No I do not, main reason is the SHG lenses correct almost everything optically where the Pro lenses relay more on software correction. As great as software correction is, it is still not superior to optical correction. But, they had to compromise because of this (there is thread now about this) stupid perception that µ4/3 is suppose to be super small and light and tiny and I should be able to hide a 300mm ƒ4.0 lens and camera in my speedo. I rate the Pro lenses (300mm Pro not in this list yet because we really don't know the quality of it yet) equal to the HG lenses. Honestly I see no difference between my 50-200 and the 40-150 Pro and is why I got the 50-200, same IQ and longer reach. I do want the 40-150 for sports and for when I do need the faster AF, but most of my photography (just starting to get back into sports photography) does not require that faster focus speed.Yes, but those SHG lenses are as big or bigger than their f2.8 FF equivalents.
Honest opinion....do you think the SHG lenses are superior to the m43 Pros? I have the 12-40 pro and it's a fine lens but doesn't seem special. I occasionally wish I'd had my 17,1.8 or 25,1.4 even the 50,1.2 with me instead.
Speaking of the 300, Oly claims it is the sharpest lenses they have every made. I look forward to comparing it against my little tuna which honestly is the sharpest lens I have ever used.
