Well, having been shooting mirrorless for the last twenty months, I am now completely changing the way I approach my photography. I have accumulated a few high quality but fairly sizable lenses (Sigma 12-24 and Minolta Beercan in A-mount, and SELP18105/4). However, in the last several months I definitely started to prefer portability over the ultimate IQ (as long as the difference is not major, of course). So, I am slowly making a full circle and getting to the point where most E mount shooters probably start - having a bunch of relatively cheap, portable glass in my bag. First, I sold the 12-24 and replaced with Sony 16/2.8 + UWA. The resulting combo is about 1/3rd the bulk and feels like 1/4th the weight. Yesterday, I bought a 55210 from a forum member. Still waiting for it to arrive, I fully expect it to live up to it's not super stellar reputation for slow aperture and slow AF, but decent IQ. I won't sell the Beercan any time soon. It was cheap after all. But, if I go on vacation or just out and about with family, I'd rather not carry that artillery shell with me. It will be there for dedicated, pre-planned use only, and 55210 for "just in case" situations. Finally, I've been using (and appreciating) the 1855 kit a whole lot more lately. It's sharp, and even when mounted on the camera, fits in my jacket pocket (if barely). It's not as universally useful as 18105 but it's much more of a "grab and go" lens. And it's so cheap and easy to replace I can take it anywhere. A small, about 12 x 11 x 4" messenger bag that I have will hold the camera, 16/2.8, UWA adapter, 18-55, 55-210, 30/2.8 and / or 50/1.8 OSS, spare batteries, and a bunch of small items - with room to spare, covering 12 to 210mm range. And since most lenses were bought used, I am not as worried to get it wet or lost / stolen. I will still keep 18-105/4, as it can replace both 1855 and 55210, and has a bit nicer IQ, but I think I'll try to do a whole vacation with just small cheap lenses & see how that turns out. I'd be tempted to play with 1650 if I can find it for really cheap (don't want to spend $150 and find out that it's really that much worse than 1855).
