:34:56 am: Same with 35mm digitar vs Contax 35mm;
digitar sharper in center
Contax a bit sharper at edge

however, both fall off
the Digitar center though cant be beat on the alpa with P45+

Regards
Victor

Post by: vgogolak on February 08, 2008, 01:42:28 am: BTW, the reluctance to name the 35mm lens is just suspicious; it leaves open the test to question;
if the M then of course, reluctant to hit a current 'for sale system'
if the C then might have shown it, discontinued, no?
if other then why?

the MF 35mm lenses are not the same. If you cant name it, then all we know is the Digitar is better than ONE of them , in the center.

Post by: RobertJ on February 15, 2008, 09:31:07 pm: Aren't the Rodenstock HR lenses far, far better than the Rodenstock Digital Sironar and Schneider digitar lenses?

At least that's what I've seen so far. If I had a P45+, I know what lenses I would use...

No, not to my findings - I tested both Rodenstock HR lenses and Schneider Apo-Digitars and my bag is now full of Schneider's, you will find the quality very alike, I think it will come down to personal preference in the end.

You can see some more details here, read Rainer's and my post's : [a href=\"http://luminous-landscape.com/forum/index.php?showtopic=22266&hl=]http://luminous-landscape.com/forum/index....topic=22266&hl=[/url]
