Bush Rummager 4,769 Posted January 5, 2010 Report Share Posted January 5, 2010 Couple here using my new Canon extender 2xII (curtacy of the bearded one ), only been out with it twice.. still not sure what to make of it to be honest, lost quite a lot of focus speed, seems to hunt for ages somtimes.. and obviousley lost a few stop aperature wise (now f5.6 right through), .. but then again going from 200mm to 400mm does come at a price i suppose... ah well.. Two diffrent Robins by the way.. This one is right out at 400mm f6.3.. This one 350mm f7.1... both stopped down a tad to try and gain a bit more sharpness... Still learning all the time! so any comments/advice more than welcome.. Quote Link to post Share on other sites
Coyotehunter 689 Posted January 5, 2010 Report Share Posted January 5, 2010 Nice shots , are you using a crop body or FF ? Quote Link to post Share on other sites
MuttleMcTuttle 21 Posted January 5, 2010 Report Share Posted January 5, 2010 Not bad quality for a 2x... They do tend to f**k up the AF though Quote Link to post Share on other sites
J Darcy 5,871 Posted January 5, 2010 Report Share Posted January 5, 2010 Maybe a 1.4 gets you the best of both worlds??? Quote Link to post Share on other sites
Coyotehunter 689 Posted January 5, 2010 Report Share Posted January 5, 2010 Maybe a 1.4 gets you the best of both worlds??? The 1.6 TC iS what i have , the only thing with the x1.6 TC is you loose the AF on the 100-400, but you can cheat by putting tape over the last two terminals and it works Quote Link to post Share on other sites
Bush Rummager 4,769 Posted January 6, 2010 Author Report Share Posted January 6, 2010 Cheers folks.. the body is a 450d wich is a 1.6 crop (i think), so i am actually getting that bit extra length, i'll hang on to it and give it a fair crack of the whip but if things dont improve then, yep, i'll be swapping it for the 1.4 version, will i get any auto focus speed back by switching to the 1.4?? cheers..

Romany 1,065 Posted January 6, 2010 Report Share Posted January 6, 2010 (edited) I have a 1.4 on my Nikon set up,and coupled up with my 300mm lense its incredible sharp, and AF works fine..I had a bigma on the same camera, and the 300mm + converter produces far better images. Yes Ive lost a stop, but my camera is designed to give good results in low light, the results speak for themselves..the second robin isnt bad for what your using, and for early attempts Because of where and in the way canon converters are mounted, image quality sharpness and contrast will be affected with all but the best lenses, and loosing 2 stops is a lot for most lenses. To get the best results using this converter on canon, you will need something like their 300mm f2.8 lense, then you will see some good results Edited January 6, 2010 by Romany Quote Link to post Share on other sites

Wich Nikon body do you use? i'll admit now to knowing nothing about Nikon gear.. being a total novice and all that, but the 450d i'm using is only an entry level body, so perhaps thats somthing to look at?... thinking about it, might just know somebody with a 5d body to do a bit of testing with my lense/converter combo. Like the point about picking up A 300mm 2.8, surley that would solve all my problems... but not for £3k pluss!! .... not for taking piccys of my two mongrels and ducks down at the local ponds!!... if i ever get to go to the Golapagos islands.. then, ye.. maybe.. but for now, looks like i'll drop the x2 converter..

Look forward to seeing how you get on with the 1.4, think my next purchase would probably be a body upgrade.. at some point in the future.. top kit is just so fooking expensive..
