I've been having an internal debate about a new lens acquisition (and consolidation) as I've been getting more familiar with the types of photos I enjoy capturing the most and have been working out the lens kit that best fits my style. One approach I've been using is to look at my own library to sort out my lens usage. While another is to use places like Flickr and 500px to filter through photos shot with specific lenses. From these methods I started getting a better idea of which types of photos appealed most to me, in terms of visual qualities like focal length, depth-of-field, sharpness, etc. I stumbled on a site called whatthelens.com via this recent DPReview article: This simple web tool helps you find the lenses you like best Great work by the developer on this as it happened to reinforce my own findings on favorite lenses. For me, it primarily suggested the 75mm f1.8 from Olympus and the 35-100mm f2.8 from Panasonic. I happen to already have the 75mm, which coincides with the recommendation, and the Panny 35-100 has been on my radar for a while now (in contention with the new Oly 12-100 f4). As secondary choices, the 42.5 Nocticron & Oly 45 f1.8 were also suggested. So it looks like my style preferences lean into the telephoto range, though one round came up with the Oly 17 f1.8 as a choice. Give it a whirl and share your findings!
