TVSD vs SONYbs DSCV1

After comparison on the functions and also made reference on the test result from web site, I finally decided to buy Sony¡¦s DSC-V1 in lieu of Contax¡¦s TVSD which save me about US$170. But there is no carrying case included which cost additional $US25 for a Sony case. You could see the web page { http://www.steves-digicams.com/2003_reviews } for full review for both models. Test result from web site gives Sony ¡§excellent¡¨ image quality but only ¡§good¡¨ image quality for Contax. It may be the factors of smaller aperture, CCD type, noise reduction ability and exposure control, etc that deteriorate Contax¡¦s final image quality.

My additional reasons to give up Contax are as follows: -

I use Contax C/Y prime lenses for travel purpose. I also have a TVSIII. Optical quality for a TVSIII zoom is not comparable to C/Y prime lenses. At 8x12 enlargement, the difference is substantial. I would expect that TVSD would be more or less at the grade of TVSIII. My required enlargement for digital picture is 4R to 5R and I would avoid 8x12. For a compact zoom lens selection, the minor difference (if exists) between the optical quality from TVSD vs Sony DSC-V1 because of the lack of T* coating is tolerable if this could save me about US$170.

At 2594 x 1944 pixel (Sony) or 2560 x 1920 (Contax), when converting to 24x 36mm film scale, it would mean about 70 pixel per mm. The equivalent theoretical maximum resolution is limited to about 35 line per mm. You can¡¦t expect magic result from either brand.

Aperture value is quite an important factor for me for low lighting and indoor shooting without flash where Sony could have f3.2 at 2X, f3.5 at 3X and f4 at 4X which is about 1 stop faster than TVSD. It means that you could have an equivalent gain from ISO200 to ISO100 in indoor condition to reduce picture noise.

My Aria uses Metz 32 Z-2. Sony could use external flash which could accept my Metz 32 Z-2 on its non-TTL tele-computer apertures mode for distance group photos at f4 or f8 at ISO100.

Additional advantages from Sony include 2:3 frame format select which is convenience for me for photo processing, full manual control, higher LCD pixels, TIFF format storage, exclusive hologram AF in dark, 640x480 mega movie ability.
 
Hi guys,

I have just posted some images taken by the TVSD on the web for your review. Personally I like the B&W and Sepia effects a lot, and these out of camera effects are superior, IMHO, to FM's Digital_BW_Pro action used at Photoshop. One inherent drawback though, with the TVSD and many other P&S's, is the ultra wide angle lens that results in less than satisfactory bokeh even at 35mm f/2.8.

I will try take more pictures in the near future at various ISO's to illustrate the noise level as well.

Here's the site where I have uploaded the images: www.pbase.com/tvsd

Enjoy.

Nice stuff Ken. I won't bother trying to evaluate the photos technically, I'm just looking from an artistic point of view and I like them. That image of the white phalaenopsis with the beautiful view through the window just has me captured. It keeps making me think of a Nero Wolfe novel!

Really lovely that one. Nice framing. Sets a mood. By the way, is it possible on the TVS-D to do exposure corrections? I was thinking a half stop to get the whites to pop would have been nice, while not killing the outside view through the window. And my curiosity is killing me, but where is this view, it is stunning. Thanks, Lynn
 
Hi Lynn,

Thanks for your compliments. To answer your question, the TVSD does allow exposure compensation. Unfortunately without any RAW format, there are certain limitations on post editing. I do agree with your suggestion that adding a 1/2 stop would be more pleasing. I was just too lazy to bracket at the time. This picture was taken in my home in HK. Luckily I can always go back to the same scene and retake with better exposure.

Today I took some more pictures with the TVSD and S50 today. Once they are processed I will post them onto my link.

Ken,
thanks for posting the B&W. I have been wondering about how good the the TVSD is in B&W. Very nice sharp pictures. Are the out door ones on tripod too? I am using the S50 as my P&S and now in the process of buying the TVSD. Your comparison will be of most interest. Can you please please elaborate on what you meant regarding the 35mm end as less than satisfactory? Thanks.
 
James,

I like the b&w ones very much as well. The sepia in my opinion are also very nice. When I said I was not satisfied with the 35mm end, what I really meant was that the bokeh effect was not dramatic enough due to the ultra wide-angle lens used for P&S's. I like composing pictures with sharp foreground subjects with nice bokeh background. Unfortunately this is not quite feasbile with the TVSD lens. I hope this is clear.

The outdoor pictures were not taken on a tripod. I was playing a round of golf and had my camera around to kill time while waiting. They were not meant to be perfect, but they certainly illustrate the quality of TVSD images shot under normal conditions.

I have now added a comparison of TVSD vs. S50 images shot at different ISO's in my link. There is also a macro comparison on both along with my beloved 10D. Let me know what you think after seeing the results.
 
Ken,

All of these photos are interesting - and many are quite enjoyable.

It's hard to know about cameras, isn't it - and the TVSD appears to be one with particular personality.

I know it would be useful and interesting to me at least to see some more comparisons with the S50 - both for indoor and outdoor available light scenes.

If it suits your purposes and convenience also, then nice to see.

Regards,
Clive
 
Simon, yes it is indeed a Lange Tourbillon. Very beautiful watch. Have had it for almost two years and still haven't worn it once yet.

Clive, I like the TVSD very much, except for its lack of RAW capabilities. I would love to take more available light scenes to illustrate the difference between it and the S50, but unfortunately the S50 belongs to a friend of mine, and I would have to borrow it from him again to make any further test comparisons. I promise when the opportunity arises, more pictures would be uploaded. Will keep you posted.

Ken
