  • Commented on 'Using Extension tubes'

    Quote:lCorrect, that's how extension tubes affect zooms.

    Thank you for clearing that up, I thought i was going mad!.

    Thank you every one for the replys, it has been very helpful. Can I then confirm that while using an extension tube, the aperture will be fixed, and that will depend upon the max aperture of the lens being used. Is that right?

  • Commented on 'Using Extension tubes'

    Apologies if this has been answered before, but I cannot seem to find the answer I'm looking for. While saving for a dedicated Macro lens I have started to play around with some cheap extension tubes. I have a Canon 400D and was using it on a a Canon 70-200mm lens. Because they are not the Canon specific model I lose autofocus thus have to use manual focus. I also assume that I lose the control over aperture as that just shows up as 00.

    What I found strange though was that the zoom function seemed not to work any more, it simply seemed to control focus, then the focus ring seemed to be a fine focus control. is that right?

    Also am I right in saying that to change the aperture I have to take the extension tubes off the camera, put on a lens, then amend the aperture, then put the extension tubes back on again. So in other words I cannot amend the aperture while using extension tubes, I have to put a lens on the camera?

    Many thanks in advance.

  • Commented on 'Canon Powershot A470 or Casio EXILIM EX-Z1080'


    Does anyone have any advice to offer please.
    I am buying my brother a digital camera as he is preparing for the arrival of his first child. He does not want anything too fancy and just wants a point & shoot camera (he was originally going to buy the cheapest camera possible from Tesco!). I have finalised it down to 2 cameras; the Canon Powershot A470 and the Casio EXILIM EX-Z1080.

    I can get the Canon Powershot A470 for 86.00 with a case a 1GB card. I can get the Casio EXILIM EX-Z1080 for 80 as it is in the sale, but would then need to get a case and card.

    On the face of it, the Casio is a much more expensive camera with 10MP, compared to the Canon's 7MP, but the downside of the Casio is less zoom and poor Macro facility. The Canon's picture quality is meant to be very good.

    What do other people think, or does anyone have any experience with either of these two cameras.

    Many thanks in advance

    Many thanks for everyone's comments so far, much appreciated. Valid point about not mentioning what I intend to use my camera for.

    Please help...........

    I am new to the whole world of digital photography and need some advice please. I have got a Canon 400D with kit lens (18-55mm). I have also purchased a 50mm 1.8mm lens.

    I was looking to replace my kit lens and also expand my range with a telephoto lens. With all the different lenses out there and with everyone having a opinion, it was getting very confusing in terms of which ones to buy. Eventually I managed to narrow it down to sticking with Canon lenses, and I thought I would go for the 17-85mm USM IS lens to replace my kit lens and then get the 70-300 mm USM IS lens. Roughly, this would cost 600. Now for some reason I have looked again and thought of another solution; the 18-55 mm IS lens and the 55 - 250 mm IS lens. Apart from losing 50 mm at the top end, the only thing I would be losing is USM on both lenses, but I would be saving half the money as I can get both for about 300.

    So firstly, is there anything else different apart from USM? and then is USM worth paying for?

    My understanding is that USM gives you faster autofocus and is quieter, is that worth paying more?

    Many Thanks in advance

  • Commented on 'RAW & JPEG Quality!'

    I have just been on a course with Experience Seminars (for Canon Camera Users) and apart from teaching me almost everything I need to know about my camera, it also opened my eyes to a lot of things.

    Before going into the course, I was adament that RAW is the way to go (better image quality), and it still maybe for some people. However on the course I was taught that the Canon JPEG compression is so good that it rivals RAW in quality, so much so that Getty images will only except images in a RAW format AND JPEG FINE from Canon EOS cameras. Now if it is good enough for them, then I figured that it would be good enough for me, plus I can fit a whole lot more images on to a memory card!

    The only thing that worries me, and I am yet to test this out, is that when shooting RAW, it was very easy to amend the colour balance when converting the image. I am not sure whether I can do this as easily when in JPEG. However, and this is the bit I need to test, with the camera comes some free software (DPP) which you can use to amend the picture styles after the shot has been taken, so I thought that if I can do this, I might be able to amend the JPEGs with it as well. With the software being free, I dismissed it and plumped straight for the Photoshop Elements, but after this course, I am going to try out this software!

    Also with JPEG's in mind, when shooting in JPEG on the Canon, you have certain picture styles. I have always left it in Standard mode, thinking that the picture styles were a bit of a gimic and thus leaving it in Standard mode would not affect my images. It transpires that the Canon camera (not sure if it is the same in other camera's) actually processes the image in-camera, thus if you are going to do some post-processing, then you would be processing the image twice, thus degrading the image. If you shot in Neutral or Faithful style, then there is no in-camera processing, thus when getting to Photoshop, this would be the first time the image is processed!

    So after my ramble, I come to the conclusion that I am going to shoot in JPEG fine with a neutral or faithful picture style, thus giving me good quality images that do not take up as much space as RAW. Also I do not need to convert my RAW images to be able to use them. The only doubt left is the ability to amend the colour balance in the PC software, but I shall find out!

    If you got his far, thank you for listening, what do you think?!

    Many thanks for all your input, I certainly have a few options to look at now.

    Thank you.

  • Commented on 'Replacement for the Kit lens'

    Hi, I'm new here so apologies if this has been asked before. I am looking at getting a replacement lens for the kit lens (18-55mm) that came with my Canon 400D. I am on quite a tight budget so cannot afford the better lenses such as the Canon L Series lenses, also I am not sure I would 'appreciate' those lenses being a complete beginner in the DSLR world.

    I was looking at the 70-300mm range but have also seen the 55-200mm ranges. Which manufacturer do I go with, do I go Canon, Sigma, Tamron........ Then there are the different options within the different manufacturers, for example with Sigma do I go with APO lenses or not.

    Another option would be to go second hand, I assume I would get a better lens for my money.

    Not sure if it is because I am new to the photography world or whether I am on a tight budget or both, or even something else, but I am getting lost in terms of which lens to go for.

    If it helps, the photography I am interested in are (in no particular order of preference):
    My kids

    Please help!!!
    Many thanks in advance
