I took a look at two camera bags I had ready to be used this weekend for photography. I use only one of these two small and light camera bags.
I have in one bag:
Leica M3 + Canon 50/1.2 and Hexar RF with Summicron 50/2
The other bag has in it:
Leica M6 + Summilux 35mm 1.4 and Bessa R + Heliar 50/3.5 and Standard Leica + 21mm Rokkor.
Here is a snapshot of the five sets.

Lenses are more important to me than cameras since the images are affected by the optics used.
1. The Canon 50/1.2 LTM is a very special lens that still can be bought at very reasonable prices. Its high speed makes it an excellent one-lens-travel-kit. When closed down,the lens is very sharp.
2. The Heliar 50/3.5 LTM is one of the sharpest lenses ever tested, and it has a lovely look to resulting images by it. I got my lens with a 101 year anniversary kit that also included an olive Bessa T.
3. The first version rigid Summicron 50/2 is a very high resolution lens that I find as a classic Leica lens without being surpassed by any 50mm lens in overall quality.
4. The second version Summilux 35mm 1.4 actually is a lens belonging to our Jim here. I am determined to buy it though. Even my wife ,who is not a photographer, likes the images a lot. She insists that I don't "waste money" on other lenses.
5. The W-Rokkor 21mm 4.0 is an old SLR lens in Minolta mount. I love the way this very sharp lens gives me nice looking images. The lens design is non-retro focus, and I must use distance guessing.I have a Minolta lens to Leica camera adapter that I bought locally about 15 years ago. Finally, I found use for it. A Russar 20mm finder is used with the lens.
This thread is not to gloat [but I do smile with pride] or boast, but it is to share with you what I like to use in photography. Each of these sets are very functional,and I find them all great for use. The standard Leica may be the oddball camera here, but it is butter smooth and ultra cool. I enjoy taking photos with this camera.
