If the focal length fits your style and traveling lightweight is appealing to you it would be easy to make a strong argument for the XF 27mm f/2.8 R WR.

The smaller the focal length, the greater the focusing area will be with an equivalent aperture, which is an advantage in street photography, where we try to have the most excellent focal length with as much light as possible). In my opinion, the main selling point for the 27mm lens is that it is both an ultra-compact pancake-style lens The 27mm focal length works out to around 41mm on a full frame camera, and hits the ‘human eye’ sweet spot of a 55.5° angle of view. I’m often torn between the width of my 23mm f/2 and the tighter composition of my 35mm f2, so the 27mm provides a nice middle ground. As I have told you, I have taken some first visible wave photographs and I am pleasantly satisfied despite the vignetting at wide apertures, although the autofocus is good and silent, and I am also doing IR tests at 720 and 590 nanometers and the results are Despite being almost winter, they promise great performance, especially at f8 and f5.6 apertures. My other surprise with this lens is that it behaves differently if you’re shooting at 720nm. or, 590nm. I had not found this situation in any other lens and, I assure you, I have tried many lenses from different manufacturers. That is why it makes it unique in IR.You don’t have to like the ’40mm’ view, of course, but I rather do – although I don’t have this lens yet. Compromise is much sneered at but it’s essential to most aspects of life. Without it, you get products that are perfect in one aspect but too big, too expensive or too hard to use – and that applies to many kinds of equipment, not just photographic.

Additionally, a tiny metal dome-shaped lens hood (LH-XF27) is also included in the box which screws into the 39mm filter threads on the front of the lens.Alas, the 40mm pancake re-invented for digital, again. Fuji has done a nice job in having a 3rd party build a compact lens and f2.8 is nice. Besides being purpose-built for digital,the good thing about this lens is the same as every other pancake lens ever invented. Its a small lens that is good enough in most other aspects. Its a compromise, that is all.
