Tamron 1.4 TC

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 ...

Good find! I'm curious as to your results with the DA* 300mm. According to Tamron's specifications it is designed to be optimal for the 50 to 135mm focal length. Which, of course, would fit your DA* 50-135 like hand in glove!

AFAIK, I don't think Tamron is producing them anymore. But, some places may still carry old stock of it.

I'll be sure to post up some sample photos with the DA*300 + 1.4TC combo when I get a chance. I have four days off work next week so I'll be putting that and the 50-135 to work

I discovered earlier this week that my copy of the Tammy 1.4 pairs nicely with my Siggy 70-200mm f2.8. Much better than when I use the Sigma 2X APO TC instead. I didn't note any real degradation in focusing or sharpness, either.

Might help if I include an example, wouldn't it? Shot wide-open at 280mm. Full-size crop, straight RAW to jpeg conversion. No PP except for a bit of Clarity at 25 in ACR (it's my default for all my images).

Doesn't the tamron TC have the contacts for the "power zoom" feature of some FA* zoom lenses? I am wondering if the SDM would still work when using a DA* lens in combination with the TC. But seeing that you have a *ist DS, the SDM probably doesn't work, right.

I'm not sure about the power zoom feature on the FA* lenses, but if you check the thread that I linked to in the first post, they have a long discussion on the Tamron TC working with SDM. It seems like you need to get the one that's MC4 and it'll work. And yeah, SDM doesn't work with my DS.

Yes, the MC-4 is fully sdm/hsm compatible.

Yep I have it and it works fine with the Sigma 70-200 and the DA*300.

The only problem I've encountered is that I lent it (and the 300mm) to my son before the holidays and still haven't gotten either back
