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.

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.

Just bought A6600 after my A77ii died. Mainly had a suite of Minolta lenses, including 50/100mm macro, 35-105 old style, 80-200 f2.8, and the sony 16-50 f2.8.

The main thing for me with the LA-EA5 is that I can gradually replace these lenses over time - I simply can't afford all their replacements at once. So, with the camera, I bought the Sigma 18-50 to replace the 16-50 (although I'm not sure it's quite as good to be honest - but perfectly fine for a walkaround lens). And over the next 5 years or so, I may be able to get a native e-mount macro, and then maybe a telephoto or a wider angle prime. But the adapter gives me all the flexibility I need at present. It doesn't add much weight or size to the A6600, the body and adapter are still slightly smaller than the A77ii.

So, treat it as a transition tool - rather than a direct comparison. I guess that's how Sony see it.

PS - the 35-105 Minolta is excellent on the A6600 with LA-EA5. Possibly actually better than it was on my A77ii (faster, quieter and lovely pictures).

I haven't seen a third-party teleconverter that emulated a first-party one so far. The third-party ones either just past all the electrical connections straight through, or add chip(s) that modify the focal length, aperture, and motor drive.

Chipped Kenko Tele Plus teleconverters work on the Sony LA-EA adapters. The DGX and (some of?) the Pro 300 ones allow working AF with SSM/SAM lenses.
