My superb four-lens 12mm to 45mm kit

OK, yeah, I can certainly see where they would be perfect for the PEN series bodies. I've got the 12 and 17 and they both are wonderful on my OM-5.

You should have a look at Derek Forss' YouTube channel. He does a lot of photography inside dark churches and cathedrals using the Olympus 12-100 f/4. The IBIS in his E-M1 is sufficient to allow him to go down to very low shutter speeds and get superb photos. And he typically shoots at ISO 200 to boot. Now I do understand that Olympus' IBIS is superior to Panasonic but I wouldn't think it would be that much so.

The three photos in the post that I was replying to didn't imply subject motion so my comment for those situations does pertain. In his subsequent post he shared photos with (potentially) lots of movement so yes, faster shutter speeds are needed and thus a faster lens.

Part of my motivation to get 8mm F1.8 recently was for low light situations. The F4 zooms not very slow, but also not fast enough, even with Sync IS.

I like the small size of 8mm, but the difference can be a little distracting, so I probably will not bring it together with one of the zooms very often.

"Interchangeable lens camera" to me is more about being able to customize the camera than about constantly changing lenses while shooting.

Yes, I'm well aware of how IBIS works ISO1600, 4 second hand held exposure with my G9

A fast prime simply gives more options. IBIS won't solve everything

It’s a nice kit, but not in the minimalist category (if you would just take a Ricoh GR with you as an example, this would I consider minimalist). But two bodies & minimalist? Nah, doesn’t compute.

I have a Ricoh GR 11 and 111 and a GR Digital .... the first model...as well as a GR film. So, I am a minimalist 4x over :-).... Actually, while I think the Ricoh is a minimalist camera it is also limiting..... I grow a bit tired of the LCD and always viewing thru it like a phone. Coming from the Analog world, I prefer my OM1 and OM2's....with nice big, bright view finders. . I am hoping to find a nice digital such as the Pen-F...although I see in the original posting here that Hiker Jim stated that the Pen-F was his lightweight, whatever that might mean. Either way, it would be the really only digital 'heavy weight' in my analog world...

I love the 12-45 F4Pro + the P20mm f1.7 as a combo.

But heck, I love the P12-32 + the P20mm f1.7 as a combo, too.

To really go light, no contest, it would be just the P20mm f1.7, but I've been eyeing the 20mm f1.4 PRO and would love more input on it. All i hear about is discussion of its blurry-bg capabilities, which I don't care about. How is it as an everything-in-focus lens? Would love to have a full-weather-sealed fast prime in a focal length I like . . .

For me....I usually take two lens and then a Ricoh GR... But depending on the type of photography I am looking at doing, I will carry around a 24mm (35 =) and a 50-55mm (35=)... I usually go with some project / purpose in mind so can adjust the lens focal length depending ....
