So, a thread about shutter shock without any images?

Haven't had the time while at work to test it and I don't have the camera with me atm. I'm thinking most of my issue is actually with my copy of the 35-100mm. It exhibits pretty heavy flare... like sort of a glowy mist on highlighted areas that really drop the sharpness (with the lens hood on, not shooting directly into the sun). This is likely due to the lens being pretty meh at 100mm wide open. I knew it wasn't going to be ultra sharp wide open at the long end of the zoom, but I thought it would be better than what I'm getting out of it. I also own the 12-40mm, and many have complained its soft at 40, but its no where near as soft at 40 as my 35-100mm is at 100mm.

But for posterity, I will post some shutter shock samples tomorrow. It exists, and its quite prevalent with the 35-100mm. Luckily I shoot mostly with the E-shutter, though I feel like I've been having focusing issues in that mode lately. Again, It is entirely possible it is a fault of the lens and not the camera.

Both lenses have a problem at the long end where user shake comes into play? Seems unlikely it's a lens problem . Time to get a tripod and test it. Some people just can't hand-hold as well as others.

I highly doubt this is the problem, as what I'm seeing is happening with dual IS and with shutter speeds well over 1/200th a second.

1/200 of a second is in no way a sure thing with a 100mm lens. Especially in the heat of a wedding.

The old, 1/focal length rule works for 35mm cameras, making prints and slides. If you are going to look at pixels on a computer and you want absolute sharpness you need one or more of these things with long lenses: A very steady hand, a tripod, a fast (1/500) shutter speed, Great IS, or Luck.

I still would love to see the examples.

GX8 // 35-100mm f2.8 @100mm // 1/640th sec // 0EV // ISO200 // DUAL IS mode

GX8 // 35-100mm f2.8 @100mm // 1/500th sec // 0EV // ISO200 // DUAL IS mode

I did no post processing on these images. Just opened the RAW, kept the default ACR sharpening ( 25 at 1.0 size) then saved it as a JPEG.

Zoom in on the face and you'll see its hazy and quite soft. I know its not going to be biting sharp, but this is MUCH softer than my Oly 12-40 at 40mm. Not really that acceptable to me for what you pay for this lens, and if I was actually on assignment, I would either not use this lens at 100mm f2.8, or if I need the light I'd shoot it at around 75mm.

The top shot does look soft, but there's no hint of directional blur that you'd expect from the shutter travel, except possibly at the top of the zipper on her hoodie, where there's a bit of glow. Could just be from the brightness of the white.

On the closeup shot, her eyes are soft, but her hair on the left side is tack sharp.

This leads me to suggest that the problem may not be shutter shock, but focus.

I was hoping for images from the original poster who started this.

but, since you posted:

I think there's things going on, but not shutter shock. Otherwise the pattern in this area would not be so clear.

If you ask me this looks like a dirty lens, dirty filter, flare from lack of a hood, or some other factor introducing softness. Maybe just a lens that's not up to par.

Although that is what it looks like: The lens is clean, and the lens hood is on the camera. I think it is a copy that is just not up to par. Oh well, at $700 I guess I can deal with it being a 35-100mm f2.8-f4 lens.
