Hope this is the right place to put this. My current longest reach lens is a Canon EF 70-300 mm 4-5.6 IS USM zoom . This is to me an excellent lens. Wanting a little more reach, the GAS is there to buy another longer reach zoom. Some years ago, B&H had a sale on a Vivitar Series 1 1.4x AF. I bought one for about $70. It has not been widely used. Yesterday photos were taken using the 70-300 with and without the multiplier. The attached six photos are as taken with no alteration. The camera used is an M50 on a three-legged monopod. The camera was set on program mode. I may have avoided the GAS attack. Any comments are most welcome.

Generic TCs are designed for longish FLs, favoring lenses with glass at the rear end rather than hollow tube. In your lens the rear glass moves quite a bit and at 70 to ~100mm may possibly collide with some dedicated TCs. IOW it seems a much safer match with the generic.
The test images show a very usable combination. In real world nontest use it should look even better.
Check your exif to see whether the camera “knows about” the converted FLs. If not, then it’s best to assume the IS is about 1 shutter speed less effective for your hand held usage. IS is self adjusting based on FL data from the lens, so you wanna see if the data reflects the longer, converted, FLs or it doesn’t.

I too am impressed with the results, both the lens and the lens w/ the 3rd party extender. Attached is look at the 1:1 pixel-level details and some thoughts on usage and addition technical testing.

I like the combo. Works well for you, but you’d better get a 600 just in case. (And Canon would appreciate it too.)

All:
The dog statue is a memorial to the best dog I ever had and I have had more than a few. He was a mutt who wandered up to the house of my niece near Latta, SC. As we drove home with him as a puppy my daughter said, due to a narrow white streak down the top of his head, he looks like Pepe la Peu (sp). I immediately said you have just named him: Pepe! The statue is in need of repainting. With the exception of the head stripe and a white spot on his neck, he was solid black. We had him cremated and his ashes are there.
