The enclosed photos represent a 35mm efov of 450mm and 900mm and were taken with the Sony A6300 using the $1,200 Sony FE 70-300mm F4.5-5.6 G OSS lens. The 900mm (35mm efov) results from using the camera's Clear Image Zoom feature (it is different from "digital zoom"). The alternative was to buy a Sigma 150-600mm lens and MC-11 adapter. Has anyone gone that route?

The list of compatible Sigma lenses that will work on Sony cameras with the MC-11 adapter is at: http://briansmith.com/sigma-mc-11-lens-adapter-compatibility-list/

I was told that using the Sigma 18-300 with the MC-11 would not provide adequate resolution with my A7rM2, but probably only because it's full frame. I sure wish it would work.

I am using the $500 Sigma EX 100-300 f4 with the A77II and 2X CIZ. for the 900mm equiv. FOV.

My bad math - 810 EQ. .....

I have started using the Clear Image zoom on my RX 10. It is a viable option, and with the image size set to L and the aspect ratio at 3:2 the files are still 10M. They are very sharp.

Absolutely beautiful shot!

Nikonian72 is accurate but, since incomplete, inaccurate. Please see my view of the EXIF showing the 35mm equivalent.

BTW, In my tests with both the a6000 and the RX10m3, the clear image zoom is useful for video but is simply not as good as cropping on the computer, especially if you avoid the problem of successive compression when you edit jpgs (a whole different subject).

Maybe you could explain this comment in more detail someday with examples ?? - in your own thread ....

Another alternative, which would require the Alpha lens with an adapter (yes/ no?) would be the Sony SAL-70-400. When I rented one of those and a Tamron 150-600 G2 during the same week recently, I felt I was getting better results with the Sony lens even though I had to crop a bit to equal the size of the Tamron image. I have a brand new, in box, Sony (3 not 4) adapter that works in that application. I described that set of experiences in previous posts on this forum. I have not advertised the adapter for sale yet but I'm pretty sure I really don't have a use for it after all because I bought at RX10m3. I used a rented adapter so mine has never been out of the box. PM if interested, anyone.

Changing the size of a sensor does NOT change the focal length of a lens. Why not show the "equivalent" of same lens on medium format, or APS-H format, or 4/3 format, or 2-inch format, etc.?
If you attach this lens to your cell phone, you would have 2,283-mm "equivalent". The actual focal length NEVER changes. And the "Digital Zoom Ratio" is also completely independent of both the focal length and the sensor size "crop factor". DZR is an additional electronic cropping, loosing half of available pixels to 'appear' as if zoomed by lens.
