My recent habit of photographing birds had me wanting a little extra reach so I decided to pick up a TC. After researching (mainly reading
this thread), I decided to try to find a Tamron 1.4 TC. Obviously they're discontinued and at one point, it seemed like prices were reaching into the $200+ range. I didn't want to pay that much but I decided to try my luck on eBay and found one that was still at a low bidding price and eventually won a brand new one for $59. I just got it today and wanted to try it out on my DA*300 but unfortunately it's raining a bit here. The DA* may be weathersealed, but my DS isn't
I did try a few test shots in my backyard under cover and I'm extremely pleased with the IQ. AF speed was the same as well. I'm eager to try it some more when the weather clears up.
I also ordered the DA* 50-135 yesterday so that should pair up nicely with the TC as well. Hopefully these two new acquisitions will satisfy my lens and gear buying for a while ...
