    Hi all,
    I wanted to ask if someone played already with extension tubes in the past and if they can be used also for portrait shoots, taking even shallower depth of field and larger bokeh.

    How much they influence the optical quality of a lense?
    I would like to thank you in advance for your reply

    Extension tubes enlarge the image circle so resolution goes down a bit. Amount depends about magnification. They don't affect depth of field (it is same for given focal length, aperture and focusing distance) but allow focusing nearer. Not useful for portraiture.
