Thrasher (Two Photographs and some notes on the resolution of long lenses)

I like this little Thrasher perhaps because it was my first sighting of this kind of bird. We saw it from far off and took a few pictures. As we got closer it flew off. Whenever you use a long lens over a great distance, issues arise from air quality, to temperature, to the limits of the lens and sensor resolution that will impact the quality of the photo. To some degree sharpening and noise reduction will help, more the latter than the former. Very long lenses are very inviting but they have their limits (e.g. weight). It is a fact that the closer you are to the subject, regardless of lens, the better quality photograph you will get.

  2. Very good captures of the Thrasher! Even with a long lens, you still need good light, unless you are going for the special effects. 🙂

  3. As you know I own an 800mm lens and I wholeheartedly agree with your thoughts. My favourite lens is 400mm – much more versatile. The 800 is great off a tripod in decent light but its not user-friendly to an old un. But it has got me shots I would not otherwise have got. Closer is always better though.

    • I have seen the 800mm in the field. Very impressive.I am comfortable with the 300 2.8, and will look at the new 200-500mm as it might be a good option.

      • Who is making that Victor? It sounds interesting.

        • Nikon, an F5.6 lens going for about $1700. I had a chance to meet someone who has s copy and he is happy with it I read a bit on the quality. Its supposed to be better than the 80-400 that Nikon just released. Too much hype about the 200-500 right now to make a good judgement.

  4. I recently looked at the new Nikon and am still debating getting a Sigma 150-600mm Sport lens instead, although it is a few hundred more, it has a bit more reach. Highly rated too.

    • Yes but a variable aperture through the zoom. Makes it complicated.

      • True, light fall off too. But the price of the Sigma. I tried it out and it seem like a good lens. The 200-500mm Nikon is tempting as well, but like you have not seen enough great reviews yet. I just need a bit more reach for eagles. Not sure it works with a tele-convertor. That may make a difference.

  5. Tony Sweet (who’s opinion I value) is saying the new 200-599 Nikon lens is terrific. I’m not thrilled with the 5.6 tho. I still love my 70-200 2.8 so will just have to be good at sneaking up on wildlife and birds!! Love shots in the one Victor.

  6. Happy for you to see and photograph the thrasher! You brought up some interesting thoughts to ponder, reach, weight, aperture. After owning the 80-400 for better than a year and recently adding the 200-500 a couple months ago I find the latter is used mostly because of the constant aperture. We can throw all sorts of money into gear to get “the shot” but more importantly is understanding the behavior of the wildlife we are photographing. Once we have that it’s easier to get close enough to the subject that they are comfortable with our presence.

    • Thanks. I am very interested in finding out more about the handling and image quality of the 200-400. The lens being new there is not a lot of information out there on it.

  7. What a lucky sighting…they are pretty shy birds!
