Hmmmm.

Oh well, we have members from the states and canada...

This is possibly a very stupid question -
LCD display or Viewfinder?? Whats best to use when taking photos?

Depends on the camera and the circumstance.

Take a 40d for instance.
I use my viewfinder for everything except certain macro shots when I really want a very sharp point of focus.

For general stuff the viewfinder is the best still.

Viewfinder by far the best

Dose anyone use the LCD to frame pics. when you can’t get your eye to the viewfinder, when shooting forward from a car window for example?

My Cam. doesn’t have this facility.

I don't, my cameras don't have the function either. It also depends on how much of the actual view you get.
But using the viewfinder gives you more information, like shutterspeed, aperture, + or - exposure, which focussingpoint is being used, and so on. I would like to be able to see that..

A bit of news from the 2 largest brands:

Nikon announced the D90.
It has the 12,3-megapixel cmos-sensor from the D300, and can make 640x424 or 320x216 pixels, 24 frames per second movies....
Iso 200-3200, with boost to 6400, but that introduces a lot of noise.

Canon announced the 50D a link
15,1 megapixels, iso 3200, with boost to 12800 (noise?), auto iso, Digic IV-processor 6,3 in burst-mode and a 3 inch screen with 920.000 pixels.

The 18-200mm f/3.5-5.6 IS superzoom was also announced, 699 dollar...

I’ve just been looking up the specifications of the new Canon 50D.

15.1 Meg.pix. from a C size sensor!

Here’s a devilish one for any insomniac, technical / mathematical forumites to have a go at.

I’m afraid I gave up trying to work it out!

My 30D with 8 Meg.pix. has a C size sensor giving a 1.6 crop factor, [increase in lens reach, 300mm becomes as a 480mm would be with a full size sensor].

IF, and it is still a big IF, the noise levels etc. of the 50D have been kept the same as the 30D, or better. That would give an effective increase in the lens reach for the same number of megapix, ie. you could crop the photo more and get the same IQ!!

What would the new “effective crop factor” be??

Don’t be too worried about getting it wrong as I’ve no idea what the correct answer is!!!!!!!!

Hello there,

I notice from the time of your posting that the problem has kept YOU up til well past midnight! Hopefully what follows will stimulate some debate and liven things up perhaps.You raise an interesting issue. While the Field of View would be the same on both cameras the image quality (using the same lens and all other variables being equal) should be around 90 percent better (in theory) on the 50D due to the more dense pixels. In practice, I have read, things are a little different and personal experimentation appears to support this. I have a 10mp Olympus E-510 DSLR and use the standard kit lens 40-150mm with an add-on 2x multiplier (on front of lens) when in Kruger. Because of the "Four Thirds system" 2x multiplication (crop) factor relative to a full frame 35mm camera this results in a 600mm equivalent lens. Where this matter gets interesting is for the average person's need (I never print larger than A4 size) it's the lens quality that has greatest influence on the IQ. You only have to look at the prices of "Professional" lenses to appreciate there has to be a lot of truth in that. In reality a 5mp camera is capable of producing very acceptable A4 prints and for general purposes nothing more is necessary.
If however I wanted to significantly enlarge small portions of two identical images, one exposed on a 5mp camera and the other on the 15mp 50D (again using the same lens) the resultant images printed at A4 size should be noticeably different. But what if the printer is not up to scratch?
Looking forward to other viewpoints!

Released today: firmware for the EOS 450D.


Mind you, do check the firmware for your camera on a regular basis, some significant changes could be made in it, making you happier with your camera...

The Canon EOS 5D MKII has been released....

DPrevies played with it....

Just stumbled onto a conversation on a Dutch forum....
One of the guys is filming with his EOS 40D... 720x214 @ 30fps, which is resampled to 320x214, so not quite HD quality, but still...

A sample can be found here: link

Please help. Canon Power Shot S2. I have tried to find out how to do this online but to no avail. All I want to know is how do I get the date and time to appear on my pics

I'll find out tomorrow for you, bit hard to do with my phone...

Thanks DQ
