 Butterfly photography again

Years back I published a post on the Canon 55-250mm EFS as a budget friendly butterfly lens on my Canon APS-C bodies.  Times have moved on, I now use Olympus/OM Systems micro 4/3 equipment, and a recent day at The Garden House when I managed to capture these male and female Orange Tip butterflies (Anthocharis cardamines) feeding on Sweet Rocket, Hesperis matronalis, reminded me of how I now use my Olympus 40-150mm f2.8 PRO and 1.4 x teleconverter as my go to combination for shooting these flying flowers.

The native lens has a minimum focusing distance of 0.7m - just over 2 ft - and a magnification at 150mm of 0.21x. By adding the 1.4x teleconverter the minimum focusing distance stays the same but the magnification increases at the now 210mm end to 0.3, allowing tighter framing.  This is the difference:

150mm on native lens

210mm on native lens + 1.4x teleconverter

Effectively I have the equivalent in full frame terms of a close focusing 100-400mm f4 zoom (actually 112-420mm if you need to quibble).  All with Olympus / OM systems PRO image quality and rugged weatherproof build.  Any compromise in image quality from adding the teleconverter is hardly noticeable.  Yes it's a little heavier than my previous Canon 80D/55-250mm combination but the results are far better.

As I've referenced in previous posts, the combination on the OM-1 it also effectively supports hand held focus stacking.  So a five image stack with a compliant subject such as this Green-veined white butterfly (Pieris napi) provides me with both greater depth of field on the subject and even better background blur and separation than the f9 aperture I was using for the previous shots.

In the field this combination of relatively light weight, great stabilisation with the Olympus/OM System IBIS, close focusing to throw more pixels on the subject while keeping a good working distance, handheld stacking and excellent image quality means that I have far more flexibility when pursuing butterflies in their habitat.  As demonstrated by these few shots from previous years

So, a combination that's yielding excellent results in a compact and relatively lightweight package, and, just as importantly, within my budget.  Yes I might lust after the new 50-200mm f2.8 PRO but that's way beyond what I can earn from my image sales - and that sets the budget.
