have you used it to learn basketball? my god how bad its beaten. FA lenses have lots of plastic ring inside, I would never buy one of those in that condition, even free.

Nope, heard a technician and the response is its a very risky operation. So I sent it back for refund.

SMC PENTAX 1:4/20 the early K mount 20mm with 12 elements in 10 groups

Just bought, arrived today. I'm looking if its fixable before sending it back. (Seller told it was perfect, fluid, clean, bla bla bla.. )

Thank David. I'm not thinking to fix it myself, I'll look for an experienced tech.

You guess it is balsam separation?

I don't think I will find another lens to get the cemented group, I have never seen another (in good condition) on sell... anywhere... (except Japan)

My dear fellow pentaxians, I have a 20mm K series (12 elements in 10 groups) with fog in it. Can you help me? Is it balsam separation? Oil/grease condensation?
How much and can it be repaired?

Thanks
Marco

Hi Mark88, I purchased this lens off John at the start of this year https://www.pentaxuser.com/forum/topic/fs--pentax-smc-k-20mm-f4-63055

I'm having a break from Pentax at the moment, and was intending on keeping it, until I got another body. But I guess that's a waste, if someone could be using it.

Send me a message if interested. Cheers, Neil
Thanks Neil, but I read the lens has a haziness problem. I need one in perfect conditions but thanks for your message.
Cheers
