You can go with cheap metal tubes, but as mentioned you will lose aperture control and autofocus (I always manually focus when doing macro). I have a set of these too since they were $8 and I got them first. |
To help me try to understand what they do......You say use them wit your 50MM prime lens so can yu explain what they do to your lens that it can't do as a 50 mm lens?
