    Meant to post this ages ago. This shot of my nephew is a good example how tricky depth of field can be at times when using wide apertures


    This was with my 85mm

    Has your lens got a "lens scale" on it Sean? may be good practise to start checking it before shooting if it has.

    Alternatively use the DOF preview button, unfortunately when we look through the lens of an SLR we are looking through it at its widest aperture, this is so the viewfinder can be nice and bright. That being the case if you are setting the widest aperture already, the preview button will be of little use, set it to F8 or higher and then try it, the viewfinder should darken as the lens stops down from wide open.

    Personally I'd go with a 50mm Sean (on a dslr due to the multiplyer) as the longer the focal lens the shallower depth of focus will be for subjects close to the camera when using a large aperture.

    The 50mm 1.8 MkII is imo quite perfect for portraits, well it is on my new 300d, yes I have joined the DSLR club :clap:

    Sorry to be picky, Zone, but it is depth of field not focus as you said. I wouldn't ordinarily bother, but depth of focus is also a photographic term which is not the same as depth of field.

    I've got the 50 1.4 and the 85 1.8 Si. It was at 2.8 Si, because i was using available light F8 was not an option. that's just an expample of how you have to get it bang on when you're dealing with large apertures.

    I do use the depth of field preview, just that's about the 100th shot of him that day and your going to have the odd slip at those apertures


    Could not part with my 85 Si

    It's a beautiful lens

    50 :(

    Bought a Ricoh SLR when I was about 20 and a bunch of low end accessories over the following years. Learnt a lot about photography but found it all a bit too expensive. Sort of gave up on it in my 30's. Discovered digital in my 40's starting with an epson VGA (yes all of 640 x 480) and have not looked back since.

    Hmm maybe I should not post this until I'm sober

    too late.

    Don't hold your breath mate :D Though I am keeping the A75 just in case ;)

    Defo a matter of time Sean, been a Canon 35mm user for many a year and fortunately most of my lenses are compatible as well :smashin:

    38 last month :thumbsdow

    Was given a 2nd or 3rd maybe even 4th hand Pentax Me for my 13th back in 1980 and have always had SLR's since but the costs of film/slides/processing just became too much back in the late 80's early 90's that I just left it alone until recently, thank god for digital :smashin:

    Anyway off to Blackpool for a dirty weekend tomorrow, hoping to find something "Strange" to enter for this months comp :D
