Megapixels, Print Size, And Shutter Lag

Wed Dec 26, 2001 8:05 am

I am thinking about getting a new digital camera to replace my N90s, but have some questions about megapixels and final print size. I currently have a 2.11 megapixel digital camera, which equals 1600X1200 resolution pictures. I figure that this can make good 4X6 and 5X7 shots. I have read that a 2.11MP camera can make 8X10 shots that will look decent from behind a glass frame. But what I am wondering is how big of a print can I make from a camera that is 4MP (Canon G2) or 5MP (coolpix 5000, F707). I would appreciate any advice especially from owners of the above mentioned cameras. Also, one thing I dislike about my powershot s110 is the lag between the time when I press the shutter release button and when it actually takes the pic. This would make it a very impractical camera for takeoff and approach shots. Do the cameras I am looking at i.e. the G2, coolpix 5000, or F707 have a noticable lag. I have read reviews but most do not mention the lag time, especially with respect to taking action photos. Thanks.

I read a review in a magazine about the G2 and F707 but I can't remember which one. Maybe Amaeture Photographer. Basically, what they said was that these new models improve on the lag time of previous models, but are still not as fast as conventional cameras.

I suggest that you go and test one for yourself to find out whether the lag is acceptable or not. Try it in differnet modes etc. The size/compression settings will affect the lag time.

Hope this helps!

Sorry didnt see your original posting.

Both the G2 and the 707 are similar. I have the F707 which is great fun.

To be honest I notice NO shutter lag time. The Autofocus on the F707 is superb. 10 out of 10 to Sony. Havent had a out of focus shot yet!

I would say go for the 707 is has some neat features that the G2 dosen't.

I ditto Colin's statement. I have a new F707 and it is a superb camera. So easy to use and the quality is absolutely outstanding. Just look at some of his shots.

I got fed up with buying film, trying to use a film scanner and not ever getting the results I wanted. This Sony F707 is the best digital camaera I have seen yet (short of getting a D1X) for under a grand.

You can really do a lot with it. It has settings on it that are similar to regular film cameras, so it is really easy to use. I am looking for a good teleconverter for it.

The F707 is your camera - GO GET IT!

With regard to required megapixels ... for quality publications, a resolution of 300 dpi is considered the norm. This works out as 7.2 megapixels for an 8x10 print. Personally, I find 240 dpi the optimum res. on my Epson 890 (i.e I see no improvment at higher resolutions). This works out at 4.6 megapixels. A print a 200 dpi is, on close inspection, inferior to the 240 dpi version, but I doubt the difference could be noticed at a comfortable viewing distance. So I'd say you could get a decent 8x10 print from around 3.2 megapixels.

Having said that, the nature of a digital image combined with various photo enhancement controls in the printer driver mean you may find prints acceptable at lower resolutions - you'll need to see examples and decide what is acceptable to you.

But note that the 8x10 format maps rather poorly to the actual image size, which scales up to something more like 7x11, so if you want prints of exactly 8x10, you will have to do some cropping, so some of your pixels are gonna be wasted.

Cheers,

Colin

Hi:

I have an F100, an F70 and a Digital Coolpix 990...

I love what the digital is adding to my way of taking pictures, and when a decent but feasible digital nikon mount SLR goes to the market I will try to get one. But If I had an F90x (N90s) I wouldn't substitute it for a digital camera. Not now. Even if I had a 6MP D1X, I don't think I would retire the film equipment...

Why don't you buy the digital and keep the F90? just my opinion

Anyway you can visit http://www.dpreview.com that has, in my opinion, the best digital photography information resources...

Anybody use the Minolta D5 or D7 for aviation pictures?
D5 is 3.3mp and the D7 5.0mp so the results should be good.
