Kenko 300 AF 1.4x with FA 50mm?

I don't know if this works, or works well, but has anyone used this with a prime such as 50 f/1.4 to get added reach? Good idea, bad idea, just downright lousy idea?

hinman paired the Tamron 1.4 to the FA50 for some interesting results
have to find it tho

i would certainly not advocate that as a solution to get more distance for a short prime

I tried out a Bower 2X Teleconverter. The idea was to get more range with my 50 and 70mm and sell my "plastic-tube"-->Tamron 70-300mm f/4-5.6

After some test shots and reviewing the pros and cons, I kept the Tamron and sold my teleconverter a few days later.

If you need more range and are on a budget, I recommend you try it out. It costs maybe twice as much as a cheap ebay telekonverter, but you'll have ten times more fun with the Tamron.

Tamron 70-300mm is best below 200mm with the aperture a few f-stops higher. It's NOT great, but good enough for me.
70-133mm - f/4.0
133-220mm - f/4.5
220-300mm - f/5.6
