    Canon SX60HS in Action

    If you are underexposing a backlit shot as you are indicating then it is no wonder you are getting a lot of noise - to correct the exposure you must need to 'push' a lot in processing and that is bad news as far as noise goes, especially if you are not using the optical focal length and shooting...

    Canon SX60HS in Action

    As I already said it is a fair heavy crop and was taken taken years ago - remember the SX40 only went to 840mm optical and I shot it on optical focal length only (also used RAW (via chdk). What do you mean by scaled !!! - it is cropped and obviously resized for the web. After I got rid of the...

    Canon SX60HS in Action

    While a lower ISO is of course preferable for a Camera with such a tiny sensor you should be able to go higher providing you get the exposure correct (ETTR) and do not crop too heavily. Attached is a pic from the now ancient SX40 which was taken at ISO 800 (and cropped a fair bit) - surely the...

    Canon SX60HS in Action

    There is no 'one setting fits all' when it comes to Ev comp, each scenario must be calculated on its own merits. Examples, a dark bird where there is strong back-light may take up to +3 to expose the bird correctly (and ETTR) whereas a light bird that is in strong sunlight may need a minus Ev...

    Canon SX60HS in Action

    Magnification is not really the right term here. A 400mm lens is always 400mm but if you put it on a 1.6 Crop Camera then the Camera will crop it to give a field of view (full frame equivalent) = to 640mm (400 x1.6). On the SX60 the max lens focal length is 247mm so it is always going to be...

    Canon SX60HS in Action

    The SX60 has a max focal length of 247mm, but because you have a tiny sensor the image gives a field of view = to 1365mm on a full frame Camera (its a 5.52 cropper) Where it says 158.8 mm that is = to around 876mm full frame equivalence field of view (e.g 158.8 * 5.52)

    Canon SX60HS in Action

    They are nice 'crazyfingers' but where you lose most with the small sensor Cams is when you have to crop heavily before you even resize for the web. Attached is an example of the original full frame and a near 100% crop taken with a 400/5.6 lens on my old 40D cam. On the 1.6 crop camera this...

    Canon SX60HS in Action

    I agree 100% with this Andy - these Cameras are great if you can get near enough but they do not yield anywhere near as much detail as a decent DSLR set-up if you take a shot from afar - with a DSLR set-up you can often crop the image extremely heavily and get some nice detail but not so with...

    No, I went back to the DSLR set-up although I do not snap many birds these days due to the weight.

    Canon SX60HS in Action

    about six months ago I read that Canon would be taking a new direction with the SX60 - I was hoping for a larger sensor even if it meant double the size/weight. The SX60 still has a tiny sensor which for me rules it out as AF and IQ will always be compromised. BTW I owned both the SX40 and then...
