    Posted: 07 December 2020 at 07:21
Now don't get me wrong, I'm loving my A99ii and if A-mount had a a long future I'd stick with it but as it sits right now if my most used lens (Sigma 150-500) were to bite the dust I'd be stuck with having to hunt for a second hand replacement of some sort.

So the thought goes to some kind of transition towards E-mount with the G 200-600 and possibly also a TC-1.4 in the mix. Budget would be rather generous, as the only way I could do this kind of transition is a likely coming redundancy from work. After 19 years of service the severance pay would come out to be a decent chunk of change.
That's not to say it's unlimited, if it was the A9ii and 600GM would be in the cards

So my thoughts are somewhere along the lines of this.
Kit 1: A7RIV, G 200-600, TC-1.4, LA-EA5 and grip...making use of my old Minolta's.
Kit 2: A7III, G 200-600, TC-1.4, Grip plus a few native lenses to make up the difference.
Possibly also Kit 2 with an LA-EA4 for a "budget" setup.

Main bit I'm up in the air about is how the 7RIV or 7III handles the G 200-600 plus TC-1.4. And also how the old Minolta's (mainly the Beercan era lenses) hold up for focus and IQ on the E-mount bodies.
Anyone have any thoughts on the matter?

Is it wrong walking around nowadays hoping to get fired?

A7III cannot AF-C/PDAF past f8 AFAIK since my A7RIII couldn't. So 200-600mm+1.4x won't at long end since it'll be f9.
A7RIV/A9/ii can though. Also if you can afford an A7RIV you should be able to afford the cheaper A9 which has better AF than both A7III and A7RIV. since you are not looking to go out and buy this immediately might be worth waiting for A7IV.

A7III and A7RIV are very different bodies. While your Minolta lens might do fine on A7III think they may not be the best to put on A7RIV. Of course you won't get AF with A7III and screwdriven lenses. Also which Minolta lenses are you going to be using? There are some fairly cheap but good lenses available from 3rd parties these days for e-mount.

Even with the A7RIV from all the reviews I have seen while screwdriven lenses do AF they are no where near as good as native lenses.

Getting fired and the "golden boot" are different. The latter is kinda nice in many ways and former is an unpleasant experience for everyone involved. While I have never experienced either myself I have been involved in a colleague's process for latter because of my position and it sucks. I know friends who been through the former and all of them have come out of it better off and happier

AF and IQ will not change when moving to FE mount, perhaps some of the modern AF features will work when using the LA-EA5 on A7Riv, but it remains screw driven AF with inherent limitations. In any case it will not get worse. If you're satisfied with these lenses now, you will remain so.

W.r.t. 200-600+1.4TC on A7iii all I can say is that AF has proven to be accurate, fast and reliable in AF-A mode, even in our abysmal Dutch December weather.

In your position I'd wait a while for the a7IV - even if that camera is not for you, its presence will have an effect on pricing of other models... The LA-EA5 would incline me towards a newer model that could handle it, although the LA-EA4 works fine, I worry about the AF mirror getting damaged.

Although A mount screw lenses won't work as well on the newer mount than native stuff, I'd be happy enough with working well enough and somewhere close to how it works on an A mount camera - generally it is shots at small apertures that will likely notice most as I think there is a slight delay in the solenoid stopping down A mount lenses.

It is an odd experience, I put in for voluntary redundancy about 9 years ago - I knew it was the time to go when I realised I would be resentful if they didn't accept me, but also that I'd still feel insulted if they did. Not quite sure when I transitioned from 'Angry young man' to 'Grumpy old git', but there it is...

Later on I found out that they were intending to move my 'policy and projects' group to be up near the Secretary of State's outer office (Michael Gove at that time, Note that other politicians from other political parties may also be insufferable...) With my talent for holding my tongue, I don't think I would have lasted a month...

Well worth it though and would have been a month well spent

Do you get PDAF on A7III when the lens is at the long end i.e. @840mm f9??

Michael Gove - the absolute definition of the term "Acquired Taste" I suspect. I think you made a good move there, Bob!

The A7III PDAF works down to f/11.

I wouldn't say the 200-600G AF is fast.

Ah ok that's nice, the A7RIII was limited to f8 for PDAF, so I wrongly assumed A7III was the same.

I don't find the 200-600mm slow, in fact I find it to be the fastest one in it's class. The 100-400mm was slightly faster to lockon or acquire focus but once you have your subject in focus the both do equally well at tracking the subject.

Since you're interested in the 200-600, won't you consider a smaller sensor for a longer EFL?
I'll probably get the 200-600 sometime in the future exclusively for birding and my thought is to use an A6500 or so to get the most of the FL.
I'm pretty lousy at stalking and tracking and hence would try the option of a longer length.

He is thinking about the A7RIV which will give more reach than any APS-C body sony produces atm.

For future proofing?

I'd start with the A7Riv. The a7Riii is superb but you're already 3+ yrs behind the tech. Then build the lens collection around it.

I personally don't like the LA-EA4 on the E-mount. It's bulky with the SLT module, you get few AF points, and they're all clustered in the centre. I mean, it was fine on the A7R but that had an appalling AF system in comparison to the post-A9 era cameras.

a7riii, a9- Voigtländer 15/4.5, 110/2.5 M; Zeiss Loxia- 21/2.8, 35/2, 50/2 & 85/2.4, Zeiss Batis- 85/1.8 & 135/2.8; Sony 24-105/4 G; Sigma 70/2.8 M; Tamron 150-500 f5-6.7; Sony SAL 135/2.8 STF

That shows how ignorant I'm about the E-mount bodies. I'm still stuck in the A-mount. Would like to get into birding but the 200-600 seems to be the best "budget" lens and hence that's what I'll most likely get next year or so.
Need to educate myself a bit.

Anyway, back to the OP's discussion...

A7rIV gives a 28mp compared to the 24mp of the APS-C cameras - not really a relevant difference.
