Hi,

I would like to purchase a macro lens for my Nex-5. How good would vintage/legacy manual focus macro lenses be on the NEX as opposed to the AF

They are different lenses:

SEL30M35

  • Maximum Magnification: 1:1 (1.0x)
Canon FD 35-70 mm macro zoom lens
  • Maximum Magnification: 1:5 (0.2x)
Canon FD 28-55 mm macro zoom lens
  • Maximum Magnification: 1:4 (0.23x)
Canon FD 50 mm f3.5 macro
  • Maximum Magnification: 1:2 (0.5x)

Consider which macro level (1:1 or 1:5) you need.

Then, a longer FL enables you to be further away from your subject, given its maximum magnification  level. However, at large magnification, this is always short.

The SEL30M35 does 1:1 magnification at extremely short distances, so lighting could be an issue (e.g. you'll need a ring LED or ring Flash light).

But for small objects, you can get incredible amounts of detail.

The SEL30M35 is great for studio work. If outdoors, you'd be using it more like 1:2 or so.

Alternatives would be the SEL18200 OSS or the Vivitar Series 1 70-200 as a legacy MF lens. Both have decent magnification at reasonable distances. I'd guess that these have magnification factors of around 1:2.5 or so.

You can increase the magnification ratio on any lens using extension tubes or by adding a diopter in front of the lens, something else to consider.
