I wonder how much longer we are going to have to wait till we see an all in one solution for our application. By that I mean, a camera that will shoot HD video and capture high resolution stills (at an acceptable frame rate) at the same time. I hope it's soon!

Hot of the press(release), the Canon 7D. Here and Here.

Looks and sounds promising but I'm not trading in my 5D just yet.

So if I am understanding this correctly, is this supposed to be a sort of mid-point between the digital rebel series and the 5D?

EDIT: Oh never mind. This will be useless for skydivers. No sports mode on the dial!

There's a dedicated switch to flip from shooting stills to video that encircles a start/stop button for recording, so it's much easier to get right to shooting video than the 5D.

Uncle Lou,
Would you get me one for Christmas????
PLEASE?????

and has better controls but it's not a full frame.
The 5D mkII is full frame but shoots 30p only...
I can't wait to see in the camera in the future with full frame sensor and 1080 24p capability.

BTW. What exactly would make FF better ?

Full frame sensor = less pixel density = far better effective resolution

But 18 MP?? On an APS-C sized sensor??

That's almost ridiculous. Not even the sharpest L-series lens will deliver that kind of resolution.

BTW. What exactly would make FF better ?

How is that? The advantage of less pixel density is less noise. More pixel density gives higher resolution. This is the big advantage of a cropped sensor over a full frame sensor. Given the same lens and the same number of pixels, the cropped sensor will have more pixels per square inch of the picture, giving it a higher apparent resolution.

More pixel density gives higher resolution.

An 18 mp image from a cropped camera is not the same as a 1.6 crop from an 18 mp full frame camera. The cropped camera picture will have higher resolution.

Well... Full frame sensor = less pixel density = far better effective resolution

18 megapixels is 18 megapixels regardless of the sensor size

An 18 MP full-frame sensor will give you a sharper image than an 18 MP APS-C sensor.

This is only due to the fact that on the APS-C sensor, some of the 18 MP will be lost due to a lack of optical resolution (sharpness).

Yes... In terms of sensor resolution .... But the word "resolution" may also relate to optical sharpness.

Acoording to this even the non-L zoom lens 17-55 2.8 will deliver 2536 LPPM

The test you are referreing to is using the unit of LW/PH (Line widths per picture height)

In order to utilize the 18 MP of the EOS 7D, the optics would need a resolution of 3456 LW/PH, equal to the vertical number of pixels on the sensor.

... the maximum MTF value is measured 2126,5 LW/PH even though the theoretical maximum would be 2304 on that sensor...

and another problem of so many pixels will be light difraction

with apertures of 11 and upper, the diffraction cone will be bigger than the pixel size, so it does not care how good the lense is, it is fisically impossible to get more resolution...

Its a rare time that you are using a camera and your thought is "Damn, this camera is too powerful for my uses"

I see this one being popular once prices fall to the levels that the 50D is at now. Its also going to require an investment in L glass to get the most bang for the photos. Then again at 2K for the body what is another couple of hundred for the 17-55?

I remember after the 5Dm2 came out and I thought it was pretty cool and exiting, people were laughing at me in here for thinking so...

Just curious, why 720/50fps?
Do you have IS on your 18-55? If so, did you turn it on?

24p, 25p, 30p, and 50i are all poor siource framerates for slomo by comparison to 60i and 60p.
Very difficult to create more interpolated frames where there were none to begin with, and call it "good."
Umderstanding apertures, zoom depth, etc will really help you with image quality more than a different lens will.
try shooting everything at f5.6 or f8. You'll have little to kno shallow DOF, but you'll minimize blur. Shutterspeed and aperture will determine blurs, framerates will determine smoothness.

it does get very hot. "Extremely" isn't the word I'd use. If one isn't familiar with file-based camcorders, it probably would be considered "extreme." Tne EX1/EX3 get equally hot...lots of memory buffering, lotsa heat being generated.

Is the shutter tripping for each frame, or is it electronically segmenting individual frames? I would think (if the former) that the shutter motor would get hot pretty fast...

DSLR cameras don't have shutters.

CPU/transfer bus are what get hot. Most of the file-based camcorders have some heat issues of one sort or another.

DSLR cameras don't have shutters.

DSLR's do have shutters. They're not necessary, but are indeed part of the camera. Perhaps you are thinking of the leaf shutter, as opposed to the plane shutter? DSLR's don't have leaf shutters.

Okay, my apologies. I'll crawl back under my rock now.

Sorry, Bob - I should have thrown a couple smileys in my post, above.

I did not take your post negatively at all. No need to apologize.

I am embarrassed that I spoke about something that I did not know about. I WAS referring to the leaf shutter DSE mentioned. I didn't know there was another item in there that could be described as a shutter.

Bob

The shutter in dSLRs do two things:

1. Time the exposure.

2. Exclude light from the sensor during non-capture times (which is MOST of the time).

The first one is the simpler of the two...let's start there. Yes, it would be easy to substitute an electronic shutter. However, most dSLR sensors don't have that capability at this time. And there are small issues with electronic shutters. There are many ways to do it. The cheap ways have problems. Google "rolling electronic shutter" and read. Most P&S cameras have a rolling shutter. Quality concious dSLR buyers will not like this method.

That leaves the more expensive "global" or "frame" shutter. It is more expensive because it requires an additional transistor at each photosite. That may sound trivial, but if a normal CMOS photosite has 2 transistors, that is a 50% increase in transistors. Even worse, it increases the non-photosensitive area at each photosite by about 50%. That negatively impacts light-gathering capability and this increases noise. Then there is the patent position. Companies like Kodak have a massive patent portfolio. Some of these patents cover various ways to implement "global" shutters! Perhaps Japan, Inc. is simply waiting until these patents expire?

The second reason re blocking light from the sensor is probably more germaine.

ALL cameras, even P&S types, have a "shutter" to block light from the sensor. This is required because if light is continuously shining on the sensor, all the data would have to be transferred SIMULTANEOUSLY. Most sensors transfer data serially. To keep the photosites from continuing to accumulate photons, cameras close the shutter during the period when data is being transfered. A sensor with a "global" electronic shutter helps, but all Silicon areas that are un-masked generate electrons when photons hit them. These "free" electrons can decrease the signal-to-noise ratio.

Panasonic has joined Olympus in offering a mirror-less, viewfinder-less interchangeable-lens camera with the big Micro Four Thirds sensor. The 12.1 megapixel sensor in the Lumix GF1 is the same one found in Panasonic’s tiny “DSLR” style G1.

The main differences between this and the Olympus EP-1 Pen are the looks (plain, black or colored aluminum instead of fancy faux-leather), a pop-up flash (the Olympus has none), size (the Panasonic is “artistically flat”). Other standard features include image stabilization, face detection and HD video recording and ISO of up to 3200.
