There's more: back-illuminated CMOS sensor, six-blade lens aperture capable of producing bokeh effects, direct-to-DVD burning, zoom microphone, and expandability via Memory Stick cards (no SD cards or other similarly popular formats, unfortunately).
Plucked hair was placed on clean glass plate and a bulb was cut off with a clean and sharp razor blade under a magnify lens.
Containing a six-blade aperture, the G lens produces beautifully defocused backgrounds with a soft, natural feel.
Tumour tissue was microdissected with surgical blades under a binocular lens at a ×50 magnification, and digested in 100 μl buffer containing 200 μg ml−1 proteinase K overnight at 37°C.
The 50mm f1.4 EX DG HSM has an aspherical lens, nine rounded blades and promises fast and quiet AF.
These will either have the same number of points as your lens has aperture blades (if you have an even number of them), or twice as many (if you have an odd number of aperture blades).[3] Stopping down to small apertures will give you these little sunstars.
These will either have the same number of points as your lens has aperture blades (if you have an even number of them), due to overlapping of opposite-sides' spikes, or twice as many (if you have an odd number of aperture blades).
Watch for sticky aperture blades; the oil coating aperture blades will gel together if the lens has not been serviced regularly and this will make them sticky.
After the procedure, each eye was cut horizontally at the equatorial region using a razor-blade, and a picture of the lens capsule was taken using fluorescent microscopy (SteREO Lumar V12, Zeiss, Jena, Germany).
Soft-edged at the widest aperture, due to the perfectly round hole (the edge of a lens, rather than an iris blade).
The process involves a small, bright light source, precisely placed lenses, a curved mirror, a razor blade that blocks part of the light beam and other tools that make it possible to see and photograph disturbances in the air.
