Nature and outdoor photographers will tell you that you can never have too long of a lens – the more millimeters, the better! I’m one of those photographers.
For me a single lens that has wide angle settings for inclusive scenes and can zoom out to capture distant subjects is preferable to carrying multiple lenses. The lens that attracted my attention was an 18mm to 300mm zoom. However I was only able to find one made for APS-C sensor cameras.
My main camera has a large full-frame sensor with a resolution of 9504 x 6336 pixels. Luckily it can accept APS-C lenses although the sensor resolution is reduced to 6240 x 4160 pixels.
Here’s a small gallery comparing the relative image sizes when using the APS-C lens and full-frame lens. While these samples are not subjects from the outdoors I hope that they illustrate the concept of mm reach.
Below are side by side sample photos taken at various lens setting. The photos on the left were all taken with the Tamron APS-C lens. The photos on the right were taken with the Sony full frame lens.
Keep in mind that although the subject size is smaller on the right, there are more pixels available if you crop the image in post processing.
For me, the bonus in using the Tamron lens is the addition of reach up to 300mm which gives me the ability to capture more distant subjects from a single lens.
I just returned from a recent trip with my full frame Sony camera and the Tamron lens. The two photos below were taken from a distance and the extra mm’s gave me a more detailed images of the two birds.
My back was grateful too since I was weighted down with only a single lens instead of two lenses that could offer me the same range.
As a bonus I can use the new Tamron lens with my older and smaller APS-C size Sony A6000 camera.

Zambriskie Point is of my favorite areas to visit in Death Valley. I am awed by its magnificent landscape created by millions of years of erosion. When climb the steep path from the visitor entrance, you’re immediately greeted by the heavily textured, sandy colored alluvial fans.
This day as I walked up the path I could barely see two people standing on one of the flat areas in the distance. They looked like ants on the rocks. The juxtaposition of the tiny figures against the huge backdrop of these badlands was an interesting view.

My equipment was a Sony NEX-7 camera with a medium 18-200mm zoom lens. This is the image that I captured of the couple. The EXIF data tells me that the lens was zoomed to 44mm. |

The above photo was the only one that I took of the couple. When I viewed the image in my “computer darkroom”, I wanted to see how the scene would look if I had used the zoom feature of the lens. I magically zoomed by cropping the original image. The result is that the couple and the rocky landscape show up in much more detail. Which one do you preferr? |

While I like both images, I prefer the zoomed in version. This is an example of composing your image after the fact.
Creative framing is one of the secrets to taking top notch photos.

Often, the photographer feels compelled to frame the entire subject. But you may find it equally interesting to be more selective about how much of the subject to include in the viewfinder. Suggestion: Move Closer I call this zooming with my feet. |

 Here we’ve included most of the wooden sculpture. You can see that the background is slightly distracting. |
 By moving closer to the sculpture, we have paid special attention to the face and also eliminated the background. |
 The large number of balloons make for a very colorful scene. However, the balloons don’t stand out very well because of the building in the background. |
 For this shot, we concentrated on a single balloon. By moving closer to the balloon, we are able to isolate its bright color against the blue sky. |
