eb.com... Has anyone here used the Canon 1.4X telextender *with* the 70-300mm zoom? The lens I refer to is this one: http://tinyurl.com/67e3xrb Max Hello Max. The Canon 1.4 extender is only compatible with a subset of Canon lenses. I think the subset does not include the 70-300mm f4-5.6 lens. Have a look at : http://www.usa.canon.com/cusa/suppor...der_ef_1_4x_ii http://www.usa.canon.com/cusa/suppor...Specifications I _think_ there may be problems with the back of some lenses hitting the front of the extender. Regards, Ian. |

Look at the possibility of a Kenko or other third party TC which might not have this limitation. |

The lens I refer to is this one: http://tinyurl.com/67e3xrb This zoom lens is probably not good enough to give you quality with an extender. You should use a very high quality zoom lens or a fixed focal length lens for an extender. Additionally, most cameras won't autofocus with this lens and an extender, as with a 1.4x extender the effective aperture at 300mm is f/8. You could try: - Canon's 400mm f/5.6 lens - Canon's 100-400mm f/4.5-5.6 lens - Canon's 300mm f/4 lens with an 1.4x extender each reaching ca. 400mm and f/5.6, but each solution is way more costly than just the extender. You could also look for third-party lenses (but check first if they're good) ... there are some offers for -400mm and even -500mm zooms. Then there's the mirror lens, cheap, but terrible bokeh. -Wolfgang |

Canon 2X telextender on EF 70-200 with 20D? | Bill Hilton | Digital Photography | 11 | March 9th 05 03:35 AM |
Canon should be totally ashamed of this (and some others too) HP got this basic and absolutely essential thing right in their little digicam that's cheap even for a P&S, so why can't Canon?!!
