Brown Argus is fairly common in the dune systems in Cornwall, especially where there is associated damp grass. This individual was photo'd at Perranporth, though Gwithian can also be good for this species in May and June, then a second brood again in August and September. This is the first weekend that I have been able to photo butterflies properly as for once, there is no wind ! I took this shot with the 300mm lens only, (no converter) on a tripod. Depth of field was quite low at F/6.3 and this should really have been higher, but at the time it was not bright sunlight and the shutter speed required increasing. The ideal is around F/8 or F/10.
