Thanks for the info!

Would be interesting to see 32 mm Zeiss VS 30 mm Sigma comparison.

I'm using Lowepro Dashpoint 30 - it fits my Nex 6 with either 16-50 PZ or 19/30 mm Sigma (need to revert hood on 19 mm though). Has both detachable shoulder strap (never used) and belt loop.

IMO, these shots (especially first two) have rather hard light conditions to begin with. They both have bright sky and well lit white elements, dark ships, dark water and even darker shadows....

Good luck finding one that is slim enough for PZ. I tried standard Tiffen from Amazon (I use them on almost all of my lenses), but it seems to be too thick and I got strong vignetting on 16 mm. So...

It certainly does: I really love both 30 mm and 19 mm Sigmas - they are true gems in a cheap plastic casing :)

It's hard to tell without seeing actual shots, but if you use in-camera auto metering and your scene has some really bright areas - in this case underexposing of darker areas is totally expected.

There is no such thing as "equivalent F number", unless you're talking about keeping the same DoF on lenses with different focal length

I'm using Lowepro Dashpoint 30 case. It is compact, relatively inexpensive, has belt mounting option and just enough room for my Nex-6 with either Sigma 30 mm or Sigma 19 mm on it.

I think the best way to figure out if you need them is to put a 30 mm on your camera and leave your PZ at home before your next trip.

Short answer: yes, buy it. Optically 19 mm Sigma is way better than kit PZ (I have both) - it is super sharp and has very little distortion for its focal length. Actually, I truly believe that...

Check the Nikon 100 mm f2.8 AI-S Series E - they're very good lenses and could be found for ~$100

Google for "wildlife management"

Wow, I really didn't expect that much ignorant tree-hugging comments on dpreview!

FYI, Nikion makes this particular series ("Monarch African") of riflescopes for years, but you didn't care until...
