not mine, of course, but it's interesting to note that Minolta put a lot of time and effort into the Vectis line.

interesting and (according to some) one of the reasons for their ultimate demise - i wouldn't mind owning the 400 reflex, if only there was an adapter for alpha mount!

Ahoy there!

I appreciate this is an old thread but I've come across this lens on the jungle website and not having heard of it before I've tried to research it but with little success hence posting here.

If anyone knows this lens in greater detail,could you please offer your insight about it in terms of it as a lens (I know the MIN500F80 + Sony versions) but not this one. For example, what mount is it as the image I've seen has contacts so is it A-Mount or is an adapter required,and if so,does one exist and if it does, what make/model is it?

Hopefully the 'wise one's' on Dyxum will have the answers.

Tally ho!

Vectis lenses have the V-mount. They are APS-C lenses and do not fit A mount cameras. AFAIK there is no V-mount to E-mount adapter.

This is the Wikipedia page on Vectis SLR's for some background information.

There is one, reviewed right here. And talked about earlier right here. I see you actually commented on it at the time.

You're welcome! ;)

Don't bother buying it .

I have several copies of this lens as well as the A-mount 500mm f/8 reflex and it gives very good images .
However it fits only 2 APS film SLR cameras and the 2.75 megapixel Minolta DiMage RD3000 from nearly 20 years ago .

As linked to , there is one adapter that exists to fit it to the Sony E mount cameras , and only 7 were ever made .
I have one , as can be seen in the linked to Dyxum Review .

Prices vary widely , from £15 to £100 , until they realise you can't even manual focus the lens without power supplied to the motor . Then they probably stick it back on ebay again and make a loss !

And now for a few sample images

Since the Vectis lenses park at infinity, I was wondering if there was room if someone used a helicoil in the adapter - then I saw that @darosa has done this before . No aperture control (which would not be needed on the 400), and probably only a short focus range, but it apparently is another way to adapt one.

Don't forget were talking about the 400mm Reflex here .
It doesn't have a hard stop at infinity , it focuses beyond it .
Depending on temperature , the infinity focus point can move about a bit in use . On a very hot day , the infinity point is different from on a very cold day .

When you turn off a Vectis mount camera it turns the focus point indicated on the lens about 1/4" past the infinity mark .
When the 400mm Reflex is mounted on an E-mount body with the Monster adapter the focus point is rotated about 3/4" in the focus distance window on the lens .
So it could end up rested at 10m , 50m or somewhere beyond infinity .

You could still make an adapter with a helecoil , but you would need to use one short enough to reduce the registration distance to allow for this .
The lens is internal focus , so how moving the whole lens would effect image quality , I don't know .

Regardless , you still can't mount it on an A-mount camera , as per Marks inquiry .

Anyone after Reflex lens should be looking at the auto focus Sony / Minolta 500mm f/8 Reflex or the manual focus Tamron adaptall 350mm f/5.6 or 500mm f/8 Reflexes , all of which are very good lenses .

Thanks for the detail, Neil. I was being entirely hypothetical, already have a couple of mirror lenses. Reading through the threads, there are nearly enough clues for someone to make another "Monster" adapter - control of aperture apparently uses the same protocols as E mount (one would have to establish which Vectis contacts do this), and one would also need to establish which Vectis contacts power the focus. Sacrifice a Vectis body for the lens mount, design and 3 D print the rest of the 38mm register adapter, wire it up, and you would have it. For the 400, would only have to power the focus motor, since there is no aperture control needed. Hypothetically.

Years ago I started dismantling some Vectis lenses and bodies to work out how to make an adapter to give basic controls .
I worked out what some of the contacts were linked too , and how I could make some controls with separate switches .
Never got any further and then this adapter came up . End off efforts !

The monster adapter identifies itself as the E-mount CZ 24-70mm lens , but offers powered manual focus only .
Aperture works like a native lens , so that must have been easy to archive .
Only power is supplied to the lens for manual focus , with lenses with the AF/MF button .
Strangely , when the camera is turned off , the focus motor does operate the focus motor the same as on a Vectis body and turns the lenses back to the infinity point ( or there about's) .
So it seems that auto-focus could be achievable .
This wasn't a priority for the maker , but if you were to make one with salvaged parts from an 18-55mm lens or something , someone with the abilities could make one that is fully functional .

The shortest long tele lens I've come across is the Super Paragon 300mm f5.6 T-mount mirror lens. Only MF, but it works well with a dumb adapter of a speed booster. I assume it could work with a motorised helical adapter if there was one.
Miranda F & Sensorex, Sony A58, Nex-6, Dynax 4, 5, 60, 500si/600si/700si/800si, various Sony & Minolta lenses, several Tamrons, lots of MF primes and *far* too many old film cameras . . .

There is a mortised adapter , for suitable models with a further suitable adapter .

Techart
LM-EA7 Leica M to Sony E A/F adapter
, as long as the lens isn't too heavy , and with longer F/L lenses a bit of pre-focus is required .

I've seen everything now !
One of these has just sold on ebay for £206 !!!!   
Minolta Vectis 400mm Reflex sold listing

Four times the maximum going rate .
Looks like a few people were bidding on it , presumably they thought it is compatible with either an A-mount camera or got it for an E-mount camera with the LA-EA3/4 adapters .

I think someone will have bad buyers remorse in a few days time !

I bought a new in box Minolta 500mm f/8 Reflex a few weeks ago for just £175 , just shows you should shop around and wait if needed , but most importantly , know what your buying !

I hope no one on here got it .....
