I'm looking for a lens with as long of a focal length as possible but i dont have $3,000+ do drop on new glass. Can anyone provide any help with previous use of canon prime lenses 300mm or greater. Will the 400mm f5.6 be good for anything other than daylight? Also, how do the 300mm f4 and the 400mm f5.6 do with the 1.4x extender?

The 300 f/4 is superb for the money spent. The auto focus is fast and accurate and the IS is a plus as well. It is sharp, with good color, contrast, and bokeh. While mounting a 1.4TC I have had mixed results. In a series of aviation shots about 33% came out great, another 33% had some quality loss, and the last 33% were out of focus. The combo is still usable for me, but only when I absolutely have to.

I can't speak for Canon equipment but I have a 600mm f4 nikon lens that I periodically pull out to sell on ebay. I spent 5k on the thing, now I can only get about 1500.00 for it as it is manual focus.I also have a Nikon 300mm 2.8 AF ED that I have xtenders for and have great success with due to the 2.8 speed of aperture. If you want power, go with a dedicated 400, 500 or 600 manual lens.I say this because the type of targets you shoot with a lens of such power is easy to track focus with these big lenses,AND you can pay little for them on ebay type locations.If your going to rely on 1.4 and 2x xtenders, I would make sure the prime lens you are attaching them too is a fast lens, say 2.8 as xtenders cut down your light. Also when you add more glass groups, it's better that your lens is ED type (low dispursion).Always put your biggest $$$'s into your lens...Hope that helps shed some light on mega glass....PS...I have decided to keep the 600mm as it takes phenominal pix.When using this powerful a lens I found it best to put the camera on manual anyway as any light source deviation,(like during sunset shots) is better controlled w/ manual settings...j

The 400/5.6 is really a bargain but it lacks IS and is a daylight lens. The 100-400 doesn't rock at all in little light so the prime, IS-less, should rock less.  Silly
