Hiee Dennis...
I have to thank Ratboy for "loaning" his RD175 and i had a real hands on trial of the shots taken and to my surprise...

The MRW(minolta raw) files from this cam could also be opened by the dimage viewer - very surprising.

I compared the shot "cleaniness" with the A1 out put and the images taken from the RD175 is an obvious winner. Its 3 CCD gives images better than the A1 bayer pattern imager.

I was soo happy with the images taken with the RD175 that i even gave Ratboy a stack of pictures taken with it to convince him that thae RD175....though large and bulky is good ......if you know how to appreciate it.

Its white balance is good too.

No frills camera.

Wow, I think you are kidding?

First, the RD-175 doesn't produce MRW, it produces a different format called MDC.

Second, the RD-175 also uses a Bayer pattern -- it's not three 1.75 Mp sensors, it's three 768x494 pixel sensor (VCR sensors really!). The sensors are then stitched together. One sensor senses R/B, two senses green, and in practice they act as one 1.75 Mp Bayer pattern sensor.

Third, any modern camera will beat the RD-175 on most accounts. An A1 will blow it out of the water for sure! I am from time to time shooting an Olympus C-5050, and while an irritating camera to use, the images produced by it are so much better than those from the RD-175. No contest.

What is 3CCD? I saw it advertised for a Panasoic videocam as well....

3CCD, in the common usage, is the act of using one CCD per color channel (red, green and blue) instead of using just one (with a Bayer pattern filter). Thus every pixel in the final image is constructed of RGB directly from the scene and no interpolation is required. This leads to higher quality. Unfortunately, the system used in the RD-175 is nothing like that; "3CCD" is printed on it to give some credibility, and it has three CCDs, it's just that they don't give higher quality -- the usage of three CCD chips was for cost cutting reasons only, as they could use inexpensive mass produced video camera CCD chips instead of larger and more expensive "real" chips. The RD-175 is a Bayer pattern camera, and "3CCD" is unfortunately only marketing speak in this case.

Hmm.... :think:

Sharks.....i am wrong .....Now then i remember that i used the RD175 download software(which was running off a diskette.... and it converts to JPG. Just when i thought it was a MRW files.

Sorry GUYZ!!!!!!! i am indeed wrong. I checked the CF card again and found from the EXIF data that its from the RD175.......and its the JPG not MRW!!!!!

Well...as far as the noise quality....its my personal taste though. The RD175 seem good in noise control even its at a fixed ISO.....

Well....on the humour side of it......i brought it out and fixed a 70-200 on it and the park cleaner thought i was using a video camera!!!!!!!!! :bsmilie: :bsmilie: :bsmilie:

Thnx Magnus...

rgds,

Hi Magnus

Thanks for the reply

Here's another advantage of the RD175 over most other
production digi cams to date...

You get free arm muscle workout : )
No need to pay for gym membership
( unless you want to workout the lower half body ).....
