Yes, very true. Besides, I took a lot of pictures with normal-speed film in dull light and at dusk or near darkness. Obviously the shutter speed usable depended on the lens and the support, but with a standard 35-50mm lenses I had no trouble getting pictures down to 1/15 acceptably sharp handheld (appropriately braced) and up to a few minutes with a pocket hand-tripod.
Mind you, that was in those far-off pre-pixel-peeping days!


I do find IBIS & OSS very useful with teles, though if you need to get slower than you can hand-hold with normal FL lenses, you can get trouble with the subject moving, which neither IBIS nor OSS can cure!

I suspect you're right - but we can always hope.

What the next Minolta AF to E mount adapter really needs to do is as little as possible - no mirror, no AF, just a screw drive motor that responds to the cameras as a motorised lens would while focusing the lens.

Its a curious sense of timing that you say the below. I've just found a youtube video that in a non-scientific way implies that the AF is quicker to focus than the a7-III.

a6400 review and a6400 vs. a7-III AF speed test

Hmmmm....

Not that its a worthwhile comparison to me anyway since I'm certain that I'm sticking with an aps-c body.

Thanks for the reply, addy landzaat.

The AF of the A6400 is amazing. Just keep the shutterspeed a little higher when using non-stabilised lenses and you will be just fine.

There are passive shift adapters for A-mount to E-mount. An active one would have to move much more mass than just the sensor, but theoretically it could provide stabilization. Stabilized gimbals already exist that handle the mass of a camera and lens.

I had the situation this past Sunday of using a stabilized Sigma lens on my A77II. I took a few shots before remembering to check which stabilization systems were enabled. They don't play well together. I was doing a lot of panning shots so I opted for Sigma OS Mode 2 on the lens with Steady Shot Inside disabled.

Hi everyone.

Thanks for all of the in-depth replies.

It was one of those "half awake/under-caffeinated" kind of questions that occur at a random moment really. Not something I had really considered before even though I have (and still do) weighed up the pro's and con's of getting either an a6400 and a6500 and using my a-mount lenses via either an LAEA-3 or LAEA-4 adapter.

The jury is still out on that one especially now the price of a brand new a6500 has finally fallen to below £1000 GBP (through a local retailer). An a6600 is quite out of the question due to budget reasons!

Thanks again.

3 options for image stabilization .
1; buy a body with in body image stabilization .
2 ; but a native lens with optical image stabilization .
3 ; if your adapting lenses , buy a canon eos lens with optical image stabilization in it .

As noted an adapter can't have image stabilization built into it .
Optics would have to be added to it which could only be optimised for one lens , anything else would be a compromise like generic teleconverters .I would imagine it would also be extremely expensive .

I'm not really expecting anything to be honest, just wondering if such an idea would have many takers or, as it appears, would be worth the trouble to design and produce in the first place.

I have a gut feeling that even if such an a adapter was available, the cost would make it prohibitive to most users.

Thanks.

I don't see how. IBIS moves the sensor, and OSS moves a lens element. The adaptor has no sensor and no optics. What are you expecting to shift in the adaptor?

I think image stabilisation is "nice to have" but far from essential.
It can help in certain situations but it doesn't give a guarantee for shake free shots, it just increases the probability to get it.

Two of my main cameras don't have stabilisation (A6000 and A7) while the third one does (A7ii), but I don't see a big difference in discarded shots due to camera shake between them. The only thing is that I prefer to use my A7ii with longer lenses, where shake can be more of a problem.

Secondly I think such an adapter would be hard to make, OSS in the lens can be exactly tuned and placed in the optical group for the lens/focal length, while in the adapter it's always (far) behind the rear element and needs to work well from very short to very long lenses. Not a simple endeavor by any means.
