Re: How many extension tubes needed?

The number of extension tubes you need depends on the lens you want to use and the magnification you want to achieve. I use this site to get a pretty good idea:

With your 50mm f/1.4, with 37mm of extension you can reach magnifications of just under 0.75x. With 74mm, you can reach magnifications of just under 1.5x.

I miss the days when I used to be nostalgic.
