I put a Canon adapter on my 30 year old Olympus Zuiko 28mm yesterday; aiming to use it to photograph headstones for my family tree. What surprised me when I tested it was the almost three stops increase in speed it gives over my zoom at 28mm. At f8 I have to use 1/400 of a second compared with 1/60 for the zoom (alternatively I could use a narrower aperture). There is also a difference in colour; the Zuiko needs warming by 1500ºK. Results looks sharper than the zoom but sadly also have a touch of barrel distortion; not a good thing when most headstones have straight sides! I shall give it a try on my next outing to a churchyard.
Super stuff. Visit a must. Ruth
£20 for a mint 400mm f/6.3 Sunagor resulted in a great improvement of my local bird photography --
Great image, and an even better price.

Here's a couple more, from a dull gray, day with little sunlight.
This time using a Pentax Q7 (crop factor 4.7) at 6400 ISO setting, coupled with a Vivitar 300mm f/5.6 prime lens.
I did, but it has made little difference as posted. I use Dfine 2, part of the Nik/Google software package. I just let the software do its own thing. Too much noise reduction definitely can soften an image.

Very nicely and expertly done, guys - thanks for the info. and help.
Normally I use a Fuji X-E1 body with a 400mm Sunagor f/6.3 lens, but for the two above was trying out a recently acquired Pentax Q7 for its 4.7x crop factor, giving me, in effect, a 1400mm lens equivalent using a Vivitar 300mm f/5.6.
The Q7 has a bigger sensor than the early models, it is 7.6mm x 5.7mm, probably no worse than many fixed-lens compacts, and certainly bigger than any Smartphone's sensor.
Lovely job, Philip. I find splitting images into layers a difficult and time consuming task.
