GH5 GH5 IBIS, lenses that don't vignette and work nicely

[Peter Berry]

So, any experience you guys would like to share regarding which lenses work well with ibis?

Basically, every lens without OIS works perfectly with the IBIS as long as you input the right FL if dumb adapter used. And IS-Lock in video mode great with all my legacy fast primes up to 200mm, as well as my native 7-14/4.0 and 25/1.4.

Of the OIS native lenses I have, only the 12-35 (v.1) works with OIS and IBIS in concert, and it's very good. The 100-300 (v1) has weak OIS, but no IBIS with that off. With OIS on and IBIS on the IS-lock icon appears in video mode, but little apparent effect.

My excellent workhorse adapted 4/3 Pana-Leica 14-150/3.5-5.6 has pretty good OIS, no IBIS with OIS off, but a big Video IS-lock effect with both on that's pretty striking at 150mm. Whoopee!

The Canon 100-400-II w/ Metabones T-smart adapter and excellent 4-stop OIS: if turned on with OIS off, IBIS takes over with about same effectiveness as the OIS - possibly a bit weaker at 400mm. IS-lock also, but little effect beyond 200mm.

Finally, Panasonic, why the devil isn't IS-lock available in 4K/6K Photo or any other normal stills mode?

Thanks. Yeah I am just looking for first hand experience. I know most should be fine with an 0.71 speedbooster.

Also one for Panasonic: make a frekin normal lens, withouth a flybywire focus ring!!!!! Why can't we have a normal lens that we could use a follow focus with it aaand use dual is. I mean this is THE dslr for video, but the lenses are for dads shooting vacation videos. C'mon panny, take a hint from Sony

To be fair E-mount Sony lenses are fly by wire and so are Olympus along with most other auto-focusing mirrorless lenses. It it not ideal but you can learn to live with them and they can actually do some really useful things like focus transition without an expensive and bulky follow focus.

Oly lenses aren't manual? 12-40 2.8 for instance? I know lots of sony lenses arent manual, but they still do offer manual lenses.

No, Oly are not since they went to MFT mount. The old four thirds lenses had mechanical focus. The 12-40 has hard stops but it is not mechanical focus and the focus markings are not necessarily accurate.

 

[KINOKS]

Oh I see. I saw that they had hard stops, so I just assumed they were manual. Either way, I presume focus pulls are repeatable, so a FF can be used right? This is what I was talking about: being able to use a FF with lenses. For the price point of this lenses and the Sony ones, I don't care if they are really manual or not, as long as focus is repeatable and a FF can be used then great. For truly manual, cine glass with correct witness marks I don't expect to pay so little

One more thing about the Oly's: 12 - 40, it's focus ring can be pulled backwards, thus making it "manual", but when forward, can you still use the focus ring, does it operate similar to Lumix lenses in that mode? Lumix lenses are nice to pull focus with hand.

 

[homerc67]

Focus is not repeatable so a follow focus will not do much good. When the ring is in the forward position it does not respond from what I remember at least, not full time override like Canon lenses offer.
