Trenitalia Double Deck at Roma Trastevere; Zoom versus Prime

It was a bright morning last week when I exposed this view of a Trenitalia double-deck suburban train approaching its station stop at Rome Trastevere en route to Roma Termini (Rome’s main station).

I worked with my FujiFilm XT1 with 90mm f2.0 lens for this photo.

Exposed using a FujiFilm XT1 fitted with a Fujinon f2.0 90mm lens.

Regular readers may have noticed that I’ve been making regular use of this camera/lens combination.

I have four lens for my FujiFilm XT1; 12/27/90mm fixed focal length (prime) lenses, plus an 18-135mm zoom lens. Lately the 27 and 90mm primes have been the most useful.

Why not use the zoom lens more? Here’s three reasons:

1) The 18-135mm zoom not as fast as the primes. My 90mm f2 is 2.5/3 stops faster that the 18-135mm.

2) The 18-135mm zoom isn’t as sharp.

3) I find that the discipline of working with a fixed focal length lenses lends to stronger images. This is an abstract notion, but often seems to be true.

Over the years I’ve gone back and forth between a preference for zooms over primes. It’s the toss up of convenience over image quality. There’s no one ‘right’ solution. But when I look back at my images that I prize the most, many of them have been exposed using prime glass.
