E-Mount (NEX) adapters

Yes, but be sure that is your mount.

Will the MD - NEX adaptor from first page work on FF a7RII camera?

Why I ask is that the Potodoix has one Minolta MD-E that them self says is not for FF and points to the Potodoix Pro version?

I've got several of the cheap MD-NEX adapters and they all work fine with full frame (A7RII). Some have a little chrome on the back of the inside front mount that needs blackening, but other than that, no problems. Is there a particular MD lens you want me to try out with the A7RII? Pete

Hi Pete,

Nae, I just looking for what one to buy, mostly to test my non special Minolta MD lenses I once bought to do reverse macro with.
Would be nice to know if any of them could actually work ok on the a7RII.

These I own:
Minolta MD
50/1.4
35/1.8
28/2.8
20/2.8

Cheers.

Edit: I meant optically ofc...

To my knowledge, any of the MD to E-Mount adapters will work for manual focus and aperture. Here in the states, I use Rainbowimaging. They are also in ebar along with many other Chinese made adapter suppliers.

I bought a clean, used NEX 7 a few years ago, and the very first thing I did once it arrived was to order six different adapters for it. I bought "FOTGA" adapters from an eBay seller.

One of the main reasons why I bought a NEX was so that I could mount my Canon FD lenses on a digital camera without having to use an adapter with a corrective glass element. Prior to buying the NEX, the only digital I had was a Canon DSLR, which can't infinity focus FD lenses without the use of an adapter with corrective element.

The adapters I bought were Canon FD, Nikon F, Pentax K, M42, M39, and C-mount. Since then, I've bought adapters for Minolta MC/MD and adapters for Canon FD and Nikon F that have the built-in tripod mount, a very nice feature.

I have used all of the above adapters on my NEX 7 with no problems at all. Each provides a snug fit between lens and adapter and adapter and NEX 7. To my knowledge, these adapters will work on any E-mount camera, whether APS-C or FF.

I have a fairly sizeable collection of manual focus lenses, mostly Canon, Nikon, and Tamron. I also own a few M42, Pentax K, Minolta MC and MD, and LTM (M39) lenses. Ironically, I suppose, the only native E-mount lens I own is the 18-55mm kit lens that came with the camera.

Hey, Woodrim! Good to see you here!

Very interesting. Is this type of adapter available in other mounts also? If it has a good amount of extension, it can be useful as an adjustable extension tube to, say, get your 1:2 macro lens down closer to 1:1.

K&F Concept adapter, compared with unbranded ebay version

K&F

I first came across K&F concept at the 2018 Photography Show in Birmingham They offer some products that will look very familiar to anyone who shops for e-mount adapters on ebay, but the fit and finish of their products does seem to be quite good.

They offer up to three variants on each lens mount – one basic (£17.01), one ‘Copper’ (£19.23) and one with a tripod mount built in (also £19.23).

Their website (https://www.kentfaith.com/sone-nex-e-mount-adapter) offers prices in various currencies, so you should be able to get an up-to-date price for your region.

I tried to find out what the differences between the basic and copper models was and failed to get a reply – so I ended up getting one ‘Copper’ Minolta SR adapter (mis-described as usual as ‘MD-NEX’) and another standard quality one for Nikon AI (for lenses with an aperture ring – they also do a version for Nikon G lenses that had a ring to control the aperture on the adapter). I’ve not tried out the Nikon adapter yet (it is for a possible future purchase), so will not be reviewing quite yet, other than to compare the standard and ‘copper’ versions.



Standard quality is pretty good – the tube used for the adapters is of substantial thickness, the bayonet catch is of decent quality and size and there is not much to complain about in finish. For the standard version the e-bayonet is of black anodised aluminium and is a good fit for a metal a7 bayonet. The ‘Copper’ quality adapter is much the same, but rather than the bayonet being spun out of the same aluminium as the body of the adapter, the Copper has a separate metal bayonet screwed into the adapter body – (I’m presuming that this is of chromed brass). The push button on the SR adapter is nice and broad and weight is about 15-20 grammes more than my old MD-NEX adapter.



The SR bayonet on the front is only held on by three screws (similar to the old adapter), but the whole bayonet seems very secure.

As the Copper version is only just over £2 more than the basic one, you might like to go for that version if you are going to use the adapter a lot – but there is absolutely nothing wrong with the quality of the standard K&F version. The version with a tripod mount (where available) is the same price as the ‘Copper’, so I figure it is probably based on the normal quality adapter.

K&F Concept offer a 10% discount if you buy two adapters at once and offer a 30 day return. The adapters themselves turn up in quite neat little plastic boxes.

On the whole, if you want a reliable adapter of good quality K&F Concept adapters look to be a good bet.
