Contax RX

This coupling lever is actuated by the extension on the MM lenses. It signals to the camera that it is an MM lens mounted. The older AE lenses will not stop down consistently in T or P modes, in my experience, causing overexposure. Both the AE and MM lenses signal the maximum aperture to the body, but not with this pin/lever.
 
I've had some negatives come out totally unexposed when in aperture mode the indicated shutter speed would be at maximum, although not indicating "over". I don't want to stop down so as to keep a minimum DOF, and would prefer not to use ND filters. Manual mode is my best option, but habit has me staying in AE mode. Is it a shutter problem when instead of exposing at or near 1/4000 (For the 159) that the shutter curtains both trip at the same time resulting in no exposure, or should they default to the highest shutteer speed? If this is common to all models that contax produced? I'm thinking of buying an RX.
Thanks, Joe W.
 
I contacted Contax in Japan trying to find out if they had any intentions of creating either a new digital camera that could use their manual lenses or an adapter to mount the manual lenses on their new digital N camera. Thought you'd like to see their response:
'First of all we appreciate that you use Contax RX and various Carl Zeiss MM lenses. To your inquiry, however, at the moment we do not have any plan to introduce a digital camera body for Carl Zeiss MM(Contax mount) lenses and also have no plan for a adapter to mount the MM lenses on N Digital body due to the different diameter of the two mount and various restrictions."
 
An answer to J. Wojtaszekk's post about the unique Electronic focus with DoF indication.


The "new" RX-2 is a big step backwards, and I see no feature now which makes it superior to the Aria. I got my "original" RX precisely for the "unique" focus-electronic which now has been removed. This wonderful electronic is actually a measurement circuit for the <circle-of-confusion> which determins Depth-of-Field. (Someone on the PopPhoto forum mentioned that Kyocera had dificulty getting the chip manufactured, and that sounds likely, because it must be a complex analog circuit, which is very costly. I know, I am an EE.)
Here is the little paper I wrote on how to use the "Secret of the RX".

Hi Harry!

I really see nevertheless some differences to the Aria. The real problem might be that the new RX2 will not be available in Europe, because the price would be higher than of the old RX AFAIK. I love my RX but the focus assistent seems to me worthless.

This is indeed true , Kyocera actually announced the fact that they could no longer get the parts to manufacture the DFI....... Steve
 
Hello everyone,

I am thinking about buying Aria or RX. Can you help me with one advice? I tried Aria, but have not seen RX yet.

After pressing of the shutter release, Aria has short high pitch (motor/s?) noise - may be mirror and aperture electronic& motor operating - before the shutter noise comes with short delay.

Has the RX the same noise first and the same short shutter delay after pressing the shutter release? If not, where is the difference in this point between Aria and RX?

Has Aria motor operated mirror as RX and what is louder in Aria as in RX - the shutter or the mirror?

I posted this message also in the Aria review

Thank you in advance.
 
Hi Valentin,
I use the RX and the response from the shutter is for all intents and purposes instant. The shutter and the mirror are very quiet indeed (for an SLR). The mirror being slightly louder and of a higher pitch in sound than the mirror. I was doubtful about how quiet it would be before I bought it but I am more than pleased.
 
Can an RX with a damaged flash mount be repaired? Would it be expensive? (US$100? $300+ ?) I've seen one for sale with this problem that is otherwise sound. Any ideas would be welcome so I can figure out a fair purchase price for the camera itself.

Thank you,
Lynn L.
 
Hi Valentin,

I cannot say if the delay is shorter or longer than the Aria as I have not tried the two together. I have tried an RTS (1) and I think that the delay is about the same, that is negligable. It is not a problem in practise, the problem lies with our reaction times!!
