    Posted: 04 August 2020 at 15:30
Do you think I will be disappointed with image results, if I were to change my A99 for an A7Riii plus a LAEA* adaptor?

I can't afford to change my lenses at this stage, so an adaptor is my only choice, as much as I dislike the thought of using one. I understand that using an adaptor may compromise things like focus, but I am hoping I would get used to that and work around it, but image quality is something I do not want to compromise on.

My ultimate goal is to cut down on equipment weight and bulk by having one E mount body and a few E mount lenses.

The 42MP sensor that it shares with the A7rii is, in my humble opinion, outstanding, compared to the A99 sensor I think it will be an upgrade. In terms of the LA-EA3 and 4, both have a slight shutter release lag it seems. PRM talks about it at 04:00 here https://www.youtube.com/watch?v=F38WE6w9OKg

The LA-EA4 is a bit limited in terms of AF points, but it works. IQ wise I cannot see how you'd lose anything. Some say the high MP sensor is demanding but I don't know, I've not noticed this camera working any less well with vintage lenses than the A7.

I have the a99 and the a7Rii. So not a perfect comparison but close.

Depending on the lenses and adapter used, there will be handling, speed and possible focus issues when compared to the a99 with native A mount. However, you will not see a decline in actual image quality. The 42mp sensor without the AA filter was a revelation for me. I mostly use it with MF Leica and Voightlander lenses, and it blows me away with how good the IQ is.

I find the results of a7Rii/LA-EA3/SSM lenses to be excellent IQ, though these lenses will always have better handling, speed and sometimes focus accuracy on the a99. The LA-EA4 gives me the ability to use all my screw focus lenses in AF, but isn't as advanced, so some issues in focus accuracy and speed are evident.

The a7Riii is a more advanced camera than mine, so your differences will likely be even less.

Depending on your use case, the limitations of the LA-EA3/4 might be a problem. If you do not need continuous AF during bursts, the adapters will be fine.

The A7r3 has the 42mp sensor that is great. It sits in my A99m2 and A7r2 Why would it be less then the older 24mp sensor in the A99? With everything being the same, more pixels always are better.
Did you consider the A99m2 btw? It is smaller then the A99.

Lets consider your worst weight case. You use the A99 with the 70-400G I assume. That combination weighs 2262g (1500 + 812), the A7r3 with the 100-400G weighs 2052g (1395 + 657) - still heavy, but less

Weight and bulk savings with E-mount might not what you hope for. It depends on what lenses your looking at.

Unfortunately there are zero A99ii in South Africa, new or 2nd hand, and zero back up of any sort for A mount

I get that. When Sony pulled the A-mount from NZ it was a major push for me to move to the E-mount.

Personally I've found the a7Riii to be an amazing camera and the first E-mount camera I'd consider a replacement DSLR. I shot an event last week and despite the low light and slower 24-105mm f4 lens, every shot was in perfect focus. What's more the pics were great despite the camera selected an ISO6400 (I had flash, 1/100s and f5.6 dialled in, and AUTOISO. Didn't realise it would go so high!).

The smaller form and some E-mount lenses really let your downsize the gear you carry on a hike. I'm using some of my smallest bags now on expeditions.

The a7riii even leaves my a77ii behind in autofocusing, so while I don't have an a99 (c2012), I do have an a77ii(c2014). That may give you a useful data point to compare, as you have an a77ii also.

I got the LA-EA4 when I had an A7R, which was the right decision then because the A7r had a terrible autofocus system. But I understand, especially with SSM-like lenses, the LA-EA3 is better. You can use the camera's autofocus system, which in the case of the a7riii is very effective. I assume you will know that an adapter does introduce one more step to the data flow between the camera and lens so it will not be as quick as a native E-mount lens.



a77ii- and some Sony/Minolta A-mount lenses.
a7riii- Zeiss Loxia 21mm, Loxia 35mm Loxia 50mm, Loxia 85mm, Voightlander 110mm Macro, Sony 24-105mm, Sigma 100-400mm.

Yes, and it is the one small thing that does bother me about using the adaptors, but quite honestly if I want to move on with Sony, economically I have little choice at this point in time.
Thanks

I own both and use the LA EA3 and La ea4 adapters. The A7riii is the hands down winner. Especially if you have La ea3 ssm lenses. No Bayer filter means much nicer detail in photos and your iso is now much more usable right up and past 6400.
Of course there are some nice e mount lenses you can snag at a good price too and once you move there..you start leaving your old a mount glass at home.

It looks like I would need both adapters, as one of my favourite lenses is the Zeiss 85mm f1.4, which is screw driven

That's starting to make it an expensive and bulky transition.

Lucky for you...or something, that 85mm lenses aren't few and far between on E-mount. Rather well-regarded most of them. For AF there are the Samyang 85/1,4, 75/1,8, Tokina 85/1,8, Sony 85/1,8, neither which costs significant amounts. In addition there's the GM 85 1,4 which does cost, and also the upcoming Sigma 85 1,4. These may not render precisly like your Zeiss but chances are you'd like one of them at least and operationally they will all be more pleasant to use than the LA-EA4 I can almost guarantee.

You can still manually focus the Zeiss 85mm with the LA-EA3 though. And the magnification options on the A7riii (plus focus peaking) does make this a more viable option.

While the manual focus might be the second-best option (saving money and space in your camera bag), you might find buying an E-mount 85mm, selling your Zeiss 85mm and not buying the LA-EA4 worth contemplating.

I was in a similar situation to you. I had the Minolta 85mm f1.4G that I sold and was able to buy a Viltrox 85mm f1.8 (which is the same lens as the Tokina BTW) and had some change left. To me it has the same or similar responsiveness as the Sony or Samyang glass (both of which I have tested); and does not have the let down of needing an adapter. There are plenty of reviews on the web, should you wish to peruse. I am very happy with the change.

Yup, I would have to go the route of manual focus initially, as I really don't want to buy the LA-EA4.
