Quick question please, for about 8 years now I've used the Panasonic Lecia DG Vario Elmarit 8-18mm F2.8-4 lens as my super wide on my Olympus system. It's a nice and sharp copy, and has always served me well.
As it's my only non Olympus lens, I've recently been thinking about perhaps swapping it out for the Olympus 8-25mm F4 Pro. Now the obvious advantage is the extend focal length (50mm equivalent vs 36mm of the Lecia), making it potentially a good walk about lens. Downsides are a) it's constant F4, whereas at the wide end the Leica is a F2.8 b) It's an extending zoom, whereas whilst the Lecia is also really an extending zoom also, it only extends inside the confines of the lens barrel itself and so doesn't change the length of the lens at all and c) potentially the better weather sealing of Olympus lenses (although I've used the Leica in light rain with no issues).
However my main question is does the IBIS work better at the wide end on Olympus bodies rather than Panasonic lenses ? It might just be trait of Olympus / OMS bodies, but I've always found when shooting videos on the OM-1 at the widest setting (so 8mm or 16mm FF), that when walking, I tend to get a lot of wobbling (jello) at the edges of the frame. I've tried all combinations i.e. just IS or IS + Digital as well as adjusting the IBIS strength in the menus from -1 through to +1 with no apparent real effect. I therefore always wondered if this was more to do with the lens than the body, and if an Olympus / OMS lens would work better with the IBIS in that regards ?
Anyone with these lenses that can give any real world experiences please ?
