I am retiring soon and will be embarking on some semi-exotic travel. Places I won't get to twice. Should I be courageous and only bring m 4/3 gear ? I should have the new EM1 mkii by then and will bring an em5 mkii as a backup body. Or should I take the "safe" route and bring my FF gear. My website is mysticeyestudios.com I am not a big portrait guy. I love Oly glass and have found it to meet my needs but, these will be once in a lifetime opportunities. What do you think ?
