My next lens will be a wide angle Tokina
This little beauty is the next lens I'm going to purchase:
Its a very wide lens without much zoom range but what is so great about it is its large aperture(f2.8), which means it is very good in low light. I've read and heard other photographers rave about it and apparently it is the wide abgle lens to get for the money. It costs £500 roughly so i wont be buying it tomorrow but definately as soon as i can!

Chromatic Abberation
On examining some of my recent pictures i notcied a strange colour effect. Edges of objects had a strange purple fringing to them. This was most noticeable on shots taken with the telephoto lens on full zoom:
I was worried there was something wrong with my camera but it turned out this is a common problem called chromatic abberation. It often happens in images with strong contrast and is caused by different colours being refracted by a lens by different amounts. So, for example, the red wavelength is refracted more than other colors and lands on a different part of the sensor. It is common in poor lenses and especially zoom lenses at high magnification. My telephoto wasn't cheap to me but with a good quality L lens(canon's 'luxury' line of lenses) costing around £1000 it is all relative. Anyway the problem isnt that bad and is kept to a minimum by avoiding high contrast subjects and trying not to zoom in too much. Photoshop also has a filter that attemps to remove the problem --with varying results.
I'm going to try to get down to London Zoo this weekend.

London Calling...
Was in town today working, finished early and funnily enough i had my camera with me!
Mid afternoon on a sunny day meant that i could take the shutter speed right up, some of these pics were taken at 1/4000th sec. I ended up walking from Goodge street all the way to Waterloo, taking more than 100 snaps along the way:

Moon.
Ok, i thought i had finished for the day but then i noticed how clear the moon looked so i couldnt resist whipping out the telephoto and taking a few snaps.
Summer is here...

Nothing to see here...
Some poor shots today, felt uninspired though it did remind me what great bokeh the 50mil prime lense produces.

New Forest, New telephoto lens, new pics...
Some pics from the New Forest. I was intending to shoot some video but never got around to it. I was a little dissapointed with my results considering the location and the light, oh well can always try again next weekend.(some pics from Kingston riverside also tacked on)
