Olympus EM-5 topic

Did you hear any noise from the body when recording video with 20.7?

If IBIS works, it would generate humming noise. Otherwise it might be IS based on software just like all other m43 bodies from Olympus.

Alex

if IBIS works, there is zero wiggle visible. Its day and night.

Olympus sells an adapter for old OM lenses that has a chip build in (MMF-2 UM), kinda like those focus confirm chips in canon adapters. I think that chip makes the difference ...

stoney

BTW how did you confirm IBIS works for 20.7?

Also did you try 43 lenses?

stoney

Does IBIS work for taking photo with vintage lens?

Hopefully there's a menu item that enables IBIS for recording video with non-electronic-m43 lens.

Alex

well, still no IBIS without a electronic m43 lens WTF. Tried the Pana 20mm F1.7. and here the IBIS works as well. With the 20mm the IBIS is like a running-without-moving nightmare. Very delayed purpose motion ...

Could be this way to force you to buy m43 lenses.

BIG SHIT: no IS when using an adapter!!

this morning I mounted the Canon FD 135mm F2.5 to the OM-D and there was zero effect from the IBIS. checked the settings, was set to is1.

Next I mounted the Panasonic 14-140mm, turned its own OIS off and - voila, bellyful 5-achsis IBIS.

I need to figure that out now. Maybe there is something like "shoot without lens" buried in the menus some where.

I only had the camera set to video mode by now. When I switch it on, here is no noise. The noise starts when I access the main menu! Strange.

There is one way to find out for sure. Attach SLR lens with an adapter. While recording video, detach the lens from the adapter. See if the sensor is dancing or not ;)

People complained about humming noise from E-M5. Olympus said it's from IBIS operation. There is no noise while recording video.

Who wanna find out about it?

This video shows how much the sensor moves when the half shutter is pressed for taking photo. But sound seems muted.

stoney

Did you use a telephoto lens like 135mm at shutter speed around 1/60?

It'll be difficult to tell when using a wide angle at fast shutter speed.

Frankly I will be surprised if IBIS works during video recording.

video clips I've seen of IS in action have been very impressive, and not subject to the strange contortions you normally get with software IS.

on further research I am positive video mode still uses IBIS, as someone has the upside IBIS issue on thier video clip

stoney

Like all other Olympus bodies, I guess no IBIS for video recording. Just software stabilization.

@vitaliy that makes sens!

from the manual page 67:

"If [Image Stabilizer] is activated while recording a movie, the recorded image is enlarged slightly. Even if [Vertical IS] or [Horizontal IS] is selected, the setting for [Auto] is applied."

the OM-D's build quality is much better than that of the GH2. The Problem is that the camera is a bit smaller than the GH2 and there is not much real estate left for all the tiny buttons. The thumb and index finger wheels on the right top are very well place and nice to operate. I couldn't find the function to zoom in to get the focus right. Must be there though.

@Alex

It is very interesting camera, hope to see more information from you soon.

As for sensor crop, most probably it is same as normal 43 sensor crop, GH2 has oversized sensor, so in 16:9 modes crop is smaller.

just pick up the Olympus MO-D E-M5 and charged the Battery half way through. Now I need to learn how to best setup this camera for shooting video. Flat image with high dynamic range is what I'm after. There are a lot of shooting modes to figure out. I chose one that sounded flat, contras -2, sharpness 0, saturation 0. The OM-D has a very cool gamma curve function where you can shape an "S" or an "?" (flipped S). I went with the "?" to brighten up the lows and bring down the highs for more DR.

I have two Olympus OM 28mm 3.5 lenses so I can mount the MO-D on top of may GH2 and shoot with equal lenses, equal ISO and so on ... the first try was very rushed and hand held. I will need some time to learn the OM-D better and to carefully set everything up.

First finding that caught me by surprise is that the OM-D has a larger crop factor than the GH2. It might be the IS that causes a slight zoom in on the censor (I read something about it in the manual) ... Compression artifacts on the OM-D are terrible. The GH2 is patched with Sedna AQ1. Focus on both lenses had been set to infinity.

Colors and DR are very very promising on the OM-D.

@ zigizigi I already asked Olympus about 25P when E-P3 came out. I got an answer from Japanese department in bad English:

"We could find the specification for FullHD format in PAL and NTSC market.

And Full HD format has a many kind of frame rate option. In europa, basic frame rate is 25i or p and 50 i or P, but all product can hundle option frame rate which is 30i or p and 60 i or p. And also NTSC area, plyer also has same function.

Therefore we can offer all customer for AVCHD 60i mode of E-P3. "

So basically they are saying, your TV can handle those files, even if you are in PAL region, so no problem. Same goes for Nikon 1 and Samsung mirrorless. It is true that consumers that specifically look for 25P and 24P is very small, and most people couldn't care less.

Alex

well, for some reason I pre-ordered the E-M5 back in January. Before I'll send it back, I would like to do some side by side tests with the GH2 to put the EM5's IS and DR in relation.

major fails of E-M5 's video mode:

low bit rate
no 24/25 fps
no audio meter/control
no video recording while HDMI is plugged in

how ever, the in body 5-achsis IS and the (maybe) high dynamic range makes it an option for some sneaky documentary work. Can't wait to test my Canon FD 135mm lens hand held with the in body IS ...

Good idea zigizigi- if Olympus knows people are seriously interested in the video they might take it a bit more seriously. More frame rates, better bit rate, etc.

zigizigi

I know it might sound naive but I could not resist from dropping a line to Olympus requesting 25p (I'm PAL and don't care much about 24p).

niu

isn't it possible that 24p and/or better bit rates come with a future firmware upgrade? The GH1/2 without Vitaliys hack is also not "so" good...

hedrox

It would be very interesting to test this camera on a quadro/hexacopter .. I would like to know how much smoother would be those shots with that nice 5axis IBIS...

tim46

I just watched a video where it was mentioned Olympus will be coming out with a less expensive OMD model later this year, one without the weather sealing. Perhaps Olympus will improve the video capabilities on the next model, giving people the option of 24p.

tim46

As impressed as I am with some of the hacked GH2 footage I think my next camera will be an Olympus instead. Probably not the E-M5, I'll wait for that 5 axis IS to filter down into a less expensive E-PL3 or E-PM2. The huge draw for me is that the handheld footage will look smooth without having to add something big and expensive like a Steadicam. The drop in price of the GH2 is very tempting but that new Olympus image stabilization is just too good.

zigizigi

Here comes THE MUD! Look at 0:22 quick pan and consider 20Mbit limit. GH1 waves hello back from 2009!

And I have nearly fallen in love with this camera. Another example of marketologists brutally castrating the genious work of engineers.

Howdy, Stranger!
