Likaleica Posted October 14, 2007 Share #1 Â Posted October 14, 2007 Advertisement (gone after registration) I'm sure this has been discussed ad nauseum in this forum, but I haven't been able to locate it. I have some older R lenses that I would now like to convert to ROM. For those who have done it, does it take a long time for NJ to get it done? and are they essentially identical to factory ROM lenses? Also, cost?

psquared Posted October 14, 2007 Share #2 Â Posted October 14, 2007 I had ROM installed on my 35 lux in NJ about 2 years ago. I believe the turnaround then was 2 - 3 weeks, and it cost around $200. I'm not too sure about the fee. However, the turnaround may be longer now because of a backlog of repair work in NJ. My R9 needed the photocell replaced about a year ago. The turnaround was about 2 weeks then. The photocell blew again, and this time, it took them 10 weeks! The ROM should be essentially same as the factory installed one.

rsolomon Posted October 14, 2007 Share #3 Â Posted October 14, 2007 i have it done to my lenes in NJ. and as mentioned the price around $200, this proce will not include a CLA of the lens just changing the mount to add the ROM contacts. Functionality is identical to orginal factory ROM. Â honestly im not sure why i did it - the ROM funtion at this point appears to be limited - but they are there. Â perhaps in the future they will play a larger role Link to post Share on other sites More sharing options...
sdai Posted October 14, 2007 Share #4 Â Posted October 14, 2007 Adding a ROM contact may be important for the wide angle lenses if Leica runs in camera correction and the lens could only benefit when it can be recognized. Link to post Share on other sites More sharing options...
EH21 Posted October 14, 2007 Share #5 Â Posted October 14, 2007 Actually if you are using the DMR, besides having more data in the EXIF you also get some automatic vignetting control. I believe this was shown to be true in the DMR bible thread on another forum. Link to post Share on other sites More sharing options...
robsteve Posted October 14, 2007 Share #6 Â Posted October 14, 2007 Adding a ROM contact may be important for the wide angle lenses if Leica runs in camera correction and the lens could only benefit when it can be recognized. Â Leica does run in camera correction. I was the one that posted a comparison of my 19mm ROM with and without ROM being utilized. The DMR not only corrected for vignette, but there was also a little cyan corners it corrected too. Â It is easy enough to try for yourself, just take a picture of something white, in my case a light table, then tape over the rom contacts on the lens and take the same picture. Â Here are the 19mm shots. The lens was shot wide open. The dirt you see in the images is just marks on the light table, not dust on the sensor. Can you guess which one had the in camera ROM corrections? Â Â Link to post Share on other sites More sharing options...
sdai Posted October 15, 2007 Share #7 Â Posted October 15, 2007 Advertisement (gone after registration) Thanks a lot for posting these samples, Rob. Â I first heard about this at a Hasselblad demo when a rep explained the correction they've done in the backs and said they've done the same in DMR's firmware but I had never had a chance to try it out myself because all my lenses stopped at 35mm and nothing gets wider ... Â This is pretty cool ... no wonder DxO never bothered to support any Leica camera. Link to post Share on other sites More sharing options...

Likaleica Posted October 15, 2007 Author Share #9 Â Posted October 15, 2007 Thanks, guys. Looks like I'll be without my lenses for a couple of months... Â If only I could hibernate during that time Link to post Share on other sites More sharing options...
rsolomon Posted October 15, 2007 Share #10 Â Posted October 15, 2007 Tim, not sure how many and which lenses you have but i rotated mine through the process ( 2 or 3 at a time). For me it worked out well since i was unwilling to give them all the lenses at one time - Link to post Share on other sites More sharing options...
robsteve Posted October 15, 2007 Share #11  Posted October 15, 2007 Thanks, guys. Looks like I'll be without my lenses for a couple of months... If only I could hibernate during that time  You should try the Canadian Leica service agent. They do the ROM conversions and have a lot of the ROM parts in stock.  They also have quick turnaround, in the range of a week or two, not months.  Swarovski Kahles Link to post Share on other sites More sharing options...
