In Topic: Customer Notifications -- Gates EX1 Housing

22 April 2009 - 01:21 AM

I have just received the latest version of the adjustable viewfinder from Gates.
I can say that this is a real improvement over the original eye-piece: distortion have been solved and all in all you get a clear view and camera information are readable. Moreover you have the ability to adjust it according to your diopter needs.

Thanks to John Ellerbrok and Gates staff to have listen to customer need. I have appreciated John approach towards customer needs and opinion.

Happy Gates customer

I will give the adjustable viewfinder a try. I believe focusing will give us hassle with such a camera,... the camera viefinder itself is low res and hardly usable for proper focusing. I hate external monitors but if Gates comes out with a new full hd solution and possibly Sony will update firmware (dreams ?...) enabling peaking, zebra and DOF bar on ext. monitor, I will consider to buy it.

At the moment I found that the best solution is staying within hyperfocal range (quite restricting...); I set shutter to 1/50 so that I always get a high IRIS, use ND when needed to stay at F8 at the highest, auto IRIS, manual focus. With Fathom SWP I get proper focus on full wide; I was not able to get a proper focus with zoom in. Some close subjects (ex. a dolphin at 50 cm. from the camera) even with full wide turned out very soft, probably they were out of the hyperfocal range.

Drew: I finally convinced Sea&Sea to adapt the lens for Z1 to the A1 housing and incredibly I was right, I got sharp pictures edge to edge and near full zoom through. I have approximatley 95/100 degree compared to the monster 120 degree but quality is ok. So an happy end to the bad story finally !
Concerning progressive vs. interlaced I thought that interlaced delivers a slight better light sensitivity than progressive but I may be wrong. Concerning 24p being in a PAL world I thought I'd better stay with it rather than 30p which is more suitable for NTSC.

Mark: why don't you try to setup shutter speed to a fixed value, you may use a rather low speed shutter (1/50 for 24p or 1/60 for 30p or even shutter off for macro) so that you always get the maximum light and high IRIS value to maximize DOF; IRIS to auto (you may switch to manual if you feel you are underexposing or over exposing). I would also set gain levels to: 0, 3, 9 and toggle between them according to needs.

I got my EX1 at the end of July and just had the chance to play with it on land during a vacation in Germany/Black Forest.
I recorded only in 1080p24 HQ. Found that auto focus is too slow so manual focus is a must; on the contrary the exposure you get with auto iris is usually ok even if it may look underexposed in the lcd. Gain always to 0 even under trees shade. Picture profile is very important to get "wow colors" and I used most of the time "Philip Bloom" set but I preferred to keep details on.
White balance most of the time for daily use set in picture profile to 5200 or max 5.600 K.
Panning / fast moving objects issue at 24p: I had a manfrotto tripod with a "fluid like" head 501 all the time; panning with 24p must be very very slow otherwise you get nasty effect.

Based on 10 days experience I worked out some resolutions for the underwater video (I am placing an order with Gates):

- 1080 24p HQ mode preferred but I will also give a tri to 50i;
- Fixed speed shutter: 1/50 for 24p (I may even think to go down to shutter off as underwater world usually is quite slow);
- Auto IRIS;
- Manual Focus: I think that finding Hyperfocal should be quite easy with DOF indicator which I found very accurate and ofcourse peaking (red peaking is very evident even in the low quality viewfinder);
- Fathom lens is a must;
- No external monitor: I have always found ext. monitor of no use, plus my eyes are aging and they perform better with the viewfinder.
- White Balance: 5.600 in Picture Pofile preset, plus preset A or B at an higher level (I may even think to test the max available 10.000 to push red at depth); one push white balance stored on the remaining preset.
- Gain: Low 0, Medium 3 or 6, High 6 or 9.

EX1 is capable of stunning quality, fantastic low light / low noise performance and mounts a nice wide lens; all this considered I am quite confident I can get out of it something really better than what I am currenty getting with my A1/Sea&Sea rig.

P.S.: I am not a Macro fan/expert so I may have an easyer task
