<p>Thank you all for your contributions. I decided to send the lens back, as I didn't want to send it across the world for cleaning by a competent technician. I managed to get a new mint one that's already on it's way. Hope I'm more lucky this time. </p>

<p>Hmm... I contacted two different companies to get estimated price for cleaning the lens, but none of them would do it. They said they wouldn't be able to get spare parts if something should brake during the repair/cleaning.</p>

<p>John, there's also a video on youtube about fixing stuck aperture blades on a breech-lock FD 50/1.4. It looks manageable, but probably a New FD 28mm lens has a different design.</p>

<p>Thank you for replying, Jim. Sounds like it's a job for professionals, and probably it will cost too much to be worth it. Better start looking for a new one.</p>

<p>Hi,<br> I recently bought a Canon New FD 28mm f/2.0 for $150. The lens is cosmetically and optically in mint condition. However, there is oil on the aperture blades. I'm now wondering if I should return the lens to the seller or try to fix it myself. I have successfully dissassembled a Canon 50/1.4 LTM lens because of stiff focusing ring. After cleaning and re-lubricating the helicoid, it works perfectly. How hard is it to dissassemble a New FD lens? Will cleaning the aperture blades fix the issue, or do I also have to re-lubricate? It's hard to send it back because it's optically wonderful and a fast 28mm is what I need (and they are not often up for sale). What would you do?</p> <p>Thanks in advance for input on my dilemma.<br> Per-Chr.</p> <p> </p>
