Message: <blockquote data-quote="shoshone" data-source="post: 1508598" data-attributes="member: 55655">Lots of 100-400 owners on POTN (Canon) have observed that it takes quite some time to get used to using this lens. I sort of agree with this.I believe our own Keith Reeder posted lots of advice in this regard and he managed to 'learn' how to get the best from his (as if he needs to learn anything <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" />. However it does take time so give it a chance Chuck.Regarding getting closer as has been mentioned a lot, I'd rather emphasise trying to get more distance behind subject/bird from it's background However far away the subject is and yes as wide open as you can get away with. This should give the lens a chance to produce a better bokeh rather than the harsh grasses and reeds which Chuck is experiencing.Personally I think Chuck made the right decision and just has to learn how better to exploit the lens he bought. I moved from a 70-200 bog standard F4 to the 100-400 and never looked back. Yes I'd love to have a 300 F2.8 and stick my 1.4 TC on it, or even a 2 x TC but that is dreamland for me.In addition, I always felt disappointed sticking a 1.4 on the 1-4 until I put it on my 1DIII and changed my mind. Enough ramblings though.Jamie</blockquote>
