1) Ok, offering this here before putting it elsewhere so speak up if interested!
This is a great value for money lens that I am reluctant to sell but I'd rather convert the value into something like a Canon G11 compact. This is a constant f2.8 aperture lens that has been very lucky for me having won competitions or been placed several times with images using this. However, last summer I upgraded to the Nikon 28-70 f2.8 to go with my D700 at 3 times the price of this.
It works great on a DX camera, very sharp after about f4, and I used it regularly on my D300. On the D700 it performs very well and is a popular lens but, as you would expect, there is nothing to match the Nikon 24-70 or 28-70. For those you will pay £650 - £1000 secondhand.
Lens is in very good condition/excellent -. Optically excellent and has the Sigma rubberised finish. There is just a little dulling and buffering of this finish but it is very minor, looks good and comes with it's Sigma EX case and box.
If you are interested, it's £260 inc. special delivery.
I'm going to advertise it elsewhere in a day or so. Alternative is collect from Leicestershire.
2) Flash triggers: Also have a set of remote flash triggers made by ishoot/SLRkit. This is a hotshoe mounted trigger unit and 3 flash shoes. These are really for Canon with the dedicated shoes, but will trigger Nikon/generic flashes. You can have the whole lot sent at £22 recorded delivery.
Not messing around, these are the prices and competitive to anywhere else, better than Ebay, so let me know if you are interested.
