Can you use just one lens on an entire trip? A “walkabout lens” can be an excellent way to lighten the load during a trip while still getting high-quality images. I used the relatively inexpensive Pentax 28-105mm lens exclusively for several trips. This is how it went.
The realization
I’ve gone on several consecutive night photography trips. During one of the trips, I began realizing that I hadn’t switched lenses. The Pentax 28-105mm lens had been “glued” to the Pentax K-1 the entire time.
Longer star trails quicker
Since I was photographing star trails, I began using a longer focal length. This way, the star trails would appear longer, and I wouldn’t have to wait as long for them to streak by in the image. I was pleased with the images I was getting. Nice and sharp.
Going wide
I met up with a friend for two nights of photography near Barstow. Typically, a lot of night photographers gravitate toward ultra wide-angle lenses. And with good reason. We often want to photograph much of the sky. I was finding that since the wide-angle part overlapped slightly with the 15-30mm, which I was used to, I could photograph quite a few things with a focal length that worked well.
Taming distortion
However, if I backed up just a little and used a longer focal length, much of the keystoning (where a building looks like it’s leaning backward) and barrel distortion that was typical of ultra wide-angle lenses went away. I had to do more walking but less processing. That was a great trade-off.
Flexibility
For one photo would be up close. I would use the wide-angle of 28mm to jam the camera up close and get some slight wanted distortion or beautiful detail. For the next photo, I could photograph a building from the street but use some of the telephoto to bring it closer, compressing the scene.
The flexibility of having something that was 28-105mm and sharp just about all the way through its focal length was nice to use.
Variable aperture? No problem!
For much of my full moon photography, I use an aperture of f/8. The middle apertures of most lenses, typically around f/8 to f/11, are the sharpest. The Pentax 28-105mm is no exception. Since I was photographing at f/8 during a full moon, it didn’t matter if the lens had a variable aperture from f/3.5 to f/5.6. My aperture would never change anyway.
Flexibility with day photos
I used the lens during the day as well. Returning from Borrego Springs, I pulled over to the side of the road to photograph a horse. The wide-angle helped me get close. But the extra “reach” that the lens had made it so I could photograph the horse from farther away if the horse was more shy.
Five consecutive trips with the same lens!
I’ve now gone on five consecutive night photography trips over a six-month period. I have not taken the lens off for any of the trips. I have taken it off at home to clean it or to use the Pentax 50mm f/4 macro lens to create some videos of colorfully lit bubbles.
However, on the five trips, I’ve had the 28-105mm lens on the entire time.
During this time, I’ve used it for a wide variety of scenarios.
I’ve photographed abandoned cars, buildings, sculptures, day hikes, product photographs, and portraits of friends. It’s performed admirably for all of the above. If you can find a good quality “walkabout” lens, you just may find yourself keeping it on the camera for long periods of time as well.
I have a Canon 24-105mm EF L. It is a very versatile lens. I use it for street photography. I recently used it for a choir service in a church. It has two advantages: it’s versatile and it’s lightweight. It is also not as sharp nor as fast as my other Canon L lenses. Also not their equal in build quality, despite being a Canon L lens. Occasional and amateur photographers might be satisfied using it as a.single lens on a family vacation. A more avid amateur and certainly a semi-pro or pro who is making the trip entirely or… Read more »
I didn’t intend on using one lens for multiple trips. I happened to notice that I had the 28-105mm “glued” to the camera after several trips. That said, there’s ways around much of what you say. First of all, as you have seen, a 28-105mm is fantastic for night photography. If you want wider, sure, absolutely, but you’d be surprised at how many night photos you can take above 30mm, whether doing Milky Way (often via tracking or Pentax’s Astrotracer) or night photography with light painting when the moon is out. I know people who are photographing the Milky Way… Read more »
