At some point I hope to get off my butt and include photos or examples of this stuff and include other items that I've had experience with, but for now this will have to do.

Again, feel free to share your experiences on products that you've purchased.

Congrats on the new toys Tom. Like I mentioned , the 70-200 f4 is a stellar lens. Don't let the price or the fact it is not one of the more expensive versions fool you. It produces top notch photos.

I have been wanting some of the Kenko extension tubes myself so that I can use them with my 400mm L and be able to get a closer focusing distance. The nearest I can get right now is 10 1/2 feet :look:



Keep us up to date as you get to play with them more and more.

They may work fine for that lens. My only concern is that although they connect to the lens and camera by metal, there is a plastic barrel in between. They may be strong and solid, but a heavy lens would have me cautious.

Here's a quick test of my Yongnuo YN600EX-RT Speedlites and YN-E3-RT Wireless Transmitter. I put the speedlights on tripods with umbrellas and set them to ETTL. I played with the ratios. The left is 4 to 1 and the right is 8 to 1. The lighting ratios don't seem to be accurate to me, but that may be an error on my part with the set up. I'll play with it more when I have the chance. Used my Canon EF 70-200mm f/4L USM Lens for these with a simple two light set up.

Here are some quick shots where I played with the Kenko DG Auto Extension Tube Set, using different tubes. Again, it was a quick test. As a result, my lighting sucks. The tubes attach easily and stay in place. They work well, but as expected, the auto-focus is a bit hard to obtain at times, especially when using the larger tubes. These were hand-held. Of course, when getting in this close, using a tripod would have been better. I wanted to give them a try with hand-held because most of the little critters I shoot don't stay still enough to use a tripod on. I took these with the Canon EF 70-200mm f/4L USM Lens set to f/22 I think.

Very nice Tom.

Seems like the speed lights are doing good. I am with you about the ratio. That lens sure is working well for you.

Hope to get more practice with the flashes in today. I've got a niece's 4th birthday party to attend.
