The mighty clover
It nitrogenates the soil, it smells fabulous (especially in the Burren where it's so proliferous you can smell it on the air), bees love it and make lovely honey from it. Clover is a top plant. Useful and quite lovely in bloom.
SP 35-80mm f/2.8-3.8 lens arrived today. It is Shaaaaaarp! Unlike the Vivitar Series 1 of very similar spec, there are no reservations here. It'll shoot at all apertures, all focal lengths and deliver.
