    Re: Sony a900 ads leaked

    Just saw in my local newspaper that it will be demo-ed at the Sony center in Stockholm today. Expect to drop in there about 2 hrs from now...

    For those of you living in the time zones behind: just :sleep006: for some more hours....

    Here are some results from someone using Therappe (never heard about it, but it apparently works):



    Here's another one. This one is down-sampled to 12MP, to match the resolution of the D700. Apparently, the reds had to suffer to obtain the noise-free image, but this is starting to look good:

    Re: Sony a900 ads leaked

    One thing to remember when studying high-ISO capabilities, is that the Sony has IS that works with all lenses, including any fast prime. That obviously makes taking photos of slow-moving subjects in low light possible at lower ISO than with a Canon or Nikon, since none of those two have lenses with IS/VR shorter than 200mm that are faster than f/2.8.

    Sure and the smearing effect on the foliage looks obvious.
    Looks like 1600 iso is not the Sony's cup of tea so far.
    Thanks for sharing Jorgen.

    Thanks Jorgen. it does seem that the high mega pixel from the A900 is not really doing justice at ISO1600. The d700 is by far achieving much better pixel quality.

    Guess we wont be using the A900 for low light indoor action. It does not matter how much built in image stabilization there is if the subject is moving, higher ISOs will be called for.

    Re: Sony a900 ads leaked

    The ONLY interest I have in this camera is the AF Zeiss lenses. I see it as a contender for replacing my now sold Leica DMR/9 and lenses, and now sold Canon's with 85/1.2L and 135/2L.

    I'm not necessarily seeing it as a system replacement, but more a supplement to the Nikon system in my wedding roller... and a nice portrait set.

    If Nikon were to offer a 85/1.4VR and 135/2VR is the same manner as the more recent 100/2.8VR Macro ... this Sony consideration would be tabled in a heartbeat.

    I have three concerns about buying into this proposition ...

    Lack of fast Zeiss primes below 85mm ... which hopefully would NOT include their 50/1.4 which in every iteration (C/Y, ZF, and N) exhibits the worst Bokeh of any 50/1.4 I've ever used. The expensive Sony 35/1.4G is not on the list after seeing shots at f/1.4 that are unacceptably soft. So a Zeiss AF28/2 or AF35/1.4 would make it more attractive.

    Any mention what-so-ever of crappy noise performance ... something that has plagued the Alpha series to date. Clean ISO 1600 is a must ... which is something a D3/D700 can do standing on it's head. I also personally could care less about this being 24 meg. and would have actually been more interested in FF 12 to 16 meg. with larger pixel sites.

    Service ... perhaps the most important of the 3 by far. IMO from other experiences and looking at their history, Sony's corporate culture is a model of arrogance that Canon can only stand back and admire. I can say that I KNOW for a fact that Nikon's service system is excellent ... even though I've not yet joined the Professional version. I will NOT subject myself to anything even remotely akin to the nightmare of Leica service ever again. IMO, Sony will need to provide a Pro level service experience for this camera.

    Other remote concerns: the modo stupid proprietary flash system that requires an adapter to use a PW or any radio system ... and lack of rental gear.

    I have to agree with you on the samples, they leave quite a bit to be desired, jpg or not. I really don't see what's so special about lower iso images either, I guess you haven't picked up your S5 yet.

    As far as a studio camera goes why bother with this, you can pick up a Kodak slr/n for a lot less money with much better IQ for your jewelry shoots. But and this is a big but, I'm not so sure if you want all that sharpness for silver products that are riddled with casting and finishing problems. My other question is if your style of shooting is the classic, sharp, detailed look then 35mm isn't going to cut it with its shallow dof and full frame is even shallower...

    Re: Sony a900 ads leaked

    I see this as a great backup to my MF system and having at least one DSLR to shoot some stuff. But I would like a clean 1600. So far i guess i am still leaning the Nikon way. My only real reason would be high ISO stuff since i have my 800 limit on my Phase back. Okay Canon show me. LOL

    Re: Sony a900 ads leaked

    I will probably buy the best ISO 1600 camera, and if I need a tie-breaker, look at ISO 3200. Unfortunately, I suspect that will leave this Sony and its Zeiss AF glass out.

    One thing on the above 1600 frames, it appears the D700 shot is maybe half a stop brighter, and this could be affecting the reds. Could also be a bad camera profile since this is such a new camera...

    Re: Sony a900 ads leaked

    David, I hear what you're saying. Problem is that sometimes, resolution is the only thing that counts, and if that is what my clients want, that is what I have to deliver.

    The S5 is decided anyway, but I'm on my way out of town again, so it's still on wait

    I understand, I was in that industry for most of my life and am very familiar with the characters in there, the kodak slr/n is really great for that. It has fantastic color and great resolution and you can get them for a song these days.

    What is bothersome on the resized images is the color bleeding. The yellow paintbrush and the red diamond on the labels both "extend beyond their borders"

    Re: Sony a900 ads leaked

    I've played a bit now with the Sony RAW files from Imaging Resource. They open with Raw Photo Processor, which is free/donation-supported (Mac only).

    The thing about comparing Sony RAW (ARW) to Nikon RAW (NEF) is that we have very limited choices for converting the ARW files (just Raw Therapee for Windows or RPP for Mac since there is nowhere to download Sony's app), whereas we have tons of options for Nikon. Capture NX2 does a remarkable job of eliminating chroma noise during RAW conversion. I don't think anyone is doing justice to the Sony sensor in these preliminary comparisons.

    Sony hasn't done themselves any favors by using lousy in-camera high ISO JPEG conversions in this camera.

    Here is an Imaging Resource ISO 6400 A900 in-camera JPEG that looks awful. I took the corresponding RAW (ARW) file, processed it using Raw Photo Developer (Mac only), used Noise Ninja (sacrificing much of the detail especially in the red fabrics), and then did a quick levels/curves adjustment to try to roughly match the in-camera JPEG brightness. This is the result. With a RAW processor that I've actually used more than once, I'm sure I could do much better.

    Amin:

    It is amazing to me how similar your processed version of the 6400 shot looks to drum-scanned color negative emulsions, and it doesn't look digital at all...

    This could be way cool!

    Hi Jack,

    Can't say that I've ever seen a drum-scanned anything, but I agree that the processed RAW looks pretty natural when viewed from a reasonable distance.

    I think we'll be seeing plenty of good high ISO work from the A900. That said, I'm sure the Canon 5D replacement will offer much better JPEG processing than this. If the Canon is 21 megapixels and $3K or less, the A900 will have stiff competition.

    The Sony image was converted from RAW. Sony apparently has a major problem with their in-camera jpeg-converter. Strange, since they do have some experience in this area, more than anyone else probably.

    All the debacle around the conversions (and there's a lot going on across the forums), and all the different versions of this particular image, indicates to me that the sensor is actually ok. It's a question of finding a work-flow that optimizes the final results.
