Macros with Ring Flash
Posted By: chirpy, 08-23-2008, 10:41 AM

I've added a Pentax DFA 100mm Macro and a Starblitz 1000-Auto Macro-lite to my macro arsenal. The Macro-lite is great fun, especially at under 50 including shipping from China. It does mean manual mode for the ring flash, so adjusting the aperture is a must and is mainly dependent on distance, but I'm starting to get the hang of it.

I also have a step-down ring for my Sigma 180mm Macro which works great with the Macro-lite and doesn't vignette at all (72mm -> 55mm -> ring flash thread).

First, the DFA 100mm:

Second, the Sigma 180mm:

Both photo's are at 1:1 on a K20d with DR enabled.

Hi,

It may be my screen, but isn't the focus on the second one on the grass instead of on the insect?
That is why prefer the first one. Focus is where it should be.

Looks like a ring flash (or is it a permanent light?) is fun to use.

The first shot is great. Is that what many said as flat field with ring light?

Many thanks for the replies. Yes, the ringflash does give quite a flat field as the shadows are softened greatly and I've since found that I need to add more contrast in PP to make the subject stand out more.

I've found it quite useful on the DFA 100mm macro when going to f16 and 1:1 as a hotshoe flash struggles to get enough light into the frame. It does take some time to get used to adjusting the f-stop for the distance of the insect from the lens.

I have to admit that I am tempted by your ring flash. Did you search for a special Pentax compatible one?

No, it's a the generic Starblitz 1000-auto Macro-lite and connects to the K20D via the X-sync socket. This is the guy I bought one from on Ebay:

Those are great. Macro is one of my favorite varieties of photography and I really respect the amount of skill and patience it requires to get shots like those.
