Juan 65
I have had my 300 for about 10 years and I am now shooting it as you are with the 7D. I am not fimiliar with the micro +12 that you are referring to can you tell me where I can find out more about that? I have never been real happy with mine and maybe that will help.
Thanks
Thank you for the info, that's deeper than I ever would have gone. They say you can't teach an old dog new tricks but you just schooled me.
Hopefully that helps, I rarley use this lens because I have never been happy with the results and I could certainly use the extra distance to narrow down the mountains I climb to chase critters in Alaska. I have been going to my 70-200 F4 with a 1.4 TC. I will let you know how it works.
Thanks again
Phil
Who says the 300/4 + 1.4x II is too slow for AF? Yes, it can be used for fast action--and not even on a 1D-series body. You just have to know how to work with it.
5D2 + EF 300/4L IS + 1.4x II @ 1/1600s @ f/8 @ ISO 640.
Up until this year, Juan, I used the 300f4 for everything. Very useful lens, lightweight, IS, f4, sharp, can't beat that! I used a teleconverter for years. And two canon tubes. I don't think it matters which brand tubes you use. The off brand teleconverters for instance the Tamron focus faster than the Canon. I have both.

You might consider faster shutter speeds. Handholding this lens on your cropper is like shootin' 480mm,
good long lens technique imperative for crisp shots. Those crow shots are all soft.
Here is an actual N&W picture with the 300/4L IS. My sincere apologies for the previous two images--I will remove them if anyone objects. In my defense, the planes threw me off...? Okay, so that excuse doesn't really fly.
