This is for a Sekonic L-398, Studio Deluxe exposure meter.
I don't know how old it is, I bought it 2nd hand ten years ago. It works fine and I've come to trust it. The meter comes with its case, the 'high' filter for bright light and two attachments to replace the sphere with - I've never used these. I can't find the lanyard, but should it turn up, that's included also.
I'd like to get £35 for this plus postage which I don't think will be very high. I'll post worldwide and paypal is good!
