OK, so nowhere as easy as I thought it would b, but an important learning experience
Tower Bridge was the wrong bridge - the traffic is too slow for a start.
There are traffic lights 50mt down the road so the traffic flow was irregular, or just one side at a time.
Too many tourists
Shake reduction was off and I used the 2 sec timer, but the bridge was moving a fair bit with the traffic..
All good experience though, didn't really get any usable shots, but I didn't touch my auto setting so Im more than happy :-)
Im also confused - Im going to show some pictures to show what I mean.
First one with the DA 35mm F2.4 plastic fantastic
ISO 100, 20secs@F18, no flash, WB=auto
Then we have the DA 12-24
24mm, 4 secs @ F13, ISO 100
If I try to find one around the F18 mark, I can get this
24mm 6secs @ F18, ISO 100, tripod WB=Auto
All shots were with a tripod, I remember my 35mm performing a lot better than the 12-24, I would get a shot with the 35mm, think the exposure was right and then change to the 12-24 and try the exact same settings and I would get a horrible over-exposed mess, I spent 90% of my time with the 12-24 at F20 or F22.
I am right in thinking that if a lens is correctly exposed when stopped down, I should get a similar exposure if I use the same settings when I switch?
This was probably the best exposure I got out of the 12-24
21mm 2secs @F22!!! ISO100, WB=auto
I seem to have a major issue with over-exposure on the 12-24? I did check the lens was on correctly!
What is going on - do I need to take the lens in for a check up
