300mm l f/4or 70-300mm L

hi
i need some advice with regard to the above lenses
lenses will be used for general wild life/nature
which one has the best iq at 300mm
is it better to go with the 70-300 because its a new model and has beter IS.
any comments would be helpfull.

The 300mm is hard to beat and it accepts the 1.4TC with decent results.
The 70-300 is versatile, sharp, more expensive and does not work well with a TC ( only the Kenko Pro is compatible, it will not work with a Canon TC)

My $0.02 says go with the 70-300L . I have had both and I enjoy the zoom over the prime lens .... there both vg .......

300 for wildlife. if you go with the zoom you will find yourself at 300 all the time anyway. carry a 70-200 and a 1.4 t/c if you want versatility.

300/4 will be better at 300 even f4 vs f5.6 but theres not a lot in it.

The extra stop of speed is quite useful though either for the shutter speed or the 1.4tc

300/4 is weathersealed too, is the 70-300L?

Yep

Don't forget that the 70-300 has 4-stop IS while the 300 only has 2-stop

300L f/4 IS isn't weather-sealed... 70-300L is.

Hmm thought it was vs the non sealed 400/5.6. Ah well.

hi
thank you for the replys.
i think i will go for the 70-300, mainly because it has the zoom
all the reviews seem to be devided on which is best so i suppose the only way is to dive in and buy the 70-300

thanks all
