Hello! Other than the legions :-( of Haematopota pluvialis females this Tabanid did not attack me... Medium sized (12-14 mm), found two days ago (Ostwestfalen/Germany). Is it Tabanus (bromius?)? Thanks!

Most likely bromius, but can't be sure from this pic Theo |

Hello, Theo! Zeegers wrote: Most likely bromius, but can't be sure from this pic Thanks! Today I have found probably the same individual on the same plant  and have succeeded to make some more pics from different angles. Perhaps I'll post some of them later (after assorting them, I just come from outside having taken many pics again  ).

Confirmed, bromius. Technical question: How do you get this amazing combination of magnification and focal depth ? Theo Zeegers |

Hello, Theo! Zeegers wrote: Confirmed, bromius. Thanks! A beautiful animal! Technical question: How do you get this amazing combination of magnification and focal depth ? Exactly that is mostly my problem  . I must say, that I'm rather a technical dilettant and mostly taking many, many photos with the trial and error method... I use a Raynox M-250 macro lens with a Panasonic DMC-FZ30 digital camera.

Recently I have been using stacked images to get depth of field. Today I experimented with a pinned tabanid Hybomitra zonalis that is a little larger than bromius. Tried to get the same angle. Using a Nikon digital SLR and Nikon's 105mm AF Micro set at f32 gave me results similar to the above. Most lenses lose sharpness at f32 but Nikon's 105 AF micro is corrected for such small apertures; It is sharp enough at f32 for me to be able to see the rows of facets in this tabanid's eyes. Of course, getting such a sharp image in the field with a living fly is far more difficult than what I attempted. So Theo, expensive optics and small apertures is a place to start.

Yes, I know, I need to get the new Nikon Micro 105. This digital photografy is great, but it costs a fortune. Thanks for the encouragement. Theo |
