Picked this lens up last night. Woke up around 4am this morning with toothache, so thought i'd get up and go into the local towncentre and give it a bit of a test drive while there was no-one around

Few things I've noticed, I need to start using a timer or dig out my remote release on long exposures, and this lens is a bit more of a beast than I gave it credit for.

Sure I'll get the hang of it....

Well, I quite like your first results.

Sure you've got a learning curve, but I think you'll soon get into it. I use a 10.5mm from time to time - and always surprise myself with the odd OK image, otherwise I use the 17mm end of a zoom quite a lot, but can't justify anything in the 11-16mm range as being useful.

I think your major shock/issues will be when you come to cope with flare in bright daylight conditions - just don't be put off! Work with it!

I found with mine that its very important to hold the camera level as otherwise you get massive convergence of verticals. Also important to pay attention to straight lines in the composition so that they look right. Otherwise this type of lens really emphasises any oddness to the perspective which is fine if you are going for it intentionally. Not sure if this was the case with the ferris wheel shot though?

I'll go a stage further with that and say this lens isnt forgiving to bad composition as much as say the 18-55 where you can crop bits and pieces.

The wheel pic was taken on a tripod standing maybe a foot tall on a slight decline and had to be more or less at that position otherwise the third more distant pole would be too far into the middle of the wheel

I've got some colliery ones from today that I'll put up a bit later that have a really strange perspective.

Dont get me wrong, I'm very impressed with what can be done with the 10-20, but it's not a "snapper"

OK, time for some more. I was amazed at what this lens does in daylight to skies



Someone mentioned flare. I dont remember seeing a rainbow when I took this frown

That looks more like a hair on the sensor.

Was a hair or something on the sensor, found the same thing on another one

Anyway, still having fun with this new lens. Perspective is a new word for me smile

Have to be really careful with angles and lines, and er...I wasnt

I like the first shot in your original post, been thinking about going into town to try something similar to that with that statue, and maybe the miner oposite rileys too.

Good call. It's fun trying to dodge the CCTV cameras first thing as well

Check out Bolsover Castle too, but take something or someone with you to photograph in some of the rooms. This was one of my favourites

The Tokina is f2.8 is it not? Which would perhaps add to its flexibility, but I've got the Sigma and it spends a huge amount of time on my lens.

Brilliant shots there John smile

I'm struggling with this supposed hair on sensor thing, I think it's a characteristic of the lens as I've cleaned the camera out a few times.

It's noticeable here



Same spot, same line. There's nothing in the viewfinder when I look at it other than a bit of dust

Might have a look at one of those lens pen/SensorKlear things, it's only a D80 so not worth sending off for a specialist clean

I hope you don't mind but I had a play.

I agree that you've got some dust on the sensor, but the dark band looks like the shape of a curve not unlike an internal surface of the lens.

I haven't tried to lose all the flare, but thought the sky could be improved, along with the contrast generally:
