Interesting new information on the S2 in this latest issue of LFI. Only had a chance to skim it briefly but there is information on the Maestro processor and pictures of the circuit boards. Look nice and steals my thunder for an "anatomy of the Leica S2" thread...

 

Not sure we all would let you even attempt it without sending a white truck out to your house with guy's in white straight jackets and a custom made jacket just for you with a Red dot on it. :D

Well, an interesting article describing the camera architecture, the image processing pipeline and the development process. Interesting comments too that general purpose DSPs, such as we have in the M8, are not cut out for duty in a digital camera; also, that good quality JPEGs are difficult to achieve in-camera. Take the two together and it's easy to understand why the M8's JPEGs are not its grestest strength.

 

Seems clear Leica is really focussing on honing their in-house skills and Fujitsu is proving a good partner. Makes me wonder what, if anything, has come out of the Jenoptik agreement.

 

I expect the combination of the S2's electronics and firmware, the Kodak sensor and Leica's optics is set to be a killer combination. All they have to do is sell it.

There are some numbers on the framerate now. The camera can apparently shoot 1.66 frames/second, and has enough memory for 10 frames. However, the frames are getting processed fast, and so by the time the 10th is shot, the first few are already processed and written, so the real buffer size will be something above that. There are too many factors mentioned to calculate exactly what, but they state that the difference is significant, so perhaps 15 frames? Quite a nice system. And it can write JPGs to SD and RAWs to CF at the same time. Very nice.

I still don't get the point of the JPG-capability in this segment.

JPGs are per definition not professionally usable (bit depth, post-processing...), are there really clients that want some "quick&dirty" JPGs of a photo-shooting while the photographer still processes the RAW-files to perfection?

2 reasons really fast review for tethered work although C1 uses the raws. Second external Epson travel units only see jpegs which is a good for viewing besides storage images n the run. Also clients can make there selects quickly as you can show immediately in any web browser or almost any program . So you can quickly upload to a .mac account or something like that. I know that was 3 but there is use for them and ultimately could serve as a backup if everything gets lost. Okay that was 4 still on first espresso. LOL

Mine shows RAW files from my Canon 5D. Though I admit that it's unlikely that Epson will update the firmware to show RAW files from the S2.

 

I don't know if the later models are better, but the P2000 that I have is slooow when copying cards. Plus copying files drains the battery very quickly.

Interesting it see's the canon , never before it saw the DMR or M8 and maybe some of that has changed. I still have yet to buy one of these things. I take the laptop when it is a big job.

My first beauty national ad photographed 5+ years ago with a Fuji S2 was captured in JPEG format, and only after I got "permission" from my retoucher (one of the most finicky in NYC, who prefers to drum scan 8x10 film).

 

Last month, I converted retouched (Leaf Aptus 75S) TIFFs to JPEG 12 before Zipping over to German glossy magazine. They used one of the photos on the cover as well, and I receive many compliments on the quality.

I think there is a continuing myth about jpgs.. sure I would rather work with raw.. but for many years my stock agency has only sends out images to clients in jpg.

Erm, shouldn't they perhaps make it first? ;)

 

well I am giving them the benefit of doubt that it is being made.. but then there is the tiny issue of us buying it.. the quote "champange taste with a beer budget comes to mind"

I think there will be thousands who would love to own this camera...but..can I? that is what the biggest hurdle will be.

Converting the final image to JPG to send it over the internet might be acceptable (but when I insist on 37,5MP + Leica-lenses I would also insist on TIFF...) but shooting in JPG is a completely different thing and that's the point, you practically throw away 80% of the information the sensor has captured seconds after you captured it and the JPG tries to hide this fact more or less successful...

 

Maybe it's really simple to implement the C1-conversion into the S2 with it's powerful processor but they shouldn't waste months of firmware developement into this function...

Well I agree on the first part but the second part you simply need to have the S2 completely optimized for C1. Going back looking at C1 and what it does for the DMR and M8 is frankly what makes those camera's what they are since the raw processing of those files is the best in my mind with C1. Plus as a Phase One back owner the reason I chose Phase was how powerful the Phase backs are with it for raw processing and tethered work. Nothing does a Phase file any better period. So time spent in c1 is worth it without a doubt . The beauty here is leica does not have to really deal with it Phase does and optimizes the files for it's program. This process has not much really to do with leica in there build process and won't slow them down. leica said next summer with plenty of elbow room in there to get everything correct before release . Please trust me because i do know this it will not be out before it's time and ever i will have it's dot on it on release.

 

Frankly and to brutally honest without Phase involvement with the S2 in the C1 process it will just be another piece of crap file coming out of a digital box( i mean this in a nicer way than said). I would not be remotely interested in it without Phase on the processing side and the S2 WILL need tethered support if it wants Pro's shooting this cam. All other raw processing from the MF backs is designed for there back. Leaf, Sinar and Hassy all use there own software and only one back OEM has a public program and that is Phase. Adobe has no tethered support for anything, nor does raw developer so there is only one real choice for Leica and they already have a nice relationship with Phase and in my mind the more they tap into that relationship the better this product will be.

 

Now I will freely admit my two most favorite camera makers and raw processing. Believe me they both know it too. I have a very good relationship with both companies.

This is not true. JPGs are often the final step in the pipeline, not just some amateur thing. If the exposure is correct and little or no work is required to reach the final image, JPGs could be good enough. This is true for many fields. RAW is really needed where you want an insurance against errors or later heavy corrections.
