    Yup, there will surely be a tripod in the setup. (I have a tripod, but I'll look for another one better suited for this kind of work)

    I was thinking of some kind of closeup filter or extension tube BECAUSE my focal length is so long. I'll have some working distance to play with (a good idea ??)

    I tried reverse lens method, but lose all the Auto focus, exposure had to be manual in many cases. and the DOF is extremely narrow, which makes it an art to get it right. Also need to go to menu to change setting to allow shutter release, otherwise, the shutter is locked.

    I'm about to get Raynox 250, but not sure about the extension tube. if IQ is better with tube, perhaps I should go get the tube, but with AF control?

    Which is more convenient? I guess, once it is inconvenient like the reverse lens method, then we might use it less.

    ANyone got experience, can share if all the exposure, AF and the convenience of attaching them for both Raynox and Extension tube? I'm using the A55 currently.

    Cheers!

    Advantages of Raynox

    1. Don’t have to remove the lens
    2. Quick to snap ON and OFF
    3. Auto focus and exposure
    4. Very little light loss
    5. Can be use with filter size from 52mm to 67mm (Universal Adapter)
    6. Can vary magnification on a zoom lens
    7. Can stack a DCR-150 over DCR-250 to get even greater magnification (slight loss of quality)

    Note: It’s important to get the correct Raynox to suit your focal length

    The Raynox DCR-250 is best fitted onto a 100mm-135mm lens.

    Thanks much!! Diavonex!

    you had just answered my doubts. I tried using reverse lens with A55. it is definitely much easier than with my A350.

    But I think it can only meant for still shots on non-moving objects. as getting a good focus with such thin DOF is pretty challenging.

    If with Raynox, both the AF and exposure is still functioning as fast, then it will be very helpful in taking some insects which moves.

    I took Iphone's retina display with reverse sensor and it can capture what our naked eye can't see, that is the 3 small LED light bars, the magnification is very high and there far also very narrow DOF.

    When using Raynox the DOF will also be thin if you use a large aperture opening e.g. F4.5 or F5.6. You'll have to use smaller aperture opening like F11 or F16 to get good DOF.

    You may have to increase your ISO to shoot hand held or use a tripod. Alternatively you can use a flash to freeze the subject.

    If you want to use large aperture opening e.g. F4.5 and still have good DOF, a compact or bridge camera is better because of the small sensor.

    This is a compact camera using Raynox DCR-250



    This is a picture captured by the above compact

    When using auto focus with Raynox, you should use the selective AF point to shoot. If you use center-weighted, the insect's body may be sharp but the eyes may be OOF.

    On my Bridge Camera, I use the movable focusing point over the head of the insect before I hit the shutter.

    I'm using a Raynox 250 and 55-250mm Canon Lens, and my image shows no visible shake...

    Oh, and sorry for hijacking, but another question... One of the guys said you can use AF when focusing with Raynox, but how leh?
    I gave up, in the end, I turn to Manual, just move the camera very VERY gently back and forth until get what I want in focus, then snap XD

    I always use Auto Focus when using my Compact or Bridge Camera with the Raynox 250.

    Make sure you use Spot or Movable AF point. Position it over the head of the insect before you press the shutter.

    You can use Auto Focus with Raynox or Closeup Lens.

    Yeah. When I used my HS10, it auto focused as per normal, so I got quite surprised when it couldn't auto focus on my current set up...
    Is it my error or what?

    It's possible that you're outside the focusing range of the camera+Raynox. This range is very narrow.

    check your aperture setting. Sometime also if the subject is too dim focussing may be a b1tch.
