[QUOTE="Fortkentdad, post: 631926, member: 24285"] [ATTACH=CONFIG]263298._xfImport[/ATTACH] I decided to put my Tamron 70-300 to the test with the Kenko TC. This is the Tamron Di 70-300 F/4-5.6 USD with VC (it was on). The TC is Kenko's 300 PRO N-AF 1.4 model. On the D7100 in it's yellow jacket. I was not using a flash for these shots. It works. It has some drawbacks. Of course you lose some light - it becomes an F 5.6 to F 8. And it isn't as quick to focus - hunts too much - way too much. For still subjects, this isn't an issue. [ATTACH=CONFIG]263299._xfImport[/ATTACH] managed to focus in the shadows well enough, took longer than I'd like but got it. [ATTACH=CONFIG]263300._xfImport[/ATTACH] Even a running dog can be managed - some of the time, keeper rate wasn't great with lots of blurry running dog shots. [ATTACH=CONFIG]263303._xfImport[/ATTACH] Birds on a wire - sure [ATTACH=CONFIG]263304._xfImport[/ATTACH] BUT BIF shots - well I was not able to get this hummingbird ... qualifies as an "almost" shot [ATTACH=CONFIG]263305._xfImport[/ATTACH][ATTACH=CONFIG]263306._xfImport[/ATTACH] But that bird was darting about and it may be my lack of Hummingbird shooting experience but I could not get a focus before it flew away. It did give a reasonable shot of a dragonfly - at rest - the dragonfly in flight were too blurry to keep. [ATTACH=CONFIG]263307._xfImport[/ATTACH] These shots were taken in the evening - low level sun. Not dark but not mid-day sun either. Conclusion I would not use it for birding unless I really really needed the reach, and it was bright daylight. It would be OK for sightseeing where you wanted extra reach. Could easily be added when needed, but that is a bit of a bother. Tomorrow I will try again - this time without the T.C. for comparison sake. [/QUOTE]
