hmic10 Posted September 6, 2021 Share #1 Posted September 6, 2021 Advertisement (gone after registration) Just got my r8 with a Cron 50 2 v1; So what is the advantage of using ROM lenses? I dont have the digital back, so where is the data going Thanks Howard Link to post Share on other sites More sharing options...
Advertisement Posted September 6, 2021 Posted September 6, 2021 Hi hmic10, Take a look here New Leica R8 User, What is the advantage of getting ROM lenses. I'm sure you'll find what you were looking for!
AZN Posted September 7, 2021 Share #2 Posted September 7, 2021 A simple web search works wonders here. Eg. https://www.apotelyt.com/photo-camera/leica-r-mount Link to post Share on other sites More sharing options...
andrew01 Posted September 9, 2021 Share #3 Posted September 9, 2021 If you don’t have the digital back its not worth paying the premium for the ROM lenses in my opinion. They are the latest generation and I have read some people argue that the coatings are better, but most likely splitting hairs. Link to post Share on other sites More sharing options...
masjah Posted September 9, 2021 Share #4 Posted September 9, 2021 AZN's link to Doug Herr's (apotelyt.com) site sums up the position very well. You just need to make up your mind whether or not the advantages for you are worth the extra cost. I don't buy the bit about coatings, but the lenses nonetheless will likely be newer examples. The other advantages are worth it to me, particularly displaying the correct aperture on variable aperture zooms, and transmitting the correct aperture through a 2X ROM extender, as well as the tweaked metering for any individual sample of a lens. They will continue to command a premium, so the extra cost may well be a worthwhile investment. Also, now I have an SL2, with the correct Leica R to L adapter, automatically letting the camera know which lens is attached is a real bonus. I realise this is not relevant to you currently, but it could well be relevant in the future, and is another reason why the additional premium will continue to be relevant, and make a ROM lens more desirable should one wish to sell it on. 2 Link to post Share on other sites More sharing options...
Technician Posted September 10, 2021 Share #5 Posted September 10, 2021 masjah, thanks for elaborate reply. Giving the direct and elaborate answer is much more helpful than throwing links to the search engine at newcomers, who don't know the forum so good as older experienced users. For newcomer to Leica R8 as myself, your reply was really helpful. Currently, I have the camera without the lens. My 35-70 f/4 ROM is on the way, can't wait. 1 Link to post Share on other sites More sharing options...
davidmknoble Posted October 19, 2021 Share #6 Posted October 19, 2021 @hmic10 the ROM contacts also work with the R8 and R9 matrix metering. The R8/9 know the vignettions of the lens at each aperture and will adjust the metering accordingly. So, when wide open, your Summicron 50 has some darker edges and the R8 knows that how many stops that is and compensates. In addition, if you ever take the plunge to a digital system like the SL, the digital cameras know what lens you are adding. Note that only the R8 and R9 have this data. The R6.2 (assume the R7?) don’t know which lens is attached. The matrix metering is probably the best black and white metering I’ve seen. I love the ROM lenses (but also use them on an SL2).

solareslarrave Posted December 2, 2021 Share #7 Posted December 2, 2021 Advertisement (gone after registration) And here I was thinking that the ROM would do wonders with the SF-58 flash I got waaaay back in April of this year! In any case, I chose to get as many ROM lenses (only have three out of four, but don't regret it) because I imagined they'd communicate better with the camera when using flash. Thanks for the additional information! Link to post Share on other sites More sharing options...

Thanks for the additional information! They do help with flash, to the extent that with a zoom flash head, and the correct SCA adapter, the camera can tell the flash what focal length is being used. This particularly helps when using ROM zoom lenses. You can hear the flash head zooming as you zoom the lens. Link to post Share on other sites More sharing options...
solareslarrave Posted December 3, 2021 Share #9 Posted December 3, 2021 Indeed, John, that's what happens when I use my 35-70 and 28-70 with any of my R bodies. Shortly after posting my reply I read the text from the link and saw confirmed what I imagined... which is what you kindly explained above. BTW, I like using the SF-58 with my cameras. As far as flash lights go, it's really good. 1 Link to post Share on other sites More sharing options...
