I have been thinking about ways to lighten the load. Many people recommended M4/3 as doing just that so, as an exercise I priced an Olympus kit. 1.4x converter 7-14 f2.8 14-40 f2.8 40-150 f2.8 300 f4 Around £4,500 used Two OM-D E-M1X or E-M1 Mk III bodies, with grips as appropriate, £3,000 Total, £7,500! Back to the drawing board. I haven’t even bothered to see what the weight saving might be, any one have a better (cheaper) suggestion? Slower lenses and/or losing the grips aren’t options.
