This new manual Laowa 100 mm f/2.8 2x Ultra Macro APO has no equivalent on the market.
The Chinese producer once again is ahead of its competitors with this new lens. Manual, 100 mm focal length might conquer hearts of dental photographers.
Few sample photos provided by Laowa:
The full macro
The lens has – as many others – 100 mm focal length and f/2.8 max. aperture, but its 2:1 magnification ratio (while photographing from a 24.7 cm distance) is the distinctive value. What’s more, its dimensions are 75 x 125 mm and it weighs 683 g, identical as rivals with only 1:1 magnification.
The apochromatic optical system, based on 12 lenses in 10 groups, eliminates the chromatic aberration. The producer promises also an outstanding sharpness and radiopacity.
Depending on the system, the lens will have various numbers of aperture blades: Canon EF – 9, Nikon F – 7, Sony E – 13. Mirrorless users will be able to appreciate a „soapy” blur of sharpness. The most comfortable version is the one for Canon, with an EF bayonet and equipped with contacts, making it possible to control the aperture from the camera and moving full EXIF data.

This flash trigger is not only new. It is also unusual thanks to its button-free handling.
“From time to time something comes along that changes everything, this is one of those rare occasions,” Profoto says. Is it really? Let’s take a closer look!
Connect is a sleek, black, puck-like pod that sits on top of the camera via the hot shoe mount. It has only three settings: auto, manual and off. You can select one of them by turning the top of Connect to one of three positions. And that’s it!
Auto mode is as easy as it can be. While pressing the camera’s shutter, the correct flash exposure is automatically calculated.
In manual mode you have bigger control over your flash. Connect connects to Connect app via bluetooth. There you can adjust the power of your flash as you wish.
The button-free handling seems convenient and this is what we are looking for when it comes to dental photography.
The Profoto Connect operates on the 2.4GHz frequency and can control any Profoto AirTTL flash with an operating range of 330 to 1000 feet. It features 8 channels and a 30-hour battery life with its rechargeable battery. What’s clever, the trigger turns off automatically after an hour of inactivity.
