gyoung Posted July 13, 2009 Share #61 Posted July 13, 2009 Advertisement (gone after registration) Where do you get this 1/4 to 1/8th second figure? I haven't used a G-1 but the reviews I read said that when pre-focused the lag time was very brief. Imaging Resources writes - "Prefocus shutter lag is blazing fast, at 0.084 second." I'll have to try one to judge for myself but in any case the G-1 and GH-1 just represent the earliest EVIL models that are targeted to compete with consumer DSLRs not at pro models. If there is a delay between the EVF's live view and the subject, that is ok as long as you are looking through the EVF when pressing the shutter release rather than directly at the subject. I understand that fast continuous shooting is a problem as there will be no display. So I'm not sure how that can be resolved. Perhaps high speed shooting will require short bursts of very hi-res video from which you will later extract individual frames.

If you pan the camera the refresh rate of the EVF cannot kleep up with your movement so image judders. In practice I didn't find it a real problem although not as nice as an optical finder. I might put my VIOOH on it next time....... Gerry Link to post Share on other sites More sharing options...

And I know this gets worse the lower the light. The lag time I'm thinking of is the difference in time between what is displayed on the EVF and what is captured by the sensor when you press the shutter release.

The lag time I'm thinking of is the difference in time between what is displayed on the EVF and what is captured by the sensor when you press the shutter release. As far as I can remember there was no significant lag time, I think most decent digital cameras are OK in that respect now, only Point&Shoots and camera phones are a problem. Even my wifes cheap Canon is pretty good. Gerry Link to post Share on other sites More sharing options...
hamey Posted July 14, 2009 Share #64 Posted July 14, 2009 Leica R digital solution will be some discount back from Leica providing you buy the S or Swan song model of course proof of purchess required of your R or Redundant equipment, the more equipment you have the bigger discount you get. You hope......... Lol. Cheers. Ps..... sorry no discount for M users. Link to post Share on other sites More sharing options...
rick_dykstra Posted July 14, 2009 Share #65 Posted July 14, 2009 Here's a possibility. - Take a full frame 35mm digital camera (Canon 5D, 5DMkII, Sony A900 or a Nikon D3x if you're rich). - Take out the sensor and mount it in the film gate of your second favorite Leica. Use chewing gum, glue or screws according to your personal standards. - Re-connect the sensor to the donor body with extended wiring. - Gaffa tape the donor to the bottom of your Leica. Turn it on, set it to bulb and press the shutter. - Take a picture with your Leica. - Stop the bulb shot on the donor and look at the results on the screen. According to popular myth, half of us Leica users are retired surgeons and the other half CEOs of engineering firms. Between us, this should be easy.

j_lir Posted July 15, 2009 Share #66 Posted July 15, 2009 i'm just biting the bullet to get into the SLR market. i'm after a D3 now that leica has nullified the R10. Bummer, but i'll be after some R glass, such as the 50 1.4, the 80 1.4 the 35 1.4 and the 90 2, and the 180 summicron, probably a 1.4x and 2x as well. anyone want to help me out? thanks!

thrid Posted July 15, 2009 Share #67 Posted July 15, 2009 Advertisement (gone after registration) I tested a G1 by shooting one. The camera itself is very fast and responsive. AF is fast, shutter release is very crisp with no noticeable lag etc. The problem is the EVIL, because the viewfinder and capture are out of sync. There is a lag of about 1/8th of a second, which is a lot. This is not the same as shutter lag. One test involved trying to to capture a shot of a pedestrian at the exact moment when they passed a lamppost. I discovered that there was a lag of about 1/4 to 1/8th of a second between what I was seeing in the viewfinder and what was actually being captured. In every picture the pedestrian had already moved one step past the lamppost. This did not correlate to what I was seeing in the viewfinder and thought I was capturing. With any of my Leicas or Nikons (digital or analog) this would have been a simple shot to make. I also noticed juddering, when panning or tilting too fast, making grab shots awkward or impossible, And again the problem of the viewfinder and capture being out of sync. What you are seeing in the viewfinder is already in the past. Also tried to nail a test subject jumping off a park bench, jumping in the air etc. Same problem.

thrid Posted July 15, 2009 Share #68 Posted July 15, 2009 Exactly right. I'm an engineer. To me "impossible" means "we haven't learned how to do it yet". We already know what the solution is. It's called an optical viewfinder. ;-) Link to post Share on other sites More sharing options...

rick_dykstra Posted July 16, 2009 Share #72 Posted July 16, 2009 Today I had a good chat with an engineer at the Australian distributor for Prosiica industrial/scientific cameras. I'll repost the pic below so you can see which one I'm talking about. Prosilica - GE4900 - 16 Megapixel CCD camera 3 fps The GE4900C could well be an effective (though expensive) solution for R lens based digital imaging. This small camera has a Kodak 16MP full frame sensor and could be fitted with an R bayonet mount. It would connect by Gigabit ethernet to a laptop or desktop computer. It would need 12V power from a small lead acid battery, the kind I use to power my infra-red trigger set-up. It can operate in a fast frame rate mode with lower resolution, around 10 frames per second, for composition and focussing. The computer would be the electronic viewfinder. Press a key to switch to 3 frames per second at full res. Choose the shot you like best later. Because it has an electronic shutter, by means of the design of the interline CCD sensor, it has no moving parts and makes no noise. A small relay screen could be mounted on or underneath the camera, perhaps in a dark box, with viewfinder optics. Hmm ... interesting. A 5D MkII might be a little easier to work with though. And on the pocket. RRP for the GE4900C is over $12,000 USD. Welcome, dear visitor!
