Digital:

main camera/DSLR:

Canon 400D + kit lens
opteka 0.2 fish eye adapter
50mm f1.8
85mm f1.8
Tamron 17-50 f2.8  (to replace kit lens)
Nissin Di622 Speed Light


compact - Ixus 120 IS - useful for taking snaps on a night out - has image stabilisation (useful in low light) & fits in pocket

Film Cameras:

for fun stuff - (recently took to a festival)

Diana F+ Black Jack
Fish Eye Lens for the Diana F+

and just arrived today from an e-bay seller in the Ukraine:

Zorki 4 camera
50mm f2 Jupiter 8 Lens
135mm f4 Jupiter 11 lens

Thought Id try using a rangefinder camera though rather than drop a grand on a Leica and some Zeiss Lenses I went for a £30 Russian copy and some KMZ Lenses that are basically exact copies of the Zeiss Sonar lenses.

Looking to add next:

Some vivitar 285 flashes (probably 2 or 3), couple of lighting stands/umbrellas and some e-bay triggers.

and maybe later on:

Sigma 30mm f1.4
a 70 - 200_or so telephoto zoom - preferably f2.8 so likely a Sigma
A new Camera body - perhaps the 60D when it comes out
