Like you, I have an 'allegiance' to IBIS and the Minolta 7D was my first serious digital camera for exactly that reason. Pre-digital I shot almost entirely with Kodachrome 25. Anything that allowed me an extra stop or three was more than a blessing ... it was nothing short of miraculous. Now we have cameras that are 'clean' at ISO 6400 or even better (8 stops from K25) and I am in heaven. Perhaps IBIS is not so important anymore but in my mind it is if only because it was the first technological development that woke me up to the real advance in possibilities that digital provides. It is a good time to be a photographer to be sure!

As far as I can remember, the K-M 7D has a handy little meter thing that showed how hard the IBIS system was working, which meant you could better predict how well it was actually going to stabilise your shot.

Regarding IBIS, I will say that in my X-T4 it is good but not outstanding (not Olympus level). It handles my shaky hands well. I rely on it for sharp shots between about 1/10 of a second and 1/60. I often shoot at those speeds in the woods.

The big Fuji's still haven't reached my personal "Rebel" price point. I'm quite happy with ASPC so far, though I do oooh and aaah over the detail and richness of the sample files from the medium format. If they come out with a rangefinder style version at $2999 with a nicer viewfinder and IBIS that might push me over the edge...

The Canon camera was the 300D, it was the camera which got me in the Canon system. And now I have more lenses than I can carry. But I still have the 18-55 that came with the next camera I got the 400D or “xti”.

I am thinking that the 50SII + the Metabones 0.71x speed booster is the best solution to get the most out of Hasselblad lenses. Certainly I am looking at that option.

Still using my Sony a850!

". . . in some other cameras such as the Panasonic GX7 the feature seemed almost not to work;"

Early µ4/3 cameras had a real problem, shutter induced vibration. On my first trip using an Oly and a long lens, I got confusing, frustrating results; this shot fine, that one with motion blur. Oly had a solution hidden in their menus, shutter delay, from the beginning, but never referred to it. Panny had no answer until shutter redesigns and Electronic First Curtain capability.

With the GX7, Panny introduced both shutter delay and electronic shutter.

Shooting an Oly E-M5 and GX7 side-by-side, extensively, with the Oly shutter shake supression and the Panny ES on, I concluded that the two IBIS systems were equally effective.

You were probably experiencing shutter vibration blurring, and attributing it to poor IBIS.

All old news now.


Sorry to hear you didn't have a great experience with the Pentax IBIS. My K1-II IBIS has always worked, unless my hands were shaking too much. (It won't work miracles.)

Pre-production cameras wouldn't have the final software tweaks, nor any updates. I'm not sure if a software problem caused sub-optimal results. By the time I bought the K1-II, Pentax probably had all the bugs worked out.

One great advantage of IBIS is that I can use old Pentax screw mount lenses with the adapter (always get the Pentax adapter) and IBIS works with them too.

Now, the autofocus set to automatic and using the entire field doesn't reliably focus on the subject I want to be in focus. I use the spot-focus setting and manually focus the lens. If in doubt about the focus in dim light, I rely on the in-focus light in the viewfinder display.

[Oh no, the ones I was talking about were MUCH earlier than the K-1. Things like the K-7 of 2009. --Mike]
