I'm deciding between these two L-plates: http://www.ebay.com.au/itm/L-grip-Q...rca-Swiss-Olympus-OM-D-E-M1-EM1-/201160554531 http://www.ebay.com.au/itm/LB-EM1-Q...acket-Grip-For-Olympus-E-M1-EM1-/271870882738 The latter type is cheaper and has taller vertical bit that goes around the left strap lug. But the cable gap worries me. The clamp on my nodal rail is 40mm wide, and I guesstimated the gap to be 30ish mm. I needed this for panos, so if it's clamped aligned to the lens middle point there will be only 7mm on the bottom and 2mm on the top making contact. Is that safe enough or just play it safe? Thoughts?
