It seemed such a simple task. Take close up shots of two vintage lenses that had kindly been gifted to me. I needed to know which mount they were on to buy the right adaptor to use on my Sony a6000. I would post the images to a FB vintage lens site where I know I would get the right answer.
Here is my first effort. I was using a wide angle lens the Sony 10-18 mm as it was already on my camera:
f/4, 1/500 sec, ISO 1000, Shutter priority, 18mm
Not sharp enough so I tried again:
Still no good
I decided to give the other lens a try:
f/4, 1/30 sec, ISO 4000, AV mode ,30mm now using the Sigma 30mm 1.4 lens . It is so bright because of the high ISO. Still not sharp.
Next try:
Tried increasing the shutter speed to 1/160. By now I am getting exasperated with myself.
On the 10th attempt finally common sense clicked in. I increased the f stop to f8, lowered the shutter speed to 1/160, kept the ISO at 4000, and used the Sigma 30mm Prime lens at 30mm.
f/4,1/125 sec, ISO4000, 30mm, AV mode.
I am not sure why this image works at the lower f-stop, but by now I was past caring!
The lesson here is to not be afraid to increase the f stop and ISO, and to prioritise both over the shutter speed.
The end result was they were identifiable on FB and within minutes of posting I was told they were Canon FD mounts, so now I can buy the right adaptor for my Sony!
indoor photography is clearly more challenging, as my previous blog post amply demonstrates. However I will continue to experiment with indoor shots in case I ever get interested in still life photography.
