    Yes, I am aware, but maybe something what those people are experiencing is somehow related to what Jeff is experiencing. Maybe somehow they are connected??

    Jeff, please take a look at the sites below showing focus issues with the 70d. If you have seen these already, then disregard, but maybe it can help others.. http://photorec.tv/2014/03/70d-center-focus-point-issue/...

    I read on another site a guy with a 7d2 with focus problems, below is a quote from him.. "On Saturday I took several bird pictures with my 5D Mark III and then on Sunday with the 7D Mark II; same place, same lighting situation. Camera settings quite similar although I left the AF tweaks on the...

    New Sigma 150/600

    I find Jeff's captures and post processing just fine. It's sharp and clear and more neutral in colours. I find most photographers that's been around since the film days are more appreciate towards neutral natural tones, rather than eye popping over saturation and overly contrast and overly...

    Gorgeous capture, Mick! :) ..I do notice the spots, hmm, that is interesting. Please let us know your findings. Cheers, John

    Chris, both are super gorgeous shots! :) ..I do love seeing your "super sized" orginal size view of your pictures on Flickr. Yes, there's now many great examples of the quality of images this lens is capable of. I still think it will be great to post pictures from experiments either from camera...

    Super pictures, Chris and Mick! :) I think Jeff does it best, to post it here and also have a link to his Flickr to see it there too, the best of both worlds. ;) Cheers, John

    Super capture, Jeff! ..I really like the pix you posts here, it shows up really nicely in size and detail, even better than seeing the original sizes on Flickr. :) Cheers, John

    Isaac, How about doing this to prove yourself. Shoot a picture with your Tamron 150-600mm @ 600mm of a bird using RAW, then provide us the RAW file so we can see just how good a photographer you are. How about it? John

    This will be the last time I will talk to you about this, you know the old saying.. "If you don't have anything nice to say, don't say anything at all."

    Isaac, I think you did a great job in replying! I think sharpness, like beauty, it's often times judged in the eye of the beholder. And let the truth be known, it's often left on a persons expertise of knowing how to post process an image using the best softwares. I know a photographer friend...
