Considering it too, so why not rent a TC and see what happens?

Looks pretty good on sharpness alone:

But I don't know how AF speed, contrast and colors are affected.


Some of my lenses focus beyond infinity...!

Ok this is officially confusing? You want to know how the EF 300 f4L IS w/1.4tc compares to the EF 100-400.. naked? You state you'd like to try one out... you have a 300 f/4 IS AND 100-400 listed in your sig!

I guess i'm confused that you asked on here.. shouldn't you already know the answer. :confused: Are you saying that you don't have a 1.4x tc?

Raymond i suggest you purchase the economical Kenko 1.4 MC4 DGX which is rated very nice and your cash outlay will be minimal just to test it out.

With that being said i dont feel you will see any significant improvement and only will gain 20mm.

I sold my 100-400L and i can guarantee you the 400/f5.6 prime copy i have is sharper then the 100-400L @ 400 i used in my testing:

http://www.the-digital-picture.com …omp=0&FLIComp=0​&APIComp=0 (external link)

300/f4 IS + 1.4 @ f5.6 420mm versus 400/f5.6 naked prime:

http://www.the-digital-picture.com …omp=0&FLIComp=0​&APIComp=0 (external link)

I dont miss the IS of the 100-400L or the 300/f4 IS and the AF is much faster with the 400/f5.6 prime.

A nice monopod costs less then a 1.4 TC that degrades the IQ on any of these lenses mentioned :

http://www.bhphotovide​o.com …Swivel_Tilt_Hea​d_for.html (external link)

Now if you could afford the stellar Canon 300/f2.8 + 1.4 your IQ objectives would be easily solved since IQ remains excellent on this lens and the 70-200/f2.8 MKII.

Regards, ;)

okie dokey. :oops: I use the combo, and it's pretty sharp. AF might be a tad slower than the 100-400.. mine hunts a little more, and you really have to pay attention to the focus limiter. Otherwise..it's lighter, cheaper,not a dust-pump (hehe), and you can get some beauty shots at 300 @ f/4 and tack sharp @5.6. :D

I have a sharp 100-400. I tested a 300f4 and a 1.4 TC, and for everyones raving about this set up I was left unimpressed. Well perhaps I should rephrase that. No better than my 1-4. Have your 1-4 callibrated and you'll forget about the 300f4.....

I have both the 300 f4 and the 400 f5.6 and sometime i still put my 1.4x TC on my 300 f4 if I need just a little more reach or I want IS. AF is way slower on the 300 with the TC compared to the 400 prime. I use my 400 prime for 99% of my shooting though.

I have the 300 with the Tamron 1.4x tc and IQ is solid. It's not as good as the 400 but usable. I do feel like it makes the 7d meter odd and a little inconsistent. Almost seems like spot metering or the background is over exposed. I have not tried any other tc with this lens and it is the non reporting type.

No... i was just saying that an advantage of the 300/tc vs 100-400, is you can take shot's at 300mm f/4..giving some beautiful blur/bokeh and faster shutter speeds; with the zoom, you can't even reach f/4. ;)
