Smile Calculating exposure using extention tubes

Recently purchased old stock but brand new Bronica 42mm extention tubes from (Jessops of all places) - silly price on their website £34 but on reading the manual, it states you need to increase exposure because they is less light entering the lens and you are probably closer to you subject.

I have a Bronica ETRSi (no metering) but do have WLF and a plain prism. I was wondering if I could still use my external meter as I would normally and still get correct exposure?

I assume I won't need to make any exposure compensation if I stick to either incident or spot using my sekonic. Am I correct in this assumption and if so, which external metering pattern would be better. If I went spot I could place a grey card in front of my subject - any tips!

The manual seems to reference exp. compensation when using an AE prism.

Can't afford a macro lens so, I thought I'll have some fun and experiment with using tubes instead.

Thanks for any tips and advice
