Top Top Quality.


I changed the sharpness and saturation in Camera RAW and then resized and framed it in PS.

Thought you mught like to see these, they are pics of "Network Rail's" HST Measurement Train more commonly known to us as "The Flying Banana" but first a quote from Network rail as to what it does...
"New measurement train
The award-winning New Measurement Train (NMT) provides valuable information to our engineers on asset condition. The NMT is able to travel at up to 125mph allowing it to slot in between timetabled trains and is key to the delivery of the company’s objective to replace manual inspection with mechanised measurement.

The train, as well as producing video recordings of the infrastructure and the wheel/rail interface, provides six foot gauging data and information on track geometry. On board there is also a fully equipped conference facility for up to 12 delegates."

1) At Shottesbrooke on it's way from Plymouth to Paddington as 1Z19

2) Returning as 1Z21 from Paddington to it's home at Derby Etches Park

Image

3) 1Z21 passes "Turbo" 165107 on an up stopper to Paddington

Hello, just wanted to show how the IS in this lens performs. All photos were taken at 200mm f/4 and with ISO 100 and are clickable for full size download at deviantART for pixel peeping.

EDIT: All shots were taken hand held.

Image
Shutter speed: 1/4th of a second. Here the focus was slightly behind the bird, though.

Image
Shutter speed: 1/3rd of a second.

Image
Shutter speed: 1/15th of a second.

Can somebody explain the switch on the side of this lens that is marked with the choices "1.2m - infinity" and "2m - infinity"? :?

Focus limit switch. If all your subjects are at a distance, switch it to 2m to infinity so that the camera won't bother trying to focus in the 1.2 to 2m range and it will boost your AF speed.

Thanks! :D

I couldn't find the instructions for this lens on the web, and that was my only question about it.

I just recently got this lens, and have a question I hope someone can help me out with.

When the IS is turned on, and I press the shutter button half-way, you can hear something turning inside. It's obviously stabilizer doing it's thing, but I was kind of surprised at the noise. When I tried one out at the store, I don't remember it making any noise. (Maybe the store was noisy and I just didn't notice.)

So, is that normal, this sound of a something rotating inside? Or should it be silent?

Mine sounds like a coffee grinding machine , but much quieter , and yeah it's normal :) Some lenses with IS are noiseless , and some are like the 70-200 f/4 IS , or worse :p

"The following shot of the Orion Nebula was made with a stack of three frames, each of 60 seconds duration at 200mm and f/4..."



how did you achieve this shot? Did you have your dslr attatched to a mount and a telescope?

Trains seem to be popular shots here, i love the nice old fashioned trains, all these sleek new speedy trains are boring, good to see more and more people taking shots of the old trains.
