Sony 500mm Mirror AF lens

Sony does have an interesting lineup of lenses. Some of these lenses have special abilities with no equivalent amongst the other manufacturer’s lens lineup. One of these is the Sony 500mm F8 mirror autofocus lens. This is the most compact and lightweight 500mm autofocus lens available.

Review: Sony A7R and Coastal Optics 60mm F4 APO Macro

The Coastal Optics 60mm F4 Apo Macro lens is a truly amazing optical engineering feat. It is apochromatic from ultraviolet, visible light, through to infrared. This means that the light from all three spectral range will be focused at the same point, so the image remains nice and sharply focused; bear in mind it is supposed to let through a significant amount of the UV, unlike other apochromatic lenses.

It is the only such lens I know of which is still in production with such an apochromatic capability – even the UV Nikkor 105mm F4.5 has no focus shift for UV and visible light (but not infrared). The Coastal Optics is also said to be very sharp from wide open. But it does have its weakness (the hotspot issue), although that can be overcome through various ways – I will talk about this later Continue reading Review: Sony A7R and Coastal Optics 60mm F4 APO Macro

Sony A6000 – Picture Effect+ App

I was in the park today shooting the flowers in UV and Insect-D-sight, but had also brought along my Sony A6000 and FE 70-200/4 OSS lens.

Hence I decided to try a few of the picture effects available through the Picture Effect+ App, which is free to download via the Playmemories App. There are a total of 13 effects: Partial colour, HC B+W, Soft focus, HDR Painting, Rich B+W, Miniature+, Watercolor, Illustration, Toy camera+, Pop colour, Posterization, Retro photo and Soft High-Key+.

There are times when shooting macro where you will need that extra bit of extension – for me that would be when doing extreme close-up UV-induced visible fluorescence (UVIVF).

Hence I have been building a kit to use with my Olympus EM-5 and the Coastal Optics 60mm F4 APO in Nikon F-mount, when my focusing helicoid will not get me close enough. Continue reading BPM Bellows
