The sharpness is much better than most of my old SLR lenses which is more than enough for me. At this distance, around 1.5m, the depth of field is large enough to keep the subject fully in focus. Given a greater distance between subject and background, the separation would be very clear.

This is the third and final of my automatic lenses – it’s also a very popular one. The 50mm focal length is very versatile and can be used for most “walk-around” shots, portraits, home photos and even travel shots. The large aperture makes it great for pictures and filming in low light too. Its also…

Another way to utilise the spherical bokeh patterns is to enhance the perspective. The leading lines in the background are aided by the angle of the bokeh on that side of the photo.

Here you can see that the focus is very odd – the image looks like it’s been distorted by some sort of glass orb – a similar swirl of bokeh to the old and gloruous Petzval lenses.

This is a pretty good example of the skewed focus plane of this lens. If you look at the sharpness of the trees on the far right, you can see they’re more in focus than the trees in the middle of the frame. does a great job of separating subjects from background while maintaining detail…

The wide angle distortion is quite pleasing and the vignetting helps focus on the middle of the frame. There is however a lot of chromatic aberration around the edges if you care about that sort of thing.

This is a very quirky lens. Quite hazy and vignetted, great bokeh at a wide angle and pretty sharp at small apertures. The most interesting feature is definitely the focus plane. Originally a Pentax mount i think but the adapter is slim enough for use with EF cameras.

A similar story here to yesterday’s sample but this one was taken in indirect light, making it a lot softer. Bounced light looks really good through this lens.

The one odd thing about the lens is that it tends to dull green light. Here you can see that the sky is unnaturally blue and the rose is red hot but the leaves have a dull, murky green colour and the lighting almost gives the impression of a solar eclipse, very harsh but pale…
