Defects in Manual Lenses and lens buying advice

This blog is mostly about manual lenses which are usually 30 to 50 years old. And while most of them are surprisingly reliable the are a few things you should check before or after buying a lens.

This checklist is based on the experience I gained from buying  more than a hundred lenses since I discovered how much fun it is to use them on Sony’s Alpha cameras.

If you have additional info about a defect not listed or disagree with my assessment please leave a comment!

Scratches on the lenses

Use a large light source like a window and place the lens between you and the light so that you can see the colorful coating of the lens.

Scratches are seldom a problem in the real world but they lower the resale value of a lens. In theory they could reduce the contrast of a lens or cause some flare but I have never seen that happen.

You can’t really do anything to restore coatings but it sometimes makes sense to fill larger scratches with black paint to avoid light scattering.

Useful Accessory for the Sony Alpha 7: A L-Bracket

What is a L-bracket?

A L-bracket is a peace of metal which serves about three functions:

  • It makes it possible to mount the camera in portrait orientation on a tripod
  • It is a more solid connection to the camera than quick release plates because it has a much bigger area of contact to the camera.
  • It increases the size of the grip and makes holding the camera easier.

Old against New: Zeiss 2.8/28 vs Sony FE 2/28 vs Minolta MC 2/28

I wanted to see how my new FE 2/28 compares against my older manual lenses, so I ran a comparison between four lenses:

  • The Minolta MD 2.8/28 is very small, light and affordable
  • The Carl Zeiss Distagon 2.8/28 T* enjoys a very good reputation and it is a bit more expensive at around 250€.
  • The Minolta MC 2/28 is the oldest and fastest of the bunch, it was introduced in 1975. My copy has some fungus in it and other copies might be better.
  • The Sony FE 2/28 is brand new and the most expensive one at 450€.
