    I originally posted this on DPReview in 2015 after I persuaded the maker of this adapter to do a small production run .
    Manual focus only , but allowed you to use the Minolta Vectis lenses on Sony E mount cameras .
    Not all lenses were useable as some don't allow manual focus .
    They have since set up business making an assortment of adapters , the last one being released via a croudfunding site in the way of an autofocus Minolta V to Sony E adapter .
    More of that later .

    So here is a copy of my original review ;

    Minolta Vectis V to Sony E Monster adapter Review .
    Nov 22, 2015

    23105521026_16800095db_c.jpg

    I've had the Minolta Vectis APS film SLR system for a number of years , Both the S1 and S100 film and V-mount DiMage RD-3000 DSLR from 1999 .
    The film cameras are a nice lightweight rain proof system , which is why I bought it . I have been using them for over ten years alongside my A-mount film and digital cameras .
    The system was released in 1996 and was a bit like the Minolta film equivalent to Sony's E-mount digital alternative to A-mount .
    I think David Kilpatrik on Photoclubalpha was the first to try and utilise these lenses on a digital camera with more than 3 megapixels (!) though it involved duck tape.

    .
    I've started dismantling some of my spare Vectis lenses to see about providing power to them to make use , but hadn't got very far when this thread popped up .
    Intrigued , I contacted the maker and three months later it arrived .

    First of all , this adapter powers up the lens so that lenses that allow manual focus can be focussed manually .
    two of the Vectis lenses don't allow this so cannot be used .
    This adapter does not support auto focus .

    The adapter enables aperture control the same as if a native E-mount lens is fitted , ie , via the cameras control wheel .
    All exposure modes work as normal , P,A,S,M . Auto ISO works as intended .
    The adapter reports the focal length to the camera , not 100% accurate as the 400mm reflex is reported as 405mm , The 50mm Macro reports 51mm and the 17mm is reported as 18mm .
    Likewise the 22-80mm zoom is reported as 21mm .
    Whether this is a quirk of the adapter or the true focal length of the lens , I don't know . This makes no difference in use , if your camera has image stabilisation , it will work automatically ,as normal . a mm or two out wont cause a problem.
    Because the camera knows the focal length of the lens in use / set to in the case of a zoom , in A mode , with auto ISO , it will select a shutter speed and ISO to reduce camera shake as normal , the same as any A or E mount camera .

    Like the Canon EOS lens to Sony E-mount adapter , there are a few minor issues to take into mind .For normal everyday use this adapter is perfect for my needs , doing everything I want it to do ( A/F would have been nice though !) .
    Build quality is very good . This hasn't just been knocked up in someone's shed , it is very professionally made .
    The maker had only had another six made , hopefully he will have more made as these will sell quickly .
    A couple of people have contacted me via Dyxum and another via Flickr .
    So , just a few things to be aware of ;

    1;this adapter is not compatible with the original NEX 3 or 5 .
    All later cameras seem to be supported .

    2;On some cameras , if it is set to continuous advance , or a rapid succession of single shots are taken , the camera / adapter can freeze . This might only be an issue on higher end cameras .
    On my NEX 7 and John's a7 this happened after between 5 and 8 shots . On an a3000 and an NEX 3n , you could shoot without any problem until the cameras buffer was full .
    This made no difference whether the camera was set to JPEG or RAW .
    In normal use this does not effect me (YMMV).

    3;on the NEX 7 , if the onboard flash is raised , when a shot is taken on about 3 out of 5 shots the camera would freeze .
    When using the HVL-F20AM flash unit , it improved to only 1 out of 10 shots would result in the camera freezing .

    With the a3000 , there was no issues with using either on board flash or a separate unit .

    As John does not have a separate flash , he is unable to test on the a7 .

    So between us , these are the only three issues found .
    Non of these issues are a concern to me , as it enables me to use my lenses in a way that meets my needs .
    Although the adapter was expensive , having the full range of lenses has made it worth while .

    The Lenses ?

    I'm very pleased with the Vectis lenses , almost all my A-mount lenses are Minolta , from a 16mm fisheye to a 300mm f/4 plus a load of zooms , plus Minolta SR lenses .
    So I'm well aware of the quality of Minolta lenses .
    I've used the Vectis lenses on the S1 and RD-3000 for years too , and have always been happy , though never enlarged too much . APS film had it's limitations due to size , but I used the cameras in the rain without a second thought .
    Minolta put quite a bit of effort into making these lenses to resolve to quite high degree to make up for that .
    So it stands to reason if the lenses for the larger 35mm film are good for APS-C , the APS-H lenses are quite at home .
    I have to admit that I was a bit concerned that they might not be up to it , considering how much I paid for the adapter.
    I have multiple examples of all the lenses so I will need to find which are the best ones , I've found out of my two 17mm ones , one could not reach infinity focus , but the other went beyond it , as per design .
    I think the other needs a shim taking out , surprised I never picked up on this before though . That's what magnified live view , focus peaking , 24 megapixel , and pixel peeping on a big screen does though !
    I need to compare my other lenses now though .
    On my holiday where I used them as my main kit I tested them out in normal use , rather than test charts and brick walls , I will be interested to try them on a full frame E-mount with A/S .
    I found the best camera to use the 400mm reflex on was the a3000 due to the ergonomics , despite the poor EVF , the majority of the shooting was with the NEX 7 .
    After using the EVF on the a77ii for a while , I found the NEX 7 a bit more awkward , for focus peaking , if you are focusing from near to away , it was fairly reliable .
    If focusing from infinity towards you , quite severe back focus occurred , still more testing is needed to work out how best to use it.

    The following links are to the sample pictures on my Flickr site .
    I will be putting reviews of the Vectis lenses on the adapted lenses forum when time allows .
    In the meantime , all samples have been set up in separate albums for each lens . I have multiple copies of each lens , so still need to test them to use the best .
    All shots are from normal use , no test charts or brick walls !
    I might be more critical on the final selection .

    Late last year after seven years , they announced they were making an auto focus version of the adapter and selling via a crowdfunding site , for a lot less than I paid for my MF version .
    Needless to say I snapped it up , a couple of days after it closed , the adapter arrived . much earlier than expected .
    Now available from here ; www.monsteradapter.com/collections/all

    The new one adds compatibility with two more lenses , AF only , as they don't have MF buttons or focus rings .
    Minolta Vectis 28-56mm F4-5.6 and
    Minolta Vectis 25-150mm F4.5-6.3

    For the adapter to function correctly the camera needs on sensor PDAF , not just CDAF like my NEX 7 .
    I'd already bought a Sony a7Riv which has this but bought a used a6600 to give me an upgrade with both this adapter and the LA-EA5 so I can use all my Minolta lenses on them too .
    Initaally I had problems with it functioning until I found you needed to "initialise " it .

    Here's a copy of the pots from the DPR thread ;

    Mine arrived on the 19th , but I'm having a couple if problems with some lenses .

    The 400mm reflex and 17mm sometimes lock up with the purple square "I can't focus" thing and the camera has to be switched off to reset .

    The 25-150mm , which I really want to work , doesn't .

    I've three copies of the 400mm to try and two of the 17mm plus a few more 25-150mm lenses , so it could just be there 25 year old lenses that haven't had much use .

    However, someone on Dyxum.com has also been having this problem and had the idea of setting the camera to "initialize" .

    And it seems to have improved it .

    Just got mine as well but weather has not cooperated to give it a good trial but AF works better on A7R4 than A6000.

    Try the "Settings -> Reset -> Initialize" that "Anthills" on Dyxum suggested .
    It made a massive difference with my adapter .

    The 25-150 was coming up f/90 when first mounted and camera switched on , AF first would move then just lock up with a purple square on both the a7Riv and a6600 .
    Since I've "initialised" it the aperture is correct , AF works a treat . Better on the a6600 than the a7Riv , but very satisfactory . In low light at 150mm ( max aperture is f/6.3 here ) it's slower to focus but gets there in the end .
    17mm is working fine most of the time , but I need to check it out more in good light .
    The 22-80mm , 28-56mm , 56-170mm and 80-240mm all work great . I'm pleasantly surprised with the their performance .

    The 50 mm macro lens was whizzing in AF missing everything , but I've put on one of my other copies and that one works great .

    Finally the 400mm Reflex .
    I have three copies .
    The one I've been using on the original Vectis to E-mount is just hunting .
    I've figured out why .
    The internal baffle on this one has no flocking and is causing a rainbow flare effect , almost as if the rear element of a lens has condensation on it .
    This seems to be effecting the AF as light is scattered .
    I hope to remedy this by sanding the glaze off it .
    (EDIT ; I've just swapped the baffle for the one out of the "macro" reflex , so should work fine tomorrow)

    My Second copy needed the front elements taking out for cleaning , which I did years ago , unfortunately when it was reassembled after putting the second lens in that has the secondary mirror on , you ten put the first element back in and as this was screwed in , it turned the second one as well .
    This lost infinity focus , in fact it turned it more into a macro lens , focussing no more than 15 feet away . Sharp , but not a lot of use !
    I thought I'd stripped it down again to redo it , but clearly not !
    A job for another day .

    My third copy needs cleaning up as there's signs of fungus under the front element or on the second one back .
    I'll count the turns as I take them out to reinsert both these and on the other correctly .
    I'll use a bit of thread lock on the inner one and allow it to set before putting in the outer element .

    Despite the fungus , AF works great and it seems a nice sharp lens .
