Hello people!

While I'm waiting to pickup my new A7RIV I'm going nuts about the corresponding lenses to enjoy it.

I already have a A850 with some glass which I expect to keep: Sony 50mm f14; Sony G 70-400 f4-5.6 SSM; Sony 85mm f2.8 SAM, KM 28-75mm f2.8 (Tamron later Sony), Sony 100mm f2.8 Macro; plus a few cheap M42 lenses and A mount APS gear which I'm going to sell.

BTW I still use film cameras for B/W, so those lenses have good use in my mINOLTA 7 ETC-

I am counting every dime left, and I need a good quality standard zoom for the new camera.

The decision is between a brand new native E mount Sony 24-105mm f4 or to buy a used Sigma 24-105 f4 for A mount + LA-EA3 or a used Sigma 24-70mm f2.8 IF EXG HSM + LA-EA3, which would save some good money anc would find use with my secondary camera and film equipment. Does the LA-EA3 induce flare? Does allow the latest AF wonders?

I shoot a lot of portraits and people, social events and urban landscape, both for work and personal projects. You can see some of my stuff at www.instagram.com/manuini (I'm refreshing my webpage, sorry).

Sorry for such a lenghty post!

Manuel from Buenos Aires

Just get the native Sony 24-105mm. Its a very good lens and you will really appreciate its quality and weight savings on A7RIV.

If you plan to use AF-C bursts, the Sony LA-EA adapters only AF at the slowest frame rate on the A7RIV. The EF or SA versions of Sigma Global Vision (i.e., post EX) lenses with the corresponding MC-11 don't have that limitation. They get all the native AF modes and even embedded lens profiles like native FE lenses.

However Sigma doesn't support the latest A-mount or E-mount stuff even with their native mirrorless offerings. The not quite yet available Sigma 24-70 DG DN Art FE lens doesn't support the native lens performance updates Sony made in 2016. The Sigma A-mount Art lenses don't support the native lens performance updates Sony made in 2011.

The SEL24105G is the most up-to-date FE normal zoom.

Thank you guys for your kind responses. It seems my money is going towards the Sony 24-105G.
One last question: is the Zeiss A mount 24-70mm f2.8 + LA-EA3 adapter a better combo?
I'm not into nature photography or sports, the slower burst rate suits me well.

!Gracias!

You'd be better off with buying the new sigma ART 24-70mm f2.8 FE version which is priced rather nicely or the tamron 28-75mm f2.8 FE version.

I generally find A-mount lenses which I enjoy using on A-mount cameras feel long and cumbersome when adapted to E-mount*. The Sigma 10-20mm, for exmaple, which is perfectly fine on the A58 but adapted via LA-EA2 just feels silly and wrong.
So despite my original intetions I'm gradually getting compact MF primes for E-mount. Latest two are the esxcellent (recently upgraded) Meike 35mm f1.7 and Samyang 12mm f2, both of which are great to use and have brought back much of the fun of photography.
But I guess I'm not in the best position to discuss AF performance with adapters ...

*Edit: I forgot to mention the Sony SAL85f2.8 which is still pretty light and small even when fitted to LA-EA1/3, like the other easy-choice primes, and the combo is stil smaller and lighter than most E-mount 85mm offerings, if that matters to you.

considering you could have got FE85/1.8 for £370 on offer last week doesn't make much sense to buy the SAL85/2.8.

There are very few a-mount glasses that are worth adapting and they are mostly telephotos that e-mount lack or don't have cheaper alternatives for. Even then you are better off adapting canon EF glass because Sony won't do a screw driven LA-EA5 which supports all the AF modes. And honestly MC-11 from sigma seems to be better supported than LA-EA adapters in terms of firmware updates. Pretty poor show by Sony IMO in terms of a-mount glass support but then there may not be much ££££ in it for them to care.

I did not think that was the point that Miranda was making, but as you are. The Sony A85/2.8 costs 240,- and you can get a LA-EA3 for 160,- making it 400,-. The Sony FE85/1.8 costs 650,-. So, it is much cheaper.

The support Sony gives us with the LA-EA3 is just fine - I would like a better screw mount option, but in general, it is fine. It is not a poor show by Sony IMHO. You simply expect to much.

I would get the FE85/1.8, it is a great lens if you're looking for a fast sort tele lens But it is all off topic.

@Manuel: Do I understand that you have the Sony A-mount 28-75/2.8 SAM? Just get the LA-EA3 and just use that one. I do not find lenses in this zoomrange useful (that is just me) and I have none for my A7r2. The Sony 24-105/2.8 seems to be a fine lens, but if you need/want the f/2.8 the Tamron seems the cheapest good option.

I do not know what lenses you use the most and for what, but did you consider some primes like the FE55/1.8 and FE85/1.8?

please re-read what I have written. FE85/1.8 can be had much cheaper than your quoted price on the many number of occasions it has been on offer.

And that's your opinion. I only expect as much as what the competition offers i.e. canon.

Currently it's only one competitor (Canon) that does a bit better with adapters and as far as I know they don't have something as advanced as "real time AF" that the later A7's and A9 have. Even their Eye AF isn't as good and very "young". So you can't have it all in one camera/brand so there's always choices to make. To call something "bad" because it's not meeting your needs, but competition is lacking in other aspects is a bit selective judgement in my mind. My opinion vs. yours, no more or less

£105 from CEx in the UK. I think mine was less than that from LCE a year ago, s/h. I don't see much point in buying A-mount lenses new, and if you buy an adapter that can be shared between lenses.

I re-read it and it says the same thing as the first time I read it Yes, you probably found a place where they sold the FE85/1.8 for 370 GBP. What shop was it? Does the shop offer full (EU consumer protection) warranty? That is not a normal price and not one that is matched by any of the shops in The Netherlands or the shops I regularly check in the UK.

Comparing a one off price is useless, you should compare the normal prices.

amazon, was on for £420 and there is £50 cashback on top at the moment in the UK. It's been on offer a fair few times recently, wouldn't be surprising if it was on offer again.
