Excellent ring flash for dentistry
I have employed my Rebel XT digital SLR into my dental office. I upgraded to the Rebel XTi (10 mpixels) for home. I purchased the Sigma ring flash with a Sigma macro lens for the Canon SLR family. If you look at the Lester Dine website this is basically what they sell for a few hundreds dollars more.I compared the ring flash and lens with the ones offered by Canon and felt that it was worth saving $300 by purchasing the Sigma combo.The macro lens/ring flash work well for dental purposes. After a little experimentation I discovered that I get the best images by using the aperature priority setting. All settings are used with ISO 400 speed. I set the aperature at 14-16 for intraoral shots. This gives the best depth of field. I also use the operatory light for intraoral shots. I set the aperature to 6 for full face shots.I use autofocus but set the ratio to 1:2 to 1:3 for intraoral shots. This keeps the autofocus from "hunting". I frame the...

Sigma EM 140 DG-worth a try
I have been searching the net for a reveiw of this flash. Since I couldn't find one I just went out and purchased one. Yes this flash works iTTL on a D70. I would have given it 5 stars if it had a more robust hot shoe like the SB 600 or DX 50 both Nikon flashes I own. (I have a Nikon SB 21 and it's hot shoe has worn out being the all plastic as well) . Other than this negative this product seems very well built and sturdy. The flash is permanently attached to the control head unlike the Nikon ring flash which was in 2 parts. This makes stowage a litte difficult in your camera bag however it does come supplied with it's own very nice ballastic nylon bag. Unlike the Nikon the cable is spring coiled and always stays neatly out of the way. It is a good sturdy and well reinforced cable. It's controls are fairly simple to figure out. took some pictures today of orchids and the exposures were (mostly) perfect. I put my camera on the full PHD mode (push here dummy) and the EM 140 DG on...

EM 140 DG
Finally a flash Nikon should have produced long ago. I shoot a lot of macro and have used the Nikon SB 29s with my Nikon D100. Unfirtunately that flash forced me to use manual mode as it doesn't know about digital camears. This is fine most of the time, but sometimes you don't have the time to experiment and shoot bracketed series, etc. So I went out and bought this flash.a) Yes, it definitely works fine with Nikon's older D-TTL system besides the newer i-TTL. The D100 uses D-TTL. The D70 i-TTL.b) It is a really nice piece of work.I sold my SB 29s. The LCD panel on the back is not immediately obvious, but once you have flipped through the few pages of the slim handbook (takes about ten minutes). all is clear. The automatic TTL works fine when you're in a rush, like when you are shooting medical operations on the fly or when trying to get that butterfly shot before it flies off. The manual adjustment options are really really worth spending some time...

Works, but limits minimum field of zoom from 18 to 30-35mm
