Flash for Canon 60mm lens

[davholla13]

I like my Canon 60mm lens and for most photos I am happy using the pop up flash. Although it could be better it is a good compromise with ease of use.

Please bear in mind that all my photos are aimed to make me good at taking photos when I am in the cloud forest when I go to Colombia on holiday and so techniques must not be too difficult to use in the field and carry in a backpack. Although I want my photos I take here in the UK to be good, that is a secondary aim

(I am a big fan of itchydogimages and I like the black backrounds that I often get, like he does, I know some people hate this and I like their photos too which is strange.)

However for beetles I don't like the effect. Any ideas?
