  1. A typical DSLR sensor has a surface area 8 times larger than that of a compact camera. Each pixel is therefore much larger, captures more photos in a given time, and therefore has a much better signal to noise ratio.

     

    The result is a much less noisy image. That's why DLSRs happily go up to at least 1600 ISO, whereas compacts go up to 400 whilst displaying hideous amounts of noise.

  2. Hi,

     

    You should leave the working space as Adobe RBG. Photoshop CS uses the default Windows monitor profile when converting from the working space to the monitor in order to display your pictures.

     

    Assuming that the Photocal package set your new monitor profile to be the Windows default, you should be all set. To check that, right click on the windows backdrop and choose properties. The colour management setting are there somewhere (can't remember off the top of my head in which tab you'll find them).

  3. Hi all,

     

    Thanks for your answers, you've helped me to clear my thoughts a little.

     

    For the moment I'm now heading along the lines of the Sigma 12-24, Canon 24-70 and Canon 70-200/2.8 IS.

     

    The Sigma seems to be the only good wide angle choice open to me. It's not as fast as I'd have liked, but then as pointed out that isn't so important for a wide angle lens. The reviews are generally very good, and the shear fact that they've managed to make a 12-24 full frame zoom is a stunning acheivement. The fact that it's full frame means that it'll move with me (possibly after reprogramming!), unlike the Canon 10-22 which is EF-S and not massively fast either (although admittely faster than the Sigma). By the time I'll be able to afford the Sigma the 10-22 will be well tested, so I can change my mind at that point.

     

    For the moment though, I know that the 24-70 is a very good base choice around which it's possible to invest in very good complementary lenses at both ends of the scale.

  4. Hi Steve,

     

    Thanks for your response. I suppose what annoys me is that idea of spending a large amount of money on the 16-35 know that I already have the 24-35 part. However, your point is a valid one and I may well appreciate the overlap. On the other hand 16mm isn't all that wide on my current camera.

     

    You're observation regarding the 24-70 is a good one. I too believe that It's better sticking to this choice based on my typical photography. However I do like to attack wide angles from time-to-time, hence the dialema.

     

    It's probably also true that there's less need for f2.8 on a wide angle lens. What I'd really like is a faster Canon equivalent of the Sigma 12-24.

  5. Hi all,

     

    I've spent a couple of months deciding on the best lens upgrade path

    to suit my needs. I currently have a 300D which I bought with the

    kits lens to tide me over, and a 70-300 that I already owned. I went

    for the 300D over the 10D because, financially, I thought it better

    to put my money into the lenses rather than the body.

     

    The more I researched the currently available lenses, the more I

    realised that I'd rather play the waiting game and save for quality

    glass than be disappointed with the lower end zooms. I know that

    I'll get a lot more pleasure from the f2.8 and the sharp images, even

    if it takes (much) longer to build up my collection. My original plan

    to start with a 23-135 is well out the window.

     

    Another aspect that I'm bearing in mind is the fact that I can't see

    myself staying with a 1.6 crop forever. I'd rather wait for the 1.3

    or full frame cameras to drop in price, I personally believe that

    this will happen, so I'd rather buy lenses with this in mind.

     

    Besides, it means that I can use them on my film body should the need

    ever arise (which it hasn't so far).

     

    I considered going for a combination of the 16-35, 50mm/1.8 and the

    70-200/2.8, but I feel that for the type of photography I do I'll be

    switching lenses all the time. I'll be better off with the 24-70 as

    a base lens. Besides, the 16-35 has had very variable reviews and

    most reviewers seem to agree that the 24-70 is much better.

     

    So, with the above in mind I'm pretty much decided on the 24-70/2.8L

    as a starting point and the 70-200/2.8 for the telephoto end. I

    think. The hitch in my plan is finding the right wide angle lense to

    complement this choice. I like wide angle shots, and I'll certainly

    miss the wide angle end of the 24-70 with the 1.6 crop factor. Of

    the possible choices:

     

    The 16-35 it's obviously not well positioned due to the large overlap

    of focal lengths.

     

    The 10-22 is EF-S only (a real shame).

     

    The Canon 14mm prime is hideously expensive, and suffers from CA.

     

    The Sigma 12-24, while promising, is a slow lens. I'd really like to

    keep to at least 2.8.

     

    Are there any other possibilities that I'm missing?

     

    I suppose that my need for wider angles than 24mm will decrease when

    I change bodies, but I can't see that happening for a good while yet.

    Besides, if I get a wide angle that works well on the 300D, when

    changing the body for a lower crop factor becomes feasible I'll have

    a very wide angle lens, which'll be nice :)

     

    Are there any experienced wide angle lovers out there that can offer

    me some advice. I starting to question the validity of the 24-70mm

    choice due to the lack of wide angle choices.

  6. Hi,

     

    I realise that this has been asked before, but I feel that since no

    action is being taken more voices need to be heard.

     

    I would be really useful to be able to review the top photos by

    category, and, in particular by filtering on the manipulation

    statement.

     

    I know that I'm not the only one fed up of scouring through all the

    results to find the 10% of photos that aren't heavily manipulated.

    Surely it's not a big thing to ask or a hard thing to do?

  7. Hi,

     

     

    I think I'm suffering the same decision problems as many other people

    at the moment. If any more experienced photographers can give me some

    good advice I'd be appreciative. I may have missed various important

    points.

     

    I currently have a 300D with the 18-55mm kit lens and a 75-300mm USM.

     

     

    I find the 18-55mm quite irritating. The image quality isn't the best

    and it never has enough zoom; I find myself constantly swapping

    lenses. I've therefore made the decision to be a good all round lens,

    with the intention of needing to swap less often. These are the lens

    choices I've considered:

     

    Canon 28-135 USM IS - I really like this lens but I'm worried that

    the lack of wide angle will become frustrating. Will I be constantly

    swapping with the kit lens to get wider shots?

     

    Canon 17-85 USM IS - The extra focal length I get over the kit lens

    isn't worth the money (obviously the lens is better and it has

    stabilisation, but in terms of use you don't gain much zoom power,

    which is my current complaint). It's format makes it unsuitable for

    full frame cameras, should I ever win the lottery.

     

    Sigma 18-125mm - I lovely zoom range, but when you use it side-by-

    side with the 28-135 it's slower, darker and noisier. Plus you don't

    get the Stabilisation. Other disadvantages include the fact that it's

    EF-S (reducing my upgrade path is the distant future) and the fact

    that its not Canon (will it work on future cameras? lower quality

    optics?)

     

    Ideally I'd like a Canon 18-135mm USM IS, but I'm guessing that I'll

    be waiting a while for that. Also, alll-in-one lenses aren't often

    the best choice either.

     

    Another possibility is to go with the 28-135mm with the intention of

    getting a wide angl complement, but from a budget point of view

    that'll be a very long way off. How limiting is the 28mm 'wide' angle?

     

    Can anyone offer my some good advice?

     

    Thanks,

  8. Hi,

     

    I've recently upgraded my EOS 300N to the 300D. I'm facing a few

    focusing issues and was wondering if any of you could shed some light

    for me.

     

    Firstly, does anyone here effectively use the automatic choice of

    focus point? My experience so far leads me to believe that:

     

    1) It hardly ever chooses the right point

    2) The focus point chosen is rarely the nearest point, as described in

    the manual

     

    It seems more useful to me to just select the center focus point, then

    focus, recompose and shoot.

     

    Are the other points of any real use? I envisage that setting up a

    composition on a tripod and selecting the appropriate focus point such

    that the camera need no longer be moved is the only time I would ever

    find this useful. Am I missing something?

     

    On a side note, I find that the camera jumps into AI-servo mode

    incredibly easily. How can this be avoided?
