Two months ago, I had

Sigma 17-70

Vivitar series 1 70-210

SMC-A 50 f1,4

Takumar bayonet 135 f2,8

Takumar bayonet 28 f2,8

I found a nice deal on a F-50 f1,7, so I purchased it and sold the A f1,4. So far so good. I also ended up with a Pentax-A 28-80 and a Vivitar A 70-210 (and a P30t body).

Then I found a great deal on a SMC-M 150 f3,5, so I purchased it.

Then I found a good deal on a FA 100-300 so I purchased it.

Yesterday I found a deal on a FA 50 macro so I purchased it...

I refrained from buying the FA 28 f2,8 that came with it, at least.

Now I have three tele zooms, two medium tele primes, two standard zooms, soon two fifties (arguably one macro). The wife is starting to breathe fire...

I can convince myself to sell the Pentax-A 28-80 and the Vivitar A 70-210 easily. I can't decide if I want to sell either the 135 or the 150 (I'll be keeping at least one). I'm having a hard time convincing myself to sell the series 1 even though I got the 100-300 to replace it. Strangely the easiest lens to sell was the A 50 f1,4, although a part of me misses it.

I still look at listings on Craigslist and Kijiji. Maybe I need to stop doing that
