It is a very long process to clean the Aperture Oil in a Pentax Takumar 28mm 3.5 SMC but it is well worth it as this is a great little lens and are easy to find. Just make sure you have a spanner before you start repairing the lens.
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.
The Tou/Five Star 28mm f/2.8 Auto MC is not the most exciting lens in the world at all. Color and build were decent but thats about it.
Want a really poor lens? Check this JC Penny 28mm f/2.8 MC out. yupee…
This old Soligor 28mm f/2.8 Wide-Auto is a decent little lens for it’s day. It can produce some decent photos stopped down but it’s not worth getting too excited over.
This Nikon Nikkor 28mm f/2.8 Ai is a lens definitely worth looking for! With a cheap Ebay adapter it can be put on many DSLR’s. The lens produces amazingly sharp images. Most people want the Ai-s version but miss out on the optics of this amazing lens making it a very cheap 28mm 2.8! The focus is absolutely amazing and everything works great.
