Well, cruising Ebay tonight, I couldn't help but buy two lenses. First I found a Tele Takumar 200mm F5.6 Preset for $56.00 shipped in near new condition. I've been wanting one since getting my Tak 200mm F3.5 Preset (my now favorite lens) to see what the difference is. I could NOT pass at that price.
Just a couple of minutes later, I stumbled upon a Tele Takumar 300mm F6.3 Preset for $89.00! It looks like it is in great shape and comes with the original lens hood and case but no caps. Some of the images taken with this lens look very similar to what I am getting out of my 200 F3.5, so I'm REALLY excited to get this one and start shooting wildlife with it. I can usually get very close for the 200mm to work great, but that extra 100mm will come in handy in some occasions.
If I end up liking the Tele Tak 300mm F6.3, I'll probably end up selling my much used and liked Sigma 70-300 APO as I probably won't be using it much any more. I REALLY prefer to use the Takumars over any other lens, so I'll sell the Sigma to recoup nearly all of the money spent on these two lenses.
I can't wait for them to arrive and start comparison shooting! I'm not much good at scientific comparisons though, I'd much rather be out there in the wild shooting landscapes and wildlife. BUT, for these lenses, I might try to concentrate and do a nice comparison.
Sorry to be grabbing up all these Takumars, I just can't resist them, especially at these prices
