Hey! You finally did a detailed review of this lens. Thank you!
May I very gently suggest that it might be better not to promise that the review will be done in the current month (whatever that month may be) if you know it will really be another eight months before you can get around to it. It just causes frustration among your loyal user base.
Now if you could only get around to testing the Canon EF 400L f5.6, I know there would be a large number of bird photographers who would be grateful.
