Clean aperture oil 28mm 2.8 Promaster Marexar

This video shows how one can disassemble, repair, and reassemble these Promaster MC and Marexar CX MC 28mm 2.8 lenses. The problem is not always the aperture but more likely just the mechanism in the read mount that gets sticky from old grease.

Chinon 50mm f/1.9 Auto

cannonfast — Thu, 14 Nov 2013 00:59:26 +0000

This little Chinon 50mm f/1.9 Auto is a lightweight lens but is built pretty cheaply. Also Optically it is simply not too exciting. Chinon usually produces some decent lenses, but this is not one of them.

Pentax M 40mm f/2.8 SMC

cannonfast — Sun, 10 Nov 2013 04:38:31 +0000

If you want a fast & super tiny lens then this Pentax M 40mm f/2.8 SMC easily fits into your pocket and is fun to use. Image quality isn’t amazing but it has very little distortion and almost no ghosting.

Pentax-A 100mm f/2.8 SMC Macro

cannonfast — Mon, 28 Oct 2013 05:17:29 +0000

There are some extremely amazing lenses out there and this Pentax-A 100mm f/2.8 SMC Macro is a prime example of mechanical and optical perfection. However this is a hard to find lens and still costs just as much as a newer auto focus 100mm macro lens even today. For perfect focus I would check Ebay to see if you can get a split focus screen for your body.

Sigma 85mm f/1.4 EX DG HSM

cannonfast — Mon, 28 Oct 2013 04:38:36 +0000

This Sigma 85mm f/1.4 EX DG HSM is a fantastic lens for the price with quick focus, sharp photos and really nice bokeh producing some really nice portraits. For a while I went crazy telling everyone around me to go out and buy one because they are so good.

Bell & Howell 85mm f/1.4 Aspherical IF MC

cannonfast — Wed, 23 Oct 2013 22:24:54 +0000

This Bell & Howell 85mm f/1.4 Aspherical IF MC is a fantastic lens for the price if you don’t mind manual focusing. I would get a split focus screen from Ebay for your DSLR to make focusing easier. This lens comes in many names other like Samyang, Rokinon, Bower, and Pro Optic but are all made by Samyang so look around Adorama or Ebay for deals under the other names.

Vivitar 28-85mm f/2.8-3.8 MC Auto

cannonfast — Wed, 09 Oct 2013 03:56:54 +0000

At the wider end of this Vivitar 28-85mm f/2.8-3.8 MC Auto it performs fairly well and is a decent f/2.8 zoom lens for what they sell for these days.

Ricoh Riconar 55mm f/2.2

cannonfast — Mon, 02 Sep 2013 06:15:43 +0000

I feel bad for the people who bought their nice new Ricoh camera with this Ricoh Riconar 55mm f/2.2 kitted with it. This lens is very poor. However if you want some strange and artsy spherical aberration, this lens is interesting to play with.
