Photo Forum / Digital Photography / DSLR Cameras / September 2006What might help DSLRs, especially pro DSLRs.
Something like the Olympus E-330 has for live preview. Only instead of or in addition too, they'd have an electronic viewfinder that could "swing into" the path of the optical eye viewfinder. This would allow the mirror to be lock-up during high speed continuous shooting, allowing for much faster FPS rates, possibly in the 20-30 range, depending on the limitations of read-out speeds from the sensor or cropped sensor area. This would require a second, smaller monitor sensor, much like the E-330 has. It would also take some of the strain off the whole camera mechanism and lessen battery use. > Something like the Olympus E-330 has for live preview. The whole concept of an SLR renders the "live preview" moot. Adding live preview would do nothing but increase the cost of the camera. > Something like the Olympus E-330 has for live preview.

Get decent one and you'll get 20-30 fps... > Something like the Olympus E-330 has for live preview.

If you get 30fps then you are going to have the added problem of making sure the cache will hold 6 seconds of shooting at this rate! You are talking 180 frames! Also think of the daunting workflow dealing with so many shots. > > Something like the Olympus E-330 has for live preview.

You'd only be looking for "the" action shot, not worrying about the minutae of sharpness or detail-level of each image. >>>Something like the Olympus E-330 has for live preview.

The problem, at least with current technology, is that the pixel processing rate would be huge: 12 megapixels at 30 frames a second is 360 megapixel/second processing, including the jpeg compression for the view. That's about 4 times faster than the current fastest camera, the 1D II N. Maybe someday. Roger > Something like the Olympus E-330 has for live preview.

If you want these sort of features so much why not just buy a camcorder, 30fps of poor quality shots, will that make you happy? > > Something like the Olympus E-330 has for live preview.

Don't you Canon shills ever get tired of barking against features that will inevitably find their way even into your cameras? Dust control has arrived (whether Canon's actually works is a question) and 30fps need not be poor quality. If some sports shooter is only utilizing the centre 50% of their frame now, and Canon decides to do something to punch up the speed, the shooters will jump on it. >>>Something like the Olympus E-330 has for live preview.

The "good shooters" fill the frame. Roger >> Don't you Canon shills ever get tired of barking against features that >> will inevitably find their way even into your cameras?

Don't you ever get tired of defending your asinine fantasies? Any "sports shooter" who needed that kind of speed could grab any decent digicam and get both an electronic viewfinder (no mirror lockup necessary) and 15+fps. The professional shooter would grab the right tool for the job: a video camera. What I found most interesting and odd is your assumption or assertion that your fantasy contraption would "lessen battery use." How? It not only has an electronic viewfinder with a "swing into" mechanism, whateverthellthatis, it also has an additional monitor sensor; and it has to process the flood of images.

Which one to denigrate first? > Gee, one retard said video was no good, another was supporting it. YOU, of all people, calling someone a retard?

I wasn't supporting using a video camera for still images; I was pointing out that the camera your need-for-speed fantasy "sports shooter" needs already exists. Oh, and AUK is over there, bonehead.

What does seem to be Rich's game, though, is to start flames or at least heated controversey. He does this in a number of ways, which are observable over a short time span. Why he does this, no one can say. Sometimes he's brilliant, but frequently creates a lot of bg noise.

His mommy and daddy didn't pay attention to him unless he misbehaived, so he craves attention, and that's the only way he knows how to get it. > >>> If you want these sort of features so much why not just buy a camcorder, > >>> 30fps of poor quality shots, will that make you happy?

Flames are not started by posters posting things about DSLRs, they are started by people taking taking things personally and reacting. >> What does seem to be Rich's game, though, is to start flames or at least >> heated controversey.

Pot, Kettle, Black! Pot, kettle, black, though, is better grammatically. Signaturelsmft >> > Something like the Olympus E-330 has for live preview.

Canon shill? Dickhead! No I take that back, STUPID DICKHEAD! > Something like the Olympus E-330 has for live preview.

Always seemed a worthy approach and it would be a more elegant way to get your unblocked viewfinder and low battery consumption. Sensors have improved a lot since the E20 so a current implementation of this design would be a 'killer app'. -Guy |
