    You haven't said what your need for the excessive zoom range is - was my guess correct? The other possibility that should be considered is that the P510 might be faulty in some way. I did intend to post this but it slipped my mind in the rush.

    Truth is that with such small sensors, you've very little control over depth of field in any case.

    Very true, except that at the tele-end of a 42x zoom your depth of field is gonna be a bit minimal with any size sensor! ;):)

    OP prob will not go down the cheapo tele + adapr + mF/T camera but just out of interest, from your knowledge of optics from many years, what pre-set teles around the 300mm & 400mm mark would you recommend for reasonable performance at wide-ish open?
     
  5. Benchista

    Benchista Which Tyler

    Yes, although what does 42x actually mean? ;)

    From memory and personal experience (the one I have is a real dog), the 400s were generally poor - the 500s seem better, regardless of brand (in all honesty, I'm not sure how many actual manufacturers of such lenses there ever were). I've a 300mm Soligor that's not bad, and a 350mm whose name I can't recall that's OK, but I've got a Canon FD 300mm f5.6 FD that will fit any CSC with an adaptor that's better than either.

    I think, in this case, it's the 24mm wide end multiplied by 42 which gives the long end of 1000mm (approximations) in 35mm view equivalents.

    Sorry, I've just a bit of a bee in my bonnet about zoom ratios being quoted without quoting what the starting point is.

    42

    [This bit to make the post long enough to be acceptable; It's a right pain the diodes]

    That explains a lot. :)

    Me too. Just another number used by the marketeers - and bigger means better - of course :)

    Benchista Which Tyler

    Precisely.

    Okay, learning curve VERY steep here. I could only find one wheel - the knurled one on the back top right. What other wheel? I thought. I had no idea that the ring around the 'OK' button rotates. What a good thing I joined this forum :) Hopefully, I now have depth of field control. I'm now wondering what the knurled wheel is for.

    Have you discovered a way to get the focus to work reliably? I often find it focuses perfectly but then immediately loses it and shows a red 'can't focus' rectangle. If I can get this one solved, I'll be much happier with the camera.

    Thank you so much! Maybe I should change my logon name to "doesn'treadthemanual". :)

    Check the speccie. Or are you all out of Google or on a 'phone' at the mo?

    Probably 24/25/26, maybe 28.

    Doesn't matter. ;) If it was any higher, d.o.f. would be even less.

    Actually, a 42x zoom on a 38mm {135 equiv} w/a compact or bridge cam doesn't bear thinking about! :eek:

    Ohhh yesss! Another Churchill moment. Applies also to the 'spotty herbert' in the dealer who foists it on the unsuspecting customer irrespective of whether it meets their needs, they can hold the camera still at tele-extremes, they will ever use it at extreme tele, etc..

    Having said which, I have seen great evidence of the way average punters like to shoot at things from afar :rolleyes:, even when they can move much closer to the subject and obtain a better picture.

    Okay. I'm so pleased I joined this forum. I've learnt a load of stuff and received a lot of very rational (and tactful) guidance. Still wondering what 'OP' is and hoping it's not 'Old P...'. I've also learnt stuff about my own camera and am feeling better about my buying choice. Very grateful to all.

    I guess that my photography has moved on in the few months I've owned the Nikon p510 and that's why I'm looking for SLR features.

    So, the question posed in the original post develops... If I still want to move to DSLR capabilities I'll have to compromise zoom against technical capabilities. Obviously, technical capabilities win. A bit of research is showing 'compact system' cameras. Are these DSLRs? Do they have large sensors? Do they have the technical features I want? Manufacturers' web sites aren't always clear, especially when, like me, you're not sure what all the terms mean.

    In my experience that can happen with almost any AF camera (although less with the better/more expensive ones) and it just means that the AF system hasn't found the right contrast or shape/line differentiation to lock onto.

    You still haven't told us what you need this extreme tele for. It really does help us to help you.

    For example, although I haven't done a lot of bird photography and certainly not serious bird photography, I can foresee an AF situation where you set the AF selection point on the critters eye but the system finds it too small to pick up, or the surrounding feathers & eye are of such an even & similar tone there is no differentiation for a contrast detection system to pick up on.

    1. The zoom range is great as I live by the Solent. Lots of good subjects from animals to boats. However, such a massive zoom is a new toy. My previous (and still used) camera has a 16x.
    2. Yes, I know what everybody means when they say, "42x what?".
    3. I don't think the camera is faulty. It's much more likely to be the owner at fault.
    4. Guess what defunct camera retailer I bought the camera from.
