Well Stix, yourself, others have convinced me to go bigger - against my initial wants...so I’ve gone 30mm tube and 50mm bell...I mean objective lens. Mark 4 4-14 Leo. $1200 brand new. It’s heavier by 200 grams than the 40mm so I’ll have to have a wee before setting off to offset additional weight.
Can’t wait to mount the big bell end and show the missus
