gravastar Posted September 29, 2012 Share #81 Posted September 29, 2012 Advertisement (gone after registration) .............................. Now would Leica had implemented some intelligent image stabilization into the system, this all would be very exciting, but as it is now - old tech EVF + lack of stabilization or improved (reduced) lag, this EVF is merely a gimmick solution for verifying mechanical RF/lens collimation or shooting from awkward angles with an eye level finder............................ As long as you don't want to stabilize the whole EVF image and if the Maestro processing power is sufficient a stabilized EVF solution may be possible. This could produce a small stable area within the frame which could be used for critical focusing. It's possible to shift and overlay selected areas from sequential frames to provide a stable VF image of part of the scene you are photographing. Bob.

ayewing Posted September 30, 2012 Share #82 Posted September 30, 2012 Yes stabilisation of both lens and the EVF image is quite possible as Olympus have demonstrated in the OM-D E-M5 and it offers the possibility of twice the refresh rate in the viewfinder. Admittedly this is with a micro four thirds sensor though a rather good one from Sony with 16Mpx. It makes me consider whether it is really worth upgrading from the M9 to the new M. I could stick to the M9 for wide and medium lenses and use my OM-D for the tele stuff with the advantage of the X2 crop factor. Link to post Share on other sites More sharing options...

lct Posted September 30, 2012 Share #84 Posted September 30, 2012 There's something i don't quite understand here. What's the point of expecting a "more modern" EVF for the M240 if the slow frame rate of 30 fps is not due to the EVF but to the camera itself?

stevelap Posted October 2, 2012 Share #85 Posted October 2, 2012 Well, because there is more to perceived display quality than refresh rate. E.g. Resolution. Not that many have had the opportunity to try the M with its existing EVF yet..... Link to post Share on other sites More sharing options...
lct Posted October 2, 2012 Share #86 Posted October 2, 2012 How about moving subjects? Are we supposed to remain at 30 fps with every new EVF while non-Leica ones will work at 60 or 120 fps? Link to post Share on other sites More sharing options...
gravastar Posted October 2, 2012 Share #87 Posted October 2, 2012 Advertisement (gone after registration) Well, if the processor etc. is fast enough the 30fps could be interpolated up to 60fps or more to give a display with less judder with movement of the camera or subject. Here's hoping.... I also hope the electrical interface is compatible with future EVF display improvements. Bob. Link to post Share on other sites More sharing options...
lct Posted October 2, 2012 Share #88 Posted October 2, 2012 Thank you Bob but i've been told that the limitation of 30 fps could be due to the M240's sensor itself so i wonder how we might profit from future EVF improvements from this standpoint.

The output from the sensor remains at 30fps but the software generates an intermediate frame from two consectutive (or more) sensor frames. The intermediate and original frames are then displayed sequentially to give a frame rate of 60fps. This is similar to what 120Hz TVs do by interpolating a 60 Hz frame rate. Smart software can use techniques such as motion prediction to improve the visual result. Whether the interpolation software would run in the camera or EVF we don't know - it could be either. Having an external EVF may be a blessing considering the rate of development, see Epson Ultramicon display. Bob. Link to post Share on other sites More sharing options...

In TVs it doesn't matter, but it does in a viewfinder. The interpolated 60 Hz signal would be worse than the original 30 Hz one. Link to post Share on other sites More sharing options...
250swb Posted October 2, 2012 Share #91 Posted October 2, 2012 For anybody thinking of buying the Leica branded EVF I would wait and keep reading the photo press as it may already be out of date, unless they can do a quick switcheroo. Epson have announced a considerably higher grade EVF and if things go to the usual plan the final product will follow soon, probably the Olympus VF-5.

rramesh Posted October 2, 2012 Share #92 Posted October 2, 2012 In the technology game there is no room for a company that moves like molasses. Leica has yet to ship the new M and the EVF has been superseded and the processor needs upgrading. Link to post Share on other sites More sharing options...

" The new finder will be for both internal and external use, just like the current one. Steve Link to post Share on other sites More sharing options...
stevelap Posted October 3, 2012 Share #95 Posted October 3, 2012 More views of the new panel here http://www.l-camera-forum.com/leica-forum/2192855-post80.html (Click the link) I'll certainly wait a short while before buying an EVF for the M, just in case. It would be nice to think that Leica could also use the new higher resolution Ultimicron display in their offering, but they might already be too far down the line for that in the short term.

mjh Posted October 3, 2012 Share #98 Posted October 3, 2012 The camera is 30 fps at Full HD resolution. The viewfinder is only VGA solution. Actually it is SVGA (800 x 600). The new viewfinder would be 1024 x 768, i.e. XGA, requiring about 64% more bandwith. The rear display is VGA though. Link to post Share on other sites More sharing options...

Well Sony just invested in Olympus so I wonder if future Olympus and Leica finders might use Sony panels or re-branded EVFs and not the Epson ones.

wlaidlaw Posted October 9, 2012 Share #100 Posted October 9, 2012 I did wonder, given it is probably 3 months at least before any of us have our ordered M's, that Leica might decide to use the new Epson 2.4MP screen on their EVF2. No, it's a silly idea, they will want to sell us an EVF3, with the new screen, in due course. Actually at just over £300 for the EVF, an upgrade in 18 months or so will not be too painful.
