Robin Red Breast

It must be apparent by now that I'm having a fad on Blipping birds;  I  used to think I wasn't interested in shooting wildlife, but if I'm honest it was probably because they wouldn't stay put long enough for me to get a shot.

Out of the 100 or so frames that I usually take,  I generally have about 6 which are decent, so  I think I need to start saving for a fast lens.   I'm told what I need is a prime 300 or 500 2.8.   -   of course I do, it's just that it will cost an arm and a leg.
