When I got Photoshop CC 2017 I presumed there would be a ton of Minolta lens profiles, what with being around for decades and the A mount having been adopted by Sony. Nope, CC 2017 came with with a paltry few, none of which were AF! No Maxxums.




Mildy irritated, I downloaded the Lens Profile Downloader.

Is this some kind of joke? There are NO MINOLTA lenses on there. Minolta wasn't even listed! So I looked under Sony. Still, not a single Minolta A mount (And Sony just announced another A mount camera).

Adobe understands that Sony bought Minolta's imaging division and the Alpha is based on Minolta, right?

Hi.

Most of these older Minolta lenses preceded the lens corrections feature in Camera Raw and Lightroom, and many were out of production (supplanted by Sony-branded equivalents) at the time the feature was released.  Several of the Maxxum lenses share the same optical formulas as the Sony Alpha lenses with the same specifications and can be used with the older Minolta-branded models. You can apply them and set a new Lens Profile Default so Lightroom will automatically recognize them in future imports. 

The Minolta MD film SLR lenses in the screen shot above were generated in house from a personal collection of one of our teammates (me). 

Regards,

- Chris

If not for you, it looks like Adobe ACR would not have any Minolta support at all!

Minolta MC and MD are even older, and, not even supported by Sony.
The Alpha originated with Minolta, and the "A" in A mount was actually short for Alpha. (Sony later muddied things by adding the E mount some time after they acquired Minolta's imaging division).

The Minolta A Mount lenses are natively supported to this day on Sony bodies (as seen on the new Alpha99-II) or via Sony's LA-EAx adapters (2 and 4 support AF) on E mount bodies (both APS-C and Full Frame).

There is an active economy in Minolta A mount lenses via Ebay, Facebook, Amazon, etc., precisely because they are very popular with Sony users. I am sure Adobe can afford some used Ebay A Mount lenses. Heck, get the Tamron or Sigma A mounts for that matter- they are also popular with Sony users (the price is so right!).


> "Several of the Maxxum lenses share the same optical formulas as the Sony Alpha lenses"

I admit to skepticism. Can Adobe post citations? And if true (I have read that even the early knockoffs by Sony had minor changes from Minolta designs), Adobe needs to let us know exactly which Sony branded lenses are clones of which Minolta lenses. Can you arrange this verification?

Also, a lot of us E & FE body users are using the Sony LA-EA2 or LA-EA4 adapters (supports Minolta and Sony A Mount AF lenses, as well as other brands). Obviously we lose about half a stop worth of light with these adapters. But there's the hairer question of whether or not these profiles would be accurate.

That is, we have the variable of sensor size; would an A Mount lens profile created on A6000 with a LA-EA2 create a valid profile for, say, use on a Alpha99II? Or the other way around?

The adapter also adds distance between lens and sensor. How might this affect efficacy of A Mount lens profiles (either in generating profiles or in using them)?

Unfortunately we don't have the resources to locate and profile all the Minolta versions of the Alpha lens line. It would be ideal if we did, but the reality is, we don't. This is one of the drivers behind providing the free Adobe Lens Profile Creator. Customers who have these lenses can use this tool to generate, and share if they like, profiles for the Maxxum or any older line of lenses.

The adapters you mention would mainly affect the vignette corrections between an SLR type body and a mirrorless, but only slightly in my experience. Any variance can usually be resolved by adjusting the Vignette slider on the Lens Corrections tab. You can set a Lens Profile Default to set this adjustment for all future camera/lens combinations that match the profile being applied.

The other issue with the adapters the lens metadata written to the raw files. Sometimes it is different than the metadata written when a lens is attached to its native mount (i.e. without the adapter). Since this metadata is used by the profile matching logic, automatic matching may not work. This is where setting Lens Profile Defaults can help provide a hint to matching logic.

Terry,
Ideally, you should create your own profiles with your camera and lenses with the profile creator  software. Then any sample variations would match your lenses.  Of course this is very time consuming and you have to follow the instructions exactly
I've not done this myself, I have downloaded profiles for Minolta lenses using the down loader software. These have been provided by users who have created their own profiles.  They work well enough for me. I'm mainly interested in distortion corrections. An example of a profile that I use a lot is one for the Minolta 70-210mm f4.  
I love my Minolta AF and Minolta MF (Rokkor) lenses, but sadly I'm not confident in a bright future for the Alpha system. Though Sony has just introduced the A99II, an excellent, camera, when was the last time they introduced any new lenses?  If Sony is only offering token support for the system, I personally don't expect much attention from 3rd party companies (Adobe). For example, Sigma is not longer offering new lenses in Alpha mount.  Tamron is, but but not until they've made significant profit form other mounts, i.e. Canon and Nikon.
The FE mount cameras and lenses are what are selling and Sony needs to go with what sells (if they want to stay in business). As unhappy as it may make many of us. We can complain all we like, but the only thing we can really do to help is get out there and buy Alpha mount product and hope that many others do as well!

I have some 150,000 images taken with an A100, A700, and A850. Unfortunately, my entire Sony system was stolen a few years ago. The insurance money bought me new Canon gear which is fantastic, but I have no way to generate lens profiles as i no longer have the lenses.

I mostly used a Minolta 50mm f/1.7, Minolta 70-200 f/4 beercan, and Minolta 28-135 f/4-4.5. All of those were and are popular and good-quality lenses.

Bottom line is that I have no way to correct any of my old RAW files. :sigh:
