for me the biggest advantage of that lenses certainly is that they can be used at open f stops and remain sharp.
together with the possibility to use them without center filter it seems to be a plus of 2 ( xl lenses without cf ) to 4 stops, xl with cf filter ), although should not be a problem to use the 58xl without cf also,- isnt it? in interior or night shots not so little difference.

things are changing...
when i started to work with sinar and gottschalt i remember that i was one of the few people here posting and using that systems, at least for architecture. than discoverd foto-z in one post of mine the appearent centerfold issue, i was not aware of that at this moment. stephan and me already have been working about tweaking the colors of the e75, ( which i did not liked too much after receiving it in april ) and so stephan went on improving his brumbaer tool and wrote the code for removing this cf thing. following here have started big and large posts about centerfold issues, workarounds and solutions by the two companies who use the same dalsa sensor, leaf and sinar.
one year ago you found nearly only phase and leaf guys here,- now sinar users seem to be very present. lets see how it will go on.... these things are changing fast. i am very active at the moment here, but this can change also because just sharing can become a little bit boring and too time consumptive ( as it was the last days- anyway i am in a kind of holidays ...), than will come the next guy who has fun in beeing present here... and so on.although many many people are reading these forums, not so many are writting much and even less have much personal experience,- so just a few people can influence the appearence of a "little" forum a lot. for good or for bad is another question..... but the things are changing and so they will do again.

Interesting times!
I have a question regarding the 28HR used with the Cambo WDS.
Because the lens is top heavy,could the way Cambo's mounts their lens in the camera body effect the?
Is it holding the lens barrel perpendicular to the sensor plane and thus the plane of focus parrallel to the sensor plane?

Also I have a question regarding using the centre filters.

Isn't there a way in post to remove the vignetting so you don't have to use the centre filter?

Regards,
Willem.

i dont use a center filter on any of the HR lenses, i believe that sinar/ rodenstock even dont provide one. i use for all shift-camera shots brumbaers dngprogramm, applying white files to the shots.
in these workflow the vignetting and color casts are eliminated by inverting grey files.
i shoot at the set before every motif a white reference with an grey-transparent 10x10cm plexi. the dngconverter creates white references out of these files and apply them in a batch to all the files meanwhile it writes the dngs.

Rainer,
I was talking about the Schneiders that need a centre filter.
I'm fully aware that the HR don't need centre filters.

All I wanted to know,if there was a way NOT to use a centre filter with the 24XL + 35XL
and get rid of the vignetting in post?

BTW,I ran all you test through CS2 Lens correction and it's very easy to correct the distortion.

How's the holidays?
Looks pretty cold for Spain,I see people with coats!

Regards,
Willem.

During the presentation of CaptureOne, I do believe I’ve seen the vignetting removal tip in CaptureOne but I could be wrong. I will check that again.

Interesting question, but I don't understand what exactly do you mean?

ALPA12 SWA is lighter then Cambo WDS, should I be concerned?

Danijela

Att: Rainer

I know you don't use any center filters on your lenses. How do you protect them from scratches? are you using UV filters, etc.?

Regards
Danijela

The Cambo Wide DS is an analog camera design that works with the Schneider 38xl to 150mm lens.
In the middle of this line up is a Schneider 72mm xl & the Schneider 90mm (655grams with no lens mount) which I use for film and digital capture.
I don't think the lens mount can effect the geometry between the lens and the ccd as this camera
robust and built solid. Notice there are lens guards on the lens mount to assure that the perpendicular geometry is not compromised while handling or storing the lens.
I realize that the 28mm HR weighs over 900 grams so it is possible that the weight could affect the helical focusing mount.........

The Cambo Wide Digital DS is the same camera body with a recessed film/ccd plane...this enables focusing the Schneider 24xl digitar. All the lens panels and film panels are interchangable allowing you to make digital and/or analog captures.

hmm... i never used any uv filter even on my old 35mm leica m4p or on any other camera...
but i never scratched any front lense, although i use my cameras rough .... sometimes.

I see. I would definitely use some sort of protection, I guess it depends if you
are in a windy situation, sand, particles etc. but with the 5K lens I would for sure consider it.

One more question,
Did your camera came with the custom made head attached to it, or are you using something else? with what kind of tripod?

Regards
Danijela

So you are rough?
I like that in a man, can you elaborate a bit more?

Shara

Danijela,

Have you made your decision on a digital back yet? I think I have pretty much decided to test the Leaf and Phase One. I would love to get to London next week, Yair sounds like a knowledeable individual, I would like to meet him. Maybe have a pint or two.

Shara:

I'm glad you're here.

We have to get more women on this forum.

Not yet, waiting for more phone calls.

Some of these distributors are not to blame, it is just the fact that their factory responds
are not efficient enough and therefore the product suffers and erupts in commercial failure I guess.

All of the products seem to be fine more or less. Basically, I am going to give another try to Leaf even though I was against it for the obvious reasons.

............. P45+/P30+ » would be Practical Decision
............. H3D » would be Conservative Decision
............. Leaf Aptus A75 » would be Funky Drummer Decision
............. Sinar e75 » would be The Future Decision, with the ? mark and I only say that because of their M System History

So the question is, where do you/I fit?

Danijela,

Just a precision and information concerning the "Sinar m" system: this camera system has never been developped with the intention to get into the Fashion, Portraiture, Wedding and Architecture or Landscape photography market.

It was developped and built with the intention to provide an open system with multiples (automated) functions in institutions like Museums, National Art Galleries, Libraries, etc ...: that are the markets where the Sinar m system is used.

Best regards,
Thierry

i use my gottschalt with a mamiya head.

about the 28hr price and protection:
.... the 28hr isnt cheap but the back did cost 5 times more....
the camera nearly the double....

so in relation it is as to use a m6 leica wih a $300 lense.
what a crazy mf world .....

better not to skip the tripoid.


whats wrong with the sinar-m danijela? i was working with one and its a nice tool.

Basically that is what I thought, too many products with multiple options designed to fit a single corner.

Regards
Danijela

I thought It’s custom built by Gottschalt.


With regards to the Digital Back, as long as the chip is clean I’m OK. With regards to the
Lens, if you see the mark on the glass of 5K lens, surely you wouldn’t celebrate, that’s all.


I agree.


I thought I’d ask, since everything with regards to your system is more custom then ALPA or more custom then any other system I know.


Not much, jut the fact that it's not commercially viable as it could be, with only a few additional, desirable upgrades. Otherwise, I guess it fits the bill or am I wrong in saying that?

Regards
Danijela

yes my system, including me, is very custom made. but gottschalt was merciful and used standard screw threads...
my gottschalt is based on the di30 ( although it is thinner ), the sliding back is custom made.
at the time when i ordered it there simply was noone offering a camera with similar possibilities,
not sure if you could get anotherone now with sliding back. anyway.... it was a long and little bit spiny way till i had it.

about the sinar-m... i am not informed about their actual prices, but main critic i listened was about that. i think ALL the mf prices for new gear are very high, and if you see and feel a H3 and if you see and feel a sinar-m in relation you just wonder that it dont cost the double as it already does. same about the alpa ( which is made by seitz )..... this swiss guys really manufactor things on a very high level. i was reading that the trains in swiss delay in an averadge time of 1 minute.
i think in germany they delay 20min / average or so.

on the other hand many people go crazy just with the announcement of a HY6/AFI camera and it seems so that noone thinks that such a system will cost with 4 or 5 lenses probably 20.000 $.

again its the same than with the HR/XL lenses discussion if it comes to the point that the HR lense cost 1/3 more. in relation to the, already so high prices, this should not be a big factor for any decision here, thinking that for architecture this is the key optic of a system in some aspects.
noone asks for the price for the new 28mm h-lense? everybody is thrilled that the h3 will "correct" it automatically.... what you easily can do also in photoshop with 1 action.

i am thinking economic also, one reason i am very happy with my contax 645 which save me 15.000$ in an easy way and i cannot see what this camera cannot do in comparation to H1/2/3//HY6/6AFI//6008. my two old 501 hassies are sleeping since i got the contax.

but if i would think in one of the new cameras i would consider also the sinar-m.
maybe too less lenses exist for it,- but i dont see the price more crazy than any other of the actual made mf system camera except mamiya ( you can adapt many different mounts and lenses to the -m. although not sure about that ).

hi Rainer,

Existing Sinaron DIGITAL Zeiss AF lenses for the Sinar m are:

- 4.0/180mm; 4.0/120mm Macro; 2.8/80mm, 4.0/40mm

Also:

- Hasselblad V lenses can be monted with the "Lens Module Hasselblad V"
- Nikon lenses can be mounted with the "Mirror Module Nikon Lenses"

Prices have been reduced starting 2007 by minimum 20%: available and on request, from any Sinar distributor.

Best regards,
Thierry

I would have to agree that Contax 645 is perhaps the most versatile system which has AF lenses range from 35/3.5 thru 350/4 and a tele-converter, with the MAM1 adapter. I have all the 9 lenses and love each of them. It works with all Hasselblad lenses either FE, CF, CF, CFi and CFE. It is perhaps the most opened platform today in medium format with AF option. Many people has seen the end of Contax line, I am still wishing Zeiss will somehow put up a trick to have Cosina to produce it, or or that matter, anyone who can continue it.

I guess it makes sense to say that, but the fact remains, Cantax was put to rest
and personally, I don’t' have any favorites attached, but that's a big NO for me.

I am just wondering, when Canon made a commitment to Maria Sharapova for US$ 20,000,000 so that Canon can sell their little PwerShots Cameras, why couldn't they purchase CONTAX for 10,000.000?
