IBIS with 70-200f4 is quite poor on SL2 during lens testing at infinity handhold. I still investigate: is that due to focusing error, more pixels, or IBIS or Lens OIS integration with SL2 IBIS or there is some bug in my shutter speed region (I set it at 1/125 and let AutoISO does rest and lighting was poor). or Maybe I just need use silent shutter, there is no EFC in SL2. Too many variables, I think It will cost me some time to figure it out.
Not many will care anyway, I will quote myself one more time to make it complete. I figured out why 70-200 is not perform good on SL2. It is the mechanical shutter of SL2. S1 have no such an issue given it has EFCS but not with SL2. S1's mechanical shutter (with 70-200f4) also perform way better than SL2 even SL2 has very beautiful shutter sound. I am pretty sure if its Nikon or Canon or Sony, this problem will blow out all over the internet.
I did extensive test find out that for SL2 with 70-200 work consistently at any shots less than 1/125, I have to use e-shutter. This lens is good BTW. I haven't noticed the problem with M glasses but maybe they are not long enough to show the issue or I just didn't look for as hard.
I hate this find out stage for any new system to me, from lens to body but you all can see this is a very important step to have no surprise in field.
Thanks for the update. It's ridiculous the SL2 doesn't have an EFCS. Mirrorless bodies are particularly prone to shutter shock because they have to first close the second mechanical curtain before starting an exposure (since the first curtain is open to support full-time live view) and the vibration that operation resonates during the subsequent exposure after the first mechanical curtain is opened. Another downside to fully mechanical curtains on mirrorless is it doubles the amount of wear on the shutter.
