The most comprehensive, understandable and trustworthy guide.

Great book, easy to read, appreciate guidance.

I’m a happy camper! Great course overall—just a small complaint: the printouts could be a bit clearer. Some fonts are too small or look a little soft. Still, excellent material and presentation!”

great!

Fast delivery, and good Course

Nice, well documented, and pedagogic presentation.

I am a newbie to photography, wanted to have a hobby shooting wildlife photos, finally got Nikon Z9 and a telephoto lens. I am glad that I came across John's Z9 camera guide and lens guide, he is very simple in his teaching approach and yet covers all the basics you need to know. I have tried many PDF tutorials and you tube videos, but nothing comes close to the visual slides of information John provides in his guide. I highly recommend his guides for anyone.

I recommend this guide. I recommend John Greengo Photography.
