    I am not a huge fan of "sub compacts" for tank work. That may be a great choice for an around the house camera, easy to take with you on vacation etc. That particular model is not well suited for any ONE particular thing, rather a jack of all trades type.

    That being said, finding a capable point and shoot for tank work is not easy. Admittedly I am out of the loop on current models, however the Canon G series performed wonderfully, as did a few of the higher end Nikon's.

    On the rebel av is the way to go in my opinion. Aperture above 8.0, I use high ISO but that can mean grainy pictures in raw format. At least that's my understanding...

    thats correct. You can lower shutter and lower Iso if you want to keep f stop

    Hi Mike. I am going to buy camera for aquarium photography. Is the Canon 6d with 100mm macro or 50mm macro better option to me. I like your pictures. Very nice! Thanks.

    Trying to figure this one out. I've been shooting in "M" mode on my Canon 5ti, but now I'm seeing lots of people use Av. Should I use that instead? Just got a new Tamron 90mm, and I've been playing with it for about 20 minutes...so far I'm getting my tail kicked in by this lens...not figuring it out very well. :cool::confused:

    If you using Manual, set the iso high(1000?) Then choose a shutter speed(1/100?) Set for 2.8. If the exposure is too bright increase shutter, OR Fstop OR iso.

    Av is Aperture priority. Set the aperture and the shutter speed will be chosen for you. I generally choose Aperture priority or manual.(fast)

    The benefit of manual is you can increase the DOF for effect OR the shutter speed for effect(fish and fast things)

    On Iso Id pic the on just below where it gets grainy. Go to manual, leave the lens cap on and increase iso in one stop increments and look at it on the computer.


    Fun stuff bro! Can't wait for the pics!

    No sweat. Its an easy one to practice while your sitting around before you get to the tank.

    it’s in focus but only a certain part is. looks like the pine cone or bark, or whatever that is.

    a little more explanation.....

    when you open an aperature (1.8, 2.8, etc) you are letting more light into the lens. this is what throws off your exposure and why you would need to also adjust your iso and/or shutter speed. i recommend everyone shoots in manual so they have full control over their settings. you can easily detect what your limitations are for your environment. and just the opposite, when you close the aperature (ex 11) you are letting less light into the lens.

    the quality of blur produced by having a shallow depth of field is what we refer to as “bokeh”. not all cameras/lenses produce the same quality of bokeh. usually not a concern if you’re shooting your fish tank, but’s important for portrait or wedding photography.
