AWB:

EM5:

  • Natural -2
  • Shadow&hilight +1-2

GH2:

  • Smooth -2+1+2
  • WB 1 blue 1 magenta

WB Sunlight setting:

  • EM5: wb: a-3 g-1
  • GH2: wb 1 magenta 4 blue

Manual WB SET mode:

  • EM5: wb a-2 g+1
  • GH2: wb 2 magenta and blue

If you have any suggestions i'd love to hear, my main goal is to match color tones.

Part II : sharp pocket anamorphic set on OM-D https://personal-view.com/talks/discussion/8668/part-ii-sharp-pocket-anamorphic-set-on-om-d Tue, 05 Nov 2013 06:19:08 +0000 sebfarges 8668@/talks/discussions Hi my anamorphic friends ! Here are some new stuff taken with my favorite light and sharp anamorphic combo. Tell me what you think ! Thanks for watching !

This movie has been shoot a week-end mid october in Bordeaux, and first week-end of november in the countryside. I'm glad to have now I think the perfect anamorphic set combination for my baby Hypergonar anamorphic lens. I bought few weeks ago a used Qioptiq C-mount lens, usually used in industry. This lens is very sharp, even at it's fastest aperture (f1.6) and this wide aperture is still usable with the anamorphic on it ! Some of the shot of the movie had been taken at f1.6.

It was not possible to screw directly the anamorphic lens on the Qioptiq prime lens because the front barrel is turning when you focusing. So I ordered a special machined flat step up ring to attach the two lens. I've unscrewed the ring on the Qioptiq that is maintening the glass, and replace with the special machined flat ring. Then I screwed on it the original small Berthiot clamp that can align the anamorphic lens. Then I put the baby Berthiot hypergonar in it. The combination suits perfectly ! The weight of this anamorphic combo is quite light. The Hypergonar weight is 57 grams, the clamp maybe 20 grams, the Qioptiq is 210 gram, then the two filters (diopter + variable ND) and step up rings maybe 150 grams. So the total is around only 400 grams ! And finally using the OM-D with it's 5 axis stabilization system with an anamorphic combo is very useful !

This movie has been shoot during thursday 18th of october 2013, from the morning to the end of the afternoon, bringing my daughter at school, then filming with my students at university, then taking my daughter from her school.

I'm glad to have now I think the perfect anamorphic set combination for my baby Hypergonar anamorphic lens. I bought few weeks ago a used Qioptiq C-mount lens, usually used in industry. This lens is very sharp, even at it's fastest aperture (f1.6) and this wide aperture is still usable with the anamorphic on it ! Some of the shot of the movie had been taken at f1.6.

Here is a movie taken with this lens alone :

Sharp C-mount LINOS MeVis-C 35mm 1.6 on Olympus OM-D E-M5 https://personal-view.com/talks/discussion/8192/sharp-c-mount-linos-mevis-c-35mm-1.6-on-olympus-om-d-e-m5 Sun, 22 Sep 2013 08:29:14 +0000 sebfarges 8192@/talks/discussions

I've found this incredible C-mount lens on Ebay for 150€. It's a LINOS MeVis-C 35mm 1.6 C-mount lens made by Qioptiq.

It's an industrial lens, usualy sold for 1090$ , http://pstechnik.de/en/optics-c-mount.php .

The 35mm is designed for 1'' sensor. It has been used in some of the shots of Slumdog Millionaire. I'm looking for a solution to use it with my anamorphic lens my baby Hypergonar. I did some fast test and it's very promising !!!!!

17mm SLR Magic T1.6 (prototype) on 5 axis stabilization OMD E-M5 https://personal-view.com/talks/discussion/7959/17mm-slr-magic-t1.6-prototype-on-5-axis-stabilization-omd-e-m5 Sat, 31 Aug 2013 10:47:24 +0000 sebfarges 7959@/talks/discussions

I've just had for few days the prototype of the upcoming SLR Magic 17mm T1.6 lens in micro 4/3 mount.

This lens reminds me the one from Voigtlander the 17mm f0.95 I test once .

Despite it's a T1.6, the SLR is a very fast lens, and I had to use strong ND filter on it to be able to use it at it's fastest speed at 1/50 shutter speed. This lens is a prototype so I can't show it, but this model looks quite like the 25mm T0.95 from SLR. It has also a no click aperture ring. Most of the shot of the movie are taken at T1.6, and you can see the very good sharpness of the lens, even at its fastest aperture.

SLR Magic told me that : "this is a SLR Magic CINE designation lens and not a HyperPrime lens so it is made for the budget indie filmmaker. It is in the same series as our 35mm T1.4 CINE II lens. Price of the production 17mm T1.6 lens is TBA (to be announced). The SLR Magic CINE 17mm T1.6 will have the same mechanical build as our 35mm T1.4 CINE II lens that repeatable focus. The 35mm T1.4 CINE II lens will be compatible with our upcoming 1.33x Anamorphic adapter but the 17mm T1.6 will not be on the compatible list. Field curvature effects causing softness at extreme when focusing at close focus distance were put into consideration during lens design and edge sharpness should be quite sharp even when wide open. Light falloff during wide open aperture is well controlled."

I have use the OMD E-M5 from Olympus. I've bought recently this camera because I was really impressed by the movie of Andrew Reid, where we can see the proficient internal 5 axis stabilization system. It was quite hard for me to use this new camera. Two main problems have appeared :

  1. I found that the contrast in classic image mode are very strong, the black are too black to my opinion (I've used the Natural mode). Then I decided to change the mode and I've used the Art filter 3 (ton neutre et lumineux, I suppose in english it's "neutral and bright tone") to have less strong blacks. But this mode gives green rendering (and the ND add it too), so I try to color corrected it. That's why you have two mode in this movie, the Art filter 3 is in the countryside and seaside shots. I did light color correction in quite all the clips.

  2. The second problem is the using of ND filter on OMD with the stabilization. At the begining of my shooting I was using a variable ND filter from Cokin. The problem is that there is slight vigneting when you are closing it. And this vigneting is moving because of the stabilization. You can see this issue in some of the shot, the traveling with the girl with the yellow bag, for example.Then I decided to use another ND filter, not a variable, the Hoya NDX400. With a constant ND filter, the problem of the "moving vigneting" disappear. But it's less easy to use. Especially with the OMD that has less efficient dynamic range than the GH3.

Anyway despite this problems I have discover with my first use of the OMD camera, I'm really impressed by its internal stabilization sytem, for example it allowed me to do these shot from the car in the small roads of north Ireland, with a third part lens such as this SLR Magic 17mm T1.6. I'm really happy using this lens, it is a good experience and it's useful to have a fast 17mm, especially when you think that 25mm is not enough wide, and 12mm too wide.

Bricked my GH1. Help on a replacement https://personal-view.com/talks/discussion/6180/bricked-my-gh1.-help-on-a-replacement Tue, 19 Feb 2013 06:36:07 +0000 ppcroft 6180@/talks/discussions Sorry if there is a similar thread, but could not find it. Apologies if this is long....

I was being stupid and tried to remove the SD card that got stuck in the card slot of the 3 year old GH1 by a little force and a pin. The camera is now dead and the Panny service center told that the main board has been damaged and need replacement. It will cost in excess of $350, but parts are not available either. There is no way I am going spend that much on a GH1 now. So I am in need of a camera and need it before 10th March before I go on vacation.

GH1 was my first serious camera and it was Vitaliy's hack that kindled this passion. I have the following lenses now:

Lumix 14-140mm Lumix 20mm Samyang 85mm MF (Nikon) Nikon 50 mm 1.8 MF Vivitar 55mm 2.8 Macro MF (Nikon)

I am a casual shooter and shoots mainly family, nature etc., especially while on holidays. I was sold out by the GH1 videos and I have almost used the camera 80% for videos. Now that is not to say I don't use it for stills. Well, stills are not so much fun with the GH1 (peace, in a more capable hands they sure can be). Of the lenses I use, I almost always use 14-140 for video and by virtue of being having AF and myself being lazy, use it for stills as well. This a not a very ideal solution. I had always wanted a quality lens that can can do AF, video etc. day/night. The MF lenses while excellent, had me working more and I always found myself missing the fun while in the middle of changing lens, adapter and doing manual focus etc.. All this combined made sure the GH1 was mainly a video camera. I often wondered changing format and going for a Nikon or Canon for stills and have some AF lenses for them. The bulk and costs kept me at bay. Where I live the m4/3 is almost unheard of. Even the Panasonic service engineer had not heard of the GH1 when I spoke to him. So Panasonic lenses may be of little resale value here. So that was another factor in looking at m4/3 solution as a replacement camera.

Having been an avid follower of these forums, I took a break for almost an year as I was trying to learn other things like Adobe CS6 etc. Now the sudden demise of GH1 made me search and there was this GH3 with almost universal praise. I hoped the GH3 would solve my problems with the still photography if were to mate it with a good AF lens like the 12-35 or 35-100 from Panny. In a moment of excitement I back-ordered a GH3 body+ battery + 2 year B&H SquareTrade warranty for about $1550. The lenses have to wait for now. However now there is a possibility that the camera may not be delivered by 10th March deadline...

It is then that I read about the Olympus OMD EM-5. I had totally missed the noise around this one. The IBIS and image quality seemed quite a match for the MF lenses that I had (was planning on a Samyang 35mm cine lens, but now the budget is gone). Video seem inferior to Gh3. I also feel it may not be comfortable to hold the body with big lenses sans the grip. The camera is available right now and cheaper and...I could not make up my mind.

So I am now looking at options as an after thought..I think I can change my order with the B&H.. I would appreciate suggestions what would be a best camera GH3, OMD EM-5 or any other. Any suggestions welcome.. Thanks in advance
