Hmmm I will definitely keep an eye out for one of those! Having said that, I got my Oly 35mm VF-1 today, on the RX100 it is brilliant! I usually use this camera between 28 and 50mm anyway, so between these two finders I am pretty happy. They are tiny and weigh almost nothing, easy to keep in a pocket and just make everything enjoyable to shoot. VFs both line up very nicely, use centre point focus and recompose, what is in the centre of both VFs is what the RX100 grabs focus on, which is usually very fast and accurate - have done loads of tests and can shoot using these with a great degree of confidence (despite being a bit of a hack job). Really happy!
