    Default 50mm lens + Extension tubes for macro photography

    hi all, just want to clarify a few issues with regards to above mentioned topic.

    I intend to do some macro shots (on a budget). have read many websites stating that the best way to do macro shots cheap, is to use an extension tube (eg. 24mm etc) with a prime 50mm lens.

    I have a EOS 550D (cropped sensor) and was wondering if there would be significant vignetting or drop in optical quality if I were to use this setup?

    Look forward to all your advice + comments.

    CANON EOS 550D, EF-S 18-55mm F3.5-5.6, EF-S 17-55mm F2.8, EF 75-300mm USM F4-5.6, EF 50mm F1.8

    There will be a slight drop in quality same as if you use an 1.4x or 2x extender.
    better to use a raynox 250 instead.

    Extension tube doesn't place additional glass elements between subject and camera. As such loss in image quality is minimal.

    Question Re: 50mm lens + Extension tubes for macro photography

    Hi all,

    I currently have 2 lenses: 1) canon 18-135mm kit lens 2) canon 50mm f1.8

    If I fitted my 50mm with the raynox 250, I still would'nt be able to get more than 1:1 mag right?

    A website calculated the mag to be only x 0.55.

    Is there are benefit in fitting the raynox to my 50mm (assuming the supposely better lens quality) since I'm quite sure that my 1) lens will be able to get more than 1:1 with the raynox...

    Appreciate all advice..
