Thank you all for the feed back,especially Troy-well done mate,on spotting the beak was slightly out off focus-i was interested to see if anyone noticed that.
Indeed i did go to F4 and took some pictures,that came out very well too,The reason i started at F 2.8.was it was very early morning and wanted to see what this lens could do,i really have'nt used it much since
i bought it,its easily as good quality as the L 400 prime.
Now i wonder if there was another photographer standing next to me with the F 4 version of this lens,and we took the same pic,would there be much difference?if i had been using F 4 with the F2.8 lens?
given that the F2.8 version is 10mm wider,does it work(IQ) quicker than a F4 version?in this sort of circumstance?
Thank you Troy for your comment,so many times people post photos,and there is very little interlectual feed back,also with this photo posted,i did want to play with the shollow depth of field,and aim right at his eye.you can see reflection of post and me in it on cropped version.
So ,no Troy-not picky at all,i am so gl;ad you picked it up,well done!
go to top of the class!
