In fact, LA-EA5 has one major drawback when migrating from A-Mount. It doesn't recognize TC.

Recent mirrorless cameras can perform image plane phase difference AF even with F22 (contrast AF is possible if it is higher than that).
F6.3 is usually the AF limit for single-lens reflex cameras, and F8 is the AF limit for recent high-end models.
With the higher sensitivity of the sensor, you don't have to worry about the shutter speed even with a small aperture, and there is also image stabilization. In other words, with a mirrorless camera, you can use a much smaller aperture and more compact lens. Actually, I use ILCE-1 + 200600G + 2xTC, 1200mm by hand. No need for a monopod.

However, A-Mount does not benefit from this. For example, you should be able to AF even if you attach 2xTC to 70400. In fact, 200600G + 2xTC (F13), which does not require LA-EA5, can be AF. However, LA-EA5 and TC cannot be used at the same time. Since it is treated as without a lens, it cannot be stopped down.
If you have 300 / 2.8, you would be very dissatisfied with not being able to use TC.


I am confused by the TC issue - can you not use your E mount TC between the camera and the LA-EA5?

All this is why I find the in-camera Clear Image Digital Zoom an effective alternative. Main drawback is shooting JPG only. Main advantage is cost (£0.00).

Here's an enthusiastic article about it at B&H Photo, https://www.bhphotovideo.com/explora/photography/tips-and-solutions/sony-clear-image-zoom-the-most-amazing-shooting-mode-you-never-heard.

It cannot be physically attached because it interferes.
There may be exceptions, but E-Mount does not physically attach TC to lenses that do not support TC.
I don't know if this is a deliberate design.
ILCE-1, FE:14/24/35/STF/135/10400GM, 90M/24105/200600G+6, 1.4x/2xTC

LA-EA5, A:35G/100S/200M/500R,3x-1x +7, SIGMA MC-11 + Canon EF8-15 FishEye

Also, you are off the topic of LA-EA5.

There is no reason why you shouldn't use optical zoom with cropping or super-resolution. Both, not either.

I like to use 1 in APS-C mode. Equivalent to 1800mm in FE200600 + 2xTC + APS-C mode. This is the size that the moon fills the screen and is the limit that I can handle.
You can also add super-resolution processing with software such as LightRoom.

Bird photographers say that 600mm is the standard lens. 1800mm is only a medium telephoto lens.

Thanks, all seems a bit OTT from Sony.
