I had been interested in getting a 1.4x teleconverter for my lenses but I don't own any lenses that are compatible with the Canon brand tele's, so that leaves the A/M ones like the ones made by Tamron. I currently own the EF 70-300L IS USM, EF 100 Macro and 28-135 IS USM. I wanted to try it out using my Canon 7D.
I have a photography friend who owns a Tamron 1.4x MC4 (non pro) and she let me borrow it for the day at a trip to our local zoo. It was overcast so it was going to be a great test to see how well the AF worked in lower light situations. I have to say that I was very impressed with how quickly it locked on focus 99% of the time. Only at full zoom on my 300mm did it hunt on occasion, but even then, it locked in pretty quickly.
I got home and went through the photos and the image quality was incredible. The images were very sharp and detailed.
I did a search and found a used Tamron 1.4x at KEH for 65 bucks. I used it this past weekend and it worked fantastic. It correctly metered the aperture ( I.E. f4 instead of 2.8 ) and worked well with all settings (I.E. Av mode) I couldn't be happier and would recommend getting one if you have been interested.
The extra reach on my zoom was worth the couple of times it had trouble locking on. The way I look at it is that I can always take it off if lighting is really poor or if I can't risk not getting the shot. I also really enjoyed using it on my 100mm macro, it not only gave me a longer working distance from the subject, it had a magnification factor as well that was awesome.
Just FYI in case anyone was interested in getting a 1.4x tele.
