Legacy Lenses - Buyer Beware!
Feb 21, 2013

I have just bought a Minolta Rokkor MD 50mm f1.4 on eBay from a seller with a pretty good satisfaction index. Lens advertised as 'very good condition'. When it arrived I couldn't wait to fit it to my NEX-6. I took some photos. Trembling with anticipation I popped them into Lightroom, and - What! What's this! Have I sneezed on the lens? Is there axle grease on the rear element? Is it mounted properly? Are my eyeballs the right way round? Absolutely dreadful!

Hopeless at f1.4.  Pretty poor at f2, getting better at f2.8 and so on but always soft at the top right corner.

Take a look:

Rokkor MD 50mm f2

The camera was mounted on a tripod, and the shutter fired by way of the self timer. I was particularly careful with focus, using both peaking and MF assist, and focusing each time.

I have put further examples in an album in my gallery:

I've yet to convince the seller that this is a substandard lens!

However, I've been much luckier with a Helios 44-2 58mm f2 which outperforms my Rokkor in every way.

Caveat Emptor, and all that.
