Thanks to you all. You gave me some good ideas. I went ahead and bought the Lowepro Dashpoint 20 for my DFA 100 and the Lowepro Santiago DV35 that can hold any combination of two DA limited primes. I did try a different sunglasses case that was similar in size to your Suncloud but the OpTech double cap made it too fat to fit; also, I preferred that the case open on the vertical side rather than the horizontal orientation. This seems to work for what I'm looking for. The Santiago DV35 doesn't have much soft padding on the inside, but the shell is pretty stiff and seems to offer good protection. Previously, I kept looking for "lens pouches" and lens oriented bags and just couldn't find a good fit until now. I appreciate your help. Some images attached.
