Mirror! Mirror! -a guide to choosing and using Mirror lenses PART 2

After several years in the making, I have published the second part of my mammoth mirror lens test. This time I have tested the Sigma 600mm f8 in detail and pitched it against the Zeiss Mirotar 500mm f8 and the Canon 100-400mm f4.5-5.6 LIS ll. 

I have also answered some critical questions about the viability of mirror lenses on todays cameras.

Included is a brief test of the the Vivitar 600mm f8 Solid Cat and the Vivitar 500mm f8.

Lightroom Corruption Problem on Import Solved.

Screen-Shot-2016-02-12-at-11.37.49

Yesterday evening when downloading the latest images in my long running Mirror lens test review, I was faced with this as Lightroom corrupted the images after transferring to my MacPro and during the preview build and /or DNG conversion. You can see that the images initially appeared OK but then as the previews built, bizarre lines and colours appeared.

The solution was to delete Lightroom preferences, like this.

Restart Lightroom,

On Mac holding down SHIFT OPTION COMMAND  – or SHIFT ALT COMMAND

Then RESET PREFERENCES.

The problem then is that you have to reset all your preferences such as the location of cache, export file format etc. But at least it solved the problem.

Royal Photographic Society International Print Exhibition 2015 and 2015 Biennial

I recently found out that I have had two images selected for the RPS International Print Exhibition, from 5000 entries entered, only 100 were chosen.

See the shortlisted entries here

In addition  image “The Volleyballers” has been selected for the RPS Biennial Exhibition.

All three pictures were taken in my home town, proving that you don’t need to pay thousands of pounds to go to foreign destinations to get international standard images!

Photoshop CS6 Problem with Yosemite and Wacom Tablet

I had a great day photographing the MODS at the annual Brighton MOD Weekender. Previously one of my pictures was chosen by the Brighton Dome as one of the posters for the Club Exhibition.

I then had a frustrating day editing pictures, after I upgraded my MacPro to Yosemite. All sorts of problems with tools like the lasso, quick selection and the cursor disappearing etc. I found out that this is a known problem, and Adobe have created a plugin for it.

10th Anniversary of the Boscastle Flood – 16th August 2014

I was called by the BBC News yesterday to ask if they can use my Boscastle Flood footage again, as it is the 10th anniversary this Saturday! I can’t believe 10 years has passed so quickly – I can remember every aspect of it like it was yesterday – the shock of seeing it, and narrowly missing being swept away in my own car, the soaking wet people in their shorts and T-shirts – (it was unexpected that 3″ or rain would fall in 1 hour), the interview with Sky news and seeing the footage on the 10 o’clock news. (It was the first video I’d ever shot! taken on a Canon Ixus – long before camera phone video capability of course). It was all caused by the bridge in the image below which couldn’t cope with the capacity of water – note it looks like a giant hosepipe, the water had to find an alternative path, so it flooded the car park and the high street, and out went the cars. I left the water droplets on deliberately! Watch out for the videos this weekend, and you can see stills here www.waynegrundy.com/boscastle

Isle of Man TT Race Images

I spent a great 4 days at the Isle of Man TT as a guest of Honda Racing. Here is a link to the photos. It was surprisingly difficult to achieve sharp images as the bikes are travelling very fast and close to you, within a few meters. Fast shutter speeds are required with small apertures, as so little of the bike would be in focus otherwise. This lead inevitably to high ISO’s (up to 3200) in the sections under the trees, such as at Ramsey.
