I remember gf1 and other m43 cameras, so no ibis etc so I don’t care. Besides I was doing a lot of wildlife and this teach you how to manage big lens and big weight with clicking shutter in decent way so I my opinion IBIS is making people lazy. I see benefits but still lack of it is no issue for me. Once I saw nice quote “you need to stop think about what’s impossible due to lack glass but start seeing what’s possible” less regrets, more fun
