Camera question

AO's photographers,

A quick question, please

Flicking through a magazine, I saw a news story about the Leica X2. By jimny it looks good, but as much as I like taking pics with my point and shoot camera, I think a Leica's too much of a specialist tool for me - (and the price is a bit relative to my skills!)

Anyway, one thing confuses me; the specs say the camera has 'no digital zoom, optical zoom x1, and a manual focus'. Does an optical zoom replace a digital zoom, or can you simply not zoom in with this camera?

(apols if this is a dumb ar5e question - it's been a long time since photography lessons at college )

cheers

Sometimes in the darkest hour, love comes shining through.
Then it doesn't seem so far from me to you.

It has a fixed focal length lens which, as you suspected, means
it has no zoom.

Is it true that a camera with anything more than 10 megapixels is a waste of time because
the human eye cannot detect any difference

If so what is the next best spec to look for (apart from price) ...
The cider gypsies have taken my camera (14mp) so not sure whether to stick with my
8mp smart phone or get a proper camera again ...

It depends what you intend to do with the images.
If you are likely to only view them on your computer
screen or print them to no bigger than A4 then it is
overkill to go much bigger than 6mp really.

But you know that marketing people are good at
hooking us into buying more than we need

If you are likely to go for bigger prints then it may
be 'really' worth going for more pixels

However, one advantage of more pixels is the increased
sensitivity at low light levels. So if you want to take
pics of your knob at night under the quilt then go for
the most you can ........... and a big zoom

As mentioned I think it depends on what you wish to do with said 'print'. However don't forget quality of glass is also important too

Like the others have said, it depends on how big you want to enlarge the picture.

However a high megapixel sensor with a poor lens isn't much good, hence why camera phones generally take poor images.

Also it depends on the camera sensor size. If you have a small sensor camera like a Bridge or compact you really don't want to go much above 10MP, the pixels get smaller and smaller the more of them there are, which results in worse sensitivity to light and more image noise.

On an SLR with a larger sensor you can get away with more pixels because each one is still going to be pretty big.

This is a good site.

Like symon says megapixels is largely irrelevant, its the size of the sensor that dictates image quality, in most compacts and slr-like cameras the ccd is relatively small, so this is the limiting factor.

Pixel size is an oversimplification, the pixels are the same size its just that there are more of them packed into the same area. This is where resolution comes in, decent cameras will output around 300dpi which makes for very good print output. Ufonrtunately a lot of cameras have poor onboard processing which can introduce aberations called artifacts due to the compression used. When i shoot with my big camera, always shoot in raw so that the information i have to work with is exactly is it came off the sensor.

The human eye is a fabulous thing you have to get up to incredible levels of resolution to match it.

I had a TZ10 a while back, and sold it.. Which I later regretted.

Managed to replace it with a TZ8 the other week. Brand spanking new from Argos outlet for 100

Excellent bit of kit for a compact.

G - the last time you came to AO for camera advice, you didn't even have the courtesy to let us know what you eventually bought or post any sample photos

Panasonic sell cameras with lenses that they make under
licence from Leica but not made by Leica. They are allowed
to use the Leica name on these cameras which is a nice
marketing ploy to make people believe they have a Leica
lens on their camera

Well they are still really good, so I don't see it mattering too much. A compact camera with a small sensor isn't going to push the limits of a lens too much anyway..

Leica also sell Panasonic cameras, with their own name, covers and inflated price tag on them.

A valid question, worth highlighting to show you one of the great " marketing scams" of camera manufacturers. Optical zoom is the number of times the image is multiplied by the lens, a high optical zoom number is normally good. Digital zoom is the image processing software in the camera doing exactly the same as you do when you zoom in on an image on your computer screen, a high number here leads to loss of image quality very quickly. In essence,10x zoom can be good, if it's opticalx5 and digitalx2, not so good if the numbers are reversed.

Pixel count? the new Nikon D800 can produce raw image files in the 75 Megapixel range, fine but you need a new hard drive each week to hold the files and, speaking from experience, at that resolution, the model tends not to be impressed when you can zoom in and show a crystal clear image of a pore on the side of her nose or the eye bogey that she didn't wipe away before the shoot

Too complicated and technical for me so will stick with the phone for now...

Had some cracking pics and videos off it so far but they only look good when viewed on
the phone...A 7 year old laptop just can't cut it these days

I have a TZ9, which is great in good light, but I've found the performance in low light conditions a bit disappointing. The pictures come out rather grainy and washed out.

Being a photography dunce, I mainly keep it on iAuto, but even in the pre-set night settings the pics aren't much better.

Is this also your experience, or is there anything I can do to improve this?

hello stranger!

how the devil are you? long time no speak. how's tricks? Are you going to pop in and see us a bit more regularly?

Crumbs, that's an old post! I didn't buy a camera until 2007, my trusty little Canon Ixus. For point and shoot, it's fine

Stick it in manual mode, restrict the auto ISO to 400 and you won't get photos that are too grainy. The camera will select a slower shutter so you will need to make sure you hold it steady.

I think All CCD equipped compacts struggle at ISO levels over around 400. The later Backside illuminated CMOS sensor compacts are much better in low light, but the ones I have seen produce inferior images in good light.

In good light the images produced by the TZ8 arn't far off those from my Nikon SLR

Thanks for the tip - I'll give it a go

Hello G - good to see you again . Hope all's well in your little world

Hoping to pop in every now and then, just to make sure you guys are behaving

I changed jobs back in 2008, to one where I actually had to work for a living - which is why I pretty much stopped posting.

Hopefully, I can find a work-post balance in life now

When I say manual mode I mean the P setting by the way, which is and auto mode but with customisable settings.

In the P setting you can also change the contrast, noise reduction, sharpness, and colour saturation of your images.

The TZ9 had a fully manual mode (M) where you can control aperture and shutter speed. Personally I don't bother, as I have an SLR if I want to mess about with stuff like that.

Oops! Cheers - I was going to use the M setting (and would probably end up very confused indeed! )



I've always said I wanted to learn how to take proper photos, but never got round to it. It seemed pointless learning the technical skills when I'm not convinced I have a good enough "eye".

I see what I think might be a great potential picture, but I never seem to be able to capture the right moment or get the framing right etc.

There may be others with large sensors (i.e. > 4/3), but these will be a few quid less than the Leica:
Fujifilm FinePix X100: Digital Photography Review
Fujifilm X-Pro1: Digital Photography Review
Sony ***** NEX-F3: Digital Photography Review
Canon PowerShot G1 X: Digital Photography Review

For lens quality, fixed focal length is better than zoom. For the body, bigger sensor is better than more pixels. A full frame 4Mp sensor will give better images than an 8Mp phone, if you're blowing them up.

Saying that, I recently entered 4 photos in a competition, 3 taken on high end gear (7D/5DII) the other taken on an iPhone. Of the multitude of entries, the winner was the one taken on my iPhone.
The pro photographer who judged the contest saw me with my 5DII over my shoulder and asked me what settings I'd used, what lens, etc. When I told her it was taken with my phone, she was shocked.

My comments are just my words - it's your mind that finds the meaning you want to find.
