And people still praise OM systems for creating a ‘crop’ supertelephoto! So such a lens might have value, if purely for marketing.
Nobody praises OM's 150-600 for creating a crop super telephoto as everyone understands that it is the build and optical formula of Sigma's FF lens. OM gets hammered and criticized for it. Unjustly so, in my opinion, as supertelephotos's size is mostly based on the entrance pupil size, so when it comes to supertelephoto lenses, only the last optical elements can have a smaller diameter, thus reducing size and weight only minimally. If one compares the Olympus 150-400 lens with the 150-600, you will notice the only size reduction is in the last few inches of the lens. The advantage of an MFT crop sensor is obviously the fact that it gives you approximately a 2x reach advantage compared to a similar focal length lens and a similar MP sensor. For many, this is the BIG advantage of a crop sensor camera.
And when it comes to non-supertelephotos, then the lenses can be smaller in diameter, making the whole kit smaller and more manageable. From left to right: Canon 14-35 f4, OM 8-25 f4, Canon 24-105 f4, OM 12-100 f4, and the incredibly compact OM 70-300.
I understand the sophisticated camera users on forums and YouTube love to trash the Micro Four Thirds System and crop cameras in general, as they obviously want to preach the superiority of FF, and that only an ignorant fool would choose otherwise. And yet, despte their great intelligence, they are too stupid to understand that the constant negative publicity on social media - where most people today get their information - only hurts, and possibly will put, OM Systems out of business. It will make many happy, but if your system went out of business because of all the negative publicity, with thousands of dollars invested in it, wouldn't you rather people just shut up?
