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+.

Rudbeckia in the park

These are some of the Rudbeckias I saw at the park the other day and just had to come back and shoot them in UV and IDS. If I had a few more hours to spare to wait in between shots for the wind to die down completely, then it would have been feasible to try for lower ISOs. As it is, I shot at ISO 800 and F8, as that was all the weather would allow today.

Gazanias in the park

I had been to the park nearby yesterday, so my daughters can cycle and walk the dog. The park does get different flowers planted into its flower beds each year. This year was the year for Gazanias and Rudbeckias, two of my favourite varieties of flowers.

Hence I decided I needed to go back again to shoot these flowers – I was determined to bring my tripod and not use flash. Hence I was dependent on the wind and weather cooperating with me. Continue reading Gazanias in the park
