Minolta A 70-210 f4, 35-70 f4 on Sony alpha
11 months ago

I was just donated an old Minolta film camera, with the mentioned lenses included. I am planning to purchase an A7 full frame camera. I probably need to buy an adaptor because the A7 has the E mount and you need to use an adaptor to fit Minolta lenses on NEX cameras, not?

Anyone know how these lenses perform on modern Sony dSLRs?

Thanks

Sony Alpha 7

These lenses are quite popular among Sony users and will perform well on NEX as well. I just got the 70-210/4 "Beercan" to replace a similar Minolta 3.5-4.5 I had, and a friend of mine still likes his 35-70/4 over any other modern standard zoom. Get the LA-EA4 (which I have) and AF works (but is not blazing fast, unlike with my HSM lenses).

The Minolta 70-210mm f/4 is a very popular lens among a-mount shooters. Here's a little more info on your lenses.

Are there any other good adaptors (eg third party) that allow the conversion to E mount?

The LE-EA4 has been described (by Sony) as having the SLT-A65 focusing system mounted in an adapter.

It has the SLT mirror in the adapter, for better or worse, and the screw drive motor needed for Minolta AF lenses. Unlike the LE-EA2, it allows a full frame image circle to be covered (I guess the EA2 encroached on this with some pretty important bits).

There are cheaper adapters, some much cheaper, they will not auto focus a screw drive lens. Sony's LE-EA3 is probably cheaper, will support full frame, but will only auto focus select lenses that are compatible (I think they need a SAM or SSM motor built into the lens), and folks have reported it's pretty slow.

Third party adapters with no AF support are probably available and much cheaper, but you'll want to verify how they manipulate the aperture, unlike older MF legacy lenses the Minolta AF lenses are designed to have the aperture closes with a lever from the camera body. Some adapters might only allow you to shoot wide open, I have seen one that has a "ring" for the aperture. I've never seen a third party adapter mentioned that supported AF.

Yes, but if you plan on using larger, heavier lenses, you might appreciate the solid build AND the integrated tripod mount in LA-EA3 (if you prefer MF) and LA-EA4 (for AF). The cheap adapters will be MF only, and no electronic control. LA-EA3/4 technically convert an E-mount body to an A-mount body (in case of LA-EA4, the camera is literally converted into an SLT with mirror-based PDAF as in Sony A65... you also get AF Micro Adjust feature which can help you adjust any focus issues with a particular lens). Having a chip will also allow you to look into third party A-mount lenses that have optical stabilization.

As for the lenses themselves, I have both. They are both very good lenses. The 35-70/4 is tiny (comparable to a 50mm prime lens and only 49mm thread), the 70-210/4 is longer (but not unreasonably thick... only 55mm thread). It is an internal zoom design, so length stays the same at all focal lengths.

The 35-70/4 focus fast (may have to do with smaller lens elements), and is sharp wide open. The 70-210/4 does fine wide open but really shows up at f/5.6-f/6.3. This is the 70-210/4 at 75mm, f/6.3:

And this is 35-70/4 at 70mm f/4:

And here are the two lenses (the two on the right):

(Minolta 28-85/3.5-4.5 and Sigma 24/2.8 on the left)

And here are two of my telephoto zoom lenses (Minolta 70-210/4 next to Sony 55-210/4.5-6.3 OSS), both with 1.7x teleconversion lenses (Sony HG1758 on the Minolta, Sony DH1758 on the Sony). The Sony when zoomed in, extends to the same length as the beercan:

The idea of a NEX mounted to a tripod with a Beercan attached to it is really a scary thought!

why not an A99, then you won't need a converter and you'll have IBS?

Not when you're using any of the LA-EA adapters as tripod mount is integrated into the adapters.

I can't find any info about those teleconverters.  They also don't look the same despite the same model number.  I assume these go on the front of the lens and not on the back?  Founf nothing on Dyxam database.

Could provide more description?

These are teleconversion lenses that go in front of the lenses. Both require 58mm filter size so I have step up rings (beercan has 55 to 58mm, the Sony 55-210 has 49 to 58mm). The TC lens to the left was made by Sony for a video camera and is quite heavy and big... Better on non extending lens like the beer can. The DH1758 is smaller and fairly light. I believe it was made for a Cybershot stills camera. Even Sony R1 had one but it was bayonet mount. Coincidentally, I can use either of these on my F828 as well as it has 58mm thread.

An advantage to this approach is that you can multiply optical reach by 1.7 with negligible light loss. The 210mm lens becomes 360mm or a FF equivalence of 540mm. They are very good quality lenses but I will recommend their use only at longest FL.

These aren't made anymore. I suspect Sony might come up with another for RX10 but that will be either 62mm or bayonet mount.

Hi I'm using sometimes the mentioned Minolta 35-70mm f/4.0 on my 24mp monster Sony Alpha 65. While I like this lens and the images are good, compared to the primes and my Sony 16-50mm f/2.8 it fell behind them. But only if you pixel peeping and if handhold shooting. If on tripod and carefully manual focused and a little bit stepping down the aperture, the images are very detailed and clean with that Minolta.

That is my experience on APS-C A-Mount. Got the lens for 20,00 €. It should work with an adapter on any Next. But on an A-Mount camera you have stabilization too.
