Was it worth upgrading and paying the extra money???
A most definite YES. Although there was nothing wrong with my Nikon 28-70mm lens, this new 24-70mm lens is by far a newer design and brings together newer technology including the coating used on the glass. The focus speed is quicker and it feels more precise. I am very impressed with it.
Incidentally I sold my Nikon 28-70mm to another professional photographer through eBay who had all his camera equipment stolen and had not been insured. There are a lot of photographers out there to choose from and I would say that quite a significant proportion are unlikely to have insurance. If they are not willing to pay for insurance to cover their equipment then there is the likelihood that they will not be insured to photograph your wedding. I personally pay a lot of money for the most comprehensive professional indemnity, and public liability insurance, as well as camera equipment and portfolio insurance (arranged through Alan Beardmore at A1 Insurance Services in Wetherby). It costs a lot of money each year but I need to ensure that I am covered for every eventuality including someone falling and tripping over my tripod at a wedding. My insurance company dictate various terms & conditions I need to have in my contract with my clients in order to cover me, and there are a very small number of venues who specifically ask for proof of insurance before I am allowed to photograph a wedding at their venue. I arranged it through Alan at A1 as I told him specifically what I wanted it to cover and he was able to sort out exactly what I wanted.
If you are looking for a professional photographer you should always check they have the appropriate insurance, just in case…
