Welcome to the Dyxum Lens Database. This is the index page that integrates all information about lenses that is maintained on dyxum.com. The scope of our database covers any piece of optic that can directly be attached to a A-mount camera. Before venturing into the database you are advised to read the Lens Glossary which will help you get a general idea by looking at a particular lens's picture, name and even model number. If you would like to contribute to the database by reviewing the lenses you have experience with, you must read and understand the Lens Database Reviewing Guideline to be able share the same common perspective with the other reviewers. Otherwise your review could be misinterpreted and do harm than good.
* Have a suggestion to improve this Page? you can tell it by replying to this topic. Edited by Micholand - 20 February 2019 at 17:44 |

i noticed that the leitax adapted Contax/Zeiss C/Y MM mount, Leica R, Zeiss ZF &ZF.2 and Voigtleander SL_II lenses are not mentioned. i am aware that to use them some reversible surgery is required to the original mount, so using them is somewhat more complicated then just putting a adapter between body and lens, but maybe they can be listed as "adaptable through mount conversion"?

I don't think so - their not native A-mount. Furthermore, this was asked before about the M42 lenses and it was decided not to include them.
I, for one, am against including other mount lenses. There are enough resources for these kind of lenses. Take a look at mflenses or the alternative gear forum on Fred Miranda. Hope this helps. |

i did not ask to list them as a-mount lenses but as lenses that may be used with a adapter.
that category already exists and at the moment m42, adaptall, t-mount and MD are already mentioned above. it thus would be merely a extension of the actual practice, not something completely new. |

Can we get a pointer to the Sigma/SLT issue onto this page? Seems like the "right" place for that info to be... |

Hi all ~
After reading some of these posts I have decided I am clearly over my head. :o) Hopefully someone can throw me a raft or at least point me in the correct direction. I have a nice basic Sony A230 and was given and old Minolta SRT MC ii manual focus camera with 4 different lenses. I was told that it may be possible to buy an adaptor. Could you super smart people please, in simple terms, tell me 1. where I could purchase such beast if it exists 2. how I tell if my lenses are compatible with my a230 with an adaptor 3. will this be finacially worth it 4. will I have to do anything different in taking pics once i am using with said adaptor and lens 5. have you rolled your eyes yet at my ignorance :) Thank you soooo much ! |

Hi Krystin,
First - a big welcome to Dyxum; and don't be worried about what seems like a simple question; we were all starters here once (and I started off using this database in my initial foray into the database so you are not alone!). Right - first thing is that the database is for the A-Mount lenses and no others - these are the Auto focus lenses as developed by Minolta and taken over by Sony for the A-series cameras such as you have. what you have been given is the forerunner to these cameras with the 'old' manual focus MC or MD Minolta or Minolta-Rokkor lenses. These can be made to work on your camera and this is usually via an adapter. These come in two forms; one is a straight adapter that fits between the body of the camera and your lens than fits on to it. Sometimes (always?) they have a glass element in them so you end up with a slight degradation of quality. the other is to have the mount replaced with a generic 'A' mount; this means you loose the old mount but the lens then goes straight on to your existing body. if it has a chip in it then the camera can 'read' the lens and whilst it will be a manual focus lens you will get a focus confirm light in the viewfinder if the subject is in focus. I would tend to go with this option as it gives the best optical quality ultimately. You can do this yourself though there are plenty of people on here that can help/do it for you. Quality ultimately comes down to which lenses you have, though all may have some merit. You might want to look at what they are and post their descriptions and get some feedback on worth versus cost; if you have a 50 or 58mm f/1.2 then it's worthless.... but I would happily take it off your hands for you seriously, some may just not be worth it; I had a 135/2.8 converted over here in the UK this year and it's a dream to use and the quality is lovely, so please get some reasoned feedback first. Will it change your shooting 'style'? well, if they are fixed focal length ('Prime') lenses and you are used to zooms then yes; it almost certainly will, but I found for the better. It makes you look at a scene with a different perspective and think about your image more. performance wise they should be better as well - I could talk about Bokeh and the like but this you will pick up as you use these and see what the results are like. Does this answer your questions? I hope so and if anyone else spots something I have wrong please correct it! Once again, welcome aboard and looking forward to seeing some images from you! Best regards, Neil. edit - typo! |

Another hugely useful Dyxum asset. Thanks to all who have contributed to it and continue to contribute. I use it frequently. I always consult this data base before purchasing any photographic lenses.

Hello, Kristyn; wecome to Dyxum!
Everyone starts somewhere, and nobody starts knowing it all; everyone here, even the most skilled & the most knowledgable, is here (at least in part) so they can learn!
1. Your older lenses are... well, let's call them "semi" adaptable. Adapters *DO* exist for Minolta manual-focus lenses to the Alpha-mount; but they (almost) always cut -- at least a bit -- into the image quality of the lenses. And, of course, they remain Manual-Focus lenses; the old MF bodies are notablly superior for focussing with these, because of their bright pentaprism viewfinders and their focus-screens. One good vendor is James Lao. (Answer 1.5) - One other option, if you happen to have any really nice lenses, is to get the lensmount replaced: have a technician remove the old lensmount, aned install a new one. This is expensive, but sometimes worth it; of course, then you cannot use these lenses with the old SRT you have. This is a bit of a custom job -- not something the "average repair shop" will do! -- but several of the folks here on Dyxum might be able to do it, or point you to someone who can. 2. The reason a lens isn't "compatible" (or is only "semi" compatible) is when -- as is the case with the old Minolta MF mount vs. the A-mount -- the distance from lensmount to the focal plane (where the sensor (or the film) sits) is too short. When the lens is made for a longer focal distance, the adapter just becomes a tube -- of variying length -- with a lens-mount at each end. But when the lens is made for a mount that needs a shorter distance (and the adapter itself always adds at least a bit of distance!), the adapter needs glass (to shorten the focus); those extra bits of glass are what degrade the image. If such a too-short-focussing lens is used with a glass-free adapter, the lens can no longer focus all the way to infinity; in the case of Minolta-MF to Alpha, the glassless adpaters cannot focus beyond -- I believe -- about 3ish feet away (at best; some may not even focus that far!) Glass-free tubes like this -- not adapters, just tubes with the same lensmount at each end -- are sometimes used for close-focus work, loosing infinity focus but gaining close-up ability. In this context, they're called "exentsion tubes." Note that glass-less adapters don't degrade image-quality, just ability-to-focus 3. Whether it will be "financially worth it" depends on your lenses (and your willingness to deal with manual focus, etc. -- try using them on the SRT with film, see how you like it). If you'll tell us what each lens says around the front, we can probably help you figure out if any are worth adapting. One other advantage to you -- and again, "worth it" is a relative term -- is that you get a "feel" for different focal lengths without having to buy them. If you discover that you LOVE taking ultra-wide shots (presuming an ultra-wide is one of your old lenses) but don't like "the whole MF thang," then you know you will want to buy an ultrawide for your a230. 4. Well, the lenses are manual lenses -- you'll need to focus yourself, and probably also set your exposure manually. This can be a good thing, however -- quite a few people feel that the only way to learn good photographic skills is to spend some time doing everything manually! 5. No eye-rolling here. As I said above: nobody knows it all, ever. And everyone was a "beginner" at one point or another. My experience is that those most-prone to "eye-rolling syndrome" are those who are most-recently ignorant themselves... ;-) - Steve S. |

Some Sigma lenses have firmware/compatibility issues with the SLT line, but Sigma generally fixes those, except for the very oldest models of lens. It *APPEARS* that the 18-200 doesn't suffer this issue... see here (I presume this is the lens you mean?) and here. Nevertheless, I'd have expected this lens to (potentially) suffer this issue... - Steve S. |
