The Nikkor 105mm f/2.8 has a minimum focus distance of about 12-inches which is measured from the camera sensor to the subject so when shooting as close as possible it means that the end of the lens will be quite close to the subject which of course is desirable in capturing those amazingly sharp details. This also means that the illumination of the subject will also be close which is one of several reasons that the diffusion of light is so important.

Secondly, we must remind ourselves that the physical Law of Light tells us that the intensity of the light varies with the square of the distance so when shooting a subject that is further away, more light will be required to obtain the same intensity of light as when the subject is closer.

This is what my rig looked like using Pringles can and the little softbox to provide the off-camera lighting. And hey, who can resist an excuse to buy a can of Pringles?

Getting the diffusion "off-camera" is ideal. Simply meaning that the diffusion mounted on the end of the lens with the Speedlight mounted on the camera shoe works quite well and there are a near endless of ways to accomplish this in both DIY and manufactured diffusion products.

One that works quite well is to use an extension device such as a Pringles Chips can by cutting the end out and smashing it to fit over the flash head. The other end will be at the end of the lens and a simple inexpensive 6X5 softbox works very, very well (I wrapped the Pringles can with duct tape so it would not look as cheesy for I get enough strange looks the way it is).

I cut a Pringles tin at 45 degrees and put a bit of kitchen paper over it as an experiment.
Did a quick garden safari...a bush cricket in a rose, the image has been compressed the original is sharper.
I was pleasantly surprised by the results.

Sippyjug104 is that a 105 or a 200mm in that photo? I have a 105 VR macro and a 105 f/1.4 as well as the "tank like" all metal built 200mm which looks like the lens in your photo.

Regardless... all of these lenses are good performers. I have found the 60mm f/2.8 to also be a very sharp lens. Love that light little beastie.

Today people want diffuse light for macro work, which works if you want to illuminate the cracks and crannies of the subject so that they are not sharp. But depending on how high the magnification is and the textures in the surface of the subject, the image is sharper, the more specular it is. That is, the darker recesses of a surface give it texture, so specular light brings out the little cracks and crannies. (This was known all along for portraiture, using large light sources or light reflected from large surfaces--sharp details of skin cracks were not the goal.)

For very close macro work, when the lens is close to the subject, diffuse light may be the only way to light it up, but the Kodak professional workshop text suggests using tiny pinpoint lights for sharp macro: fiberoptic light sources. This is the exact opposite of circular flash or larger light sources/reflectors/diffusers.

The cover of this book, the little beetle, was photographed on an 8x10 transparency film using a Kodak Ektar 25mm lens for movie cameras (mounted backwards) and pinpoint lights using fiberoptic source. The science of light has not changed.

Real Nikon, this is my Nikkor 200mm f/4 AF ID which is a beast of a lens...physically at 2.5-lbs. I rarely use it now and my 105mm and the 60mm are my most often go-to field lenses.

The 200mm needs more light out at the point of the subject and the law of light tells us that the intensity of light varies with the square of the distance. So...the 200mm provides a very generous reach however the diffused light needs to be increased to send it out to that distance and battery consumption is a factor. It's a great lens for a bright sunny day.

Your 60mm is a great walkabout macro lens, razor-sharp, and comfortable to carry all day.

I've used the "stuffings" of the dividers from old camera bags.

If anyone is interested in some "diffuser" material (much like Nikon diffusers) PM me and we can chat. Glad to help out a hogger.

I've had success with the sides of a plastic Milk Jug, cut to fit.


I've cut out the corner of the bottle leaving one side longer, and taped it onto the pop=up flash units of my cameras. helps a little, when using that harsh little bugger of a light. For a bigger home made job, is a frame, picture to PVC pipe friction joined so you can collapse. Stretch translucent Plastic window covering over the pipes with tape. Shower curtain material hung ahead of a flash on a stand works wonders, and sometimes projects an interesting pattern onto the subject of a background. Also usable as a backlight diffuser. Hang with a friction shower curtain in small spaces.

And if the plastic shheting colored, they open many possibilities.

As I learned in the US Army photo school back in the day Fort Mammoth N.J use tissue paper single or double it up.


Ansel Adams shows that in his book The Camera.

Back in the day, even as far back as bulb, you could drape a linen handkerchief over the flash. Obviously, something more permanent is desirable. Frosted plastic bottles are a good thing to try, find one just the size to slip over and you're most of the way there.


I used to grab a Kleenex from my wife and use it like you used the linen handkerchief.

This is the "off-camera" flash diffuser that I currently use. It's really quite simple to make. I used a piece of stiff bendable electrical wire to hold the shape and then used two layers of vellum tracing paper (later replaced with Rosco Tuff Lux white diffusing paper which is far more durable). I laid the wire that I bent over the paper and folded the edges over and taped them in place. I cut a half-circle notch out to fit over the end of the lens. I can bend the diffuser to close in around the subject or shoot with it flat. Raise or lower the angle as the situation in the field requires.

I'm now using a dual-head macro flash however I have used this with my Nikon SB800 Speedlight and it worked just as well.

The journey is endless so enjoy the ride..!

Sippy, you're a gold mine for those who want to get better. You're like the Britannica Encyclopedia in the old days. Like Wikipedia in our day.

You're photos are great and your advice is also!

Canonclicker, thanks ever so much for the kind reply. One of the great features of the UHH Community is the willingness to share. Regardless of the subject, there is always someone here that has experience in that field.

I've tried so many things to diffuse the illumination of my sessions indoors on my tabletop setup and out in the field that at times a few of them actually work. If sharing my experiences helps others in the slightest way then it gives them something to build on from there.

Most will agree that the best time to be outdoors with a camera is when the lighting is softened by passing through the clouds. The lighting is even and there are no harsh shadows. What would be ideal would be for us to emulate that condition where we are in control of that soft light and need not depend on the sun and clouds.

On that perfect natural lighting day, the CLOUDS actually become the source of light with their glow. The sun is quite far away from our subject, the flower, compared to the clouds above (our off-camera flash). Separating the primary source of light (our Speedlight) from the diffuser on the end of the lens mimics that relationship of the sun, clouds, and the subject. Even more ideal is to have a much larger diffusion (cloud in the sky) compared to the size of the subject. A larger off-camera diffuser provides a larger spread of soft glow which helps subdue specular highlights and loss of detail.

How one accomplishes this and what they may use is endless. Why one wants to do it is with a specific goal in mind.
