Re: Replacement adapter rings for 1200 Macro Flash?

Excellent, thank you for answering both questions! I shoot with the a99, so not APSC. I'm not sure if the 49-55 will have an effect on the photo with fullframe. I'll have to run a test. but I didn't think about the step down on the other side and then use what I have. Thanks for that!
Using a stepdown adapter would only cause vignetting when fitted for distance focussing , i.e , probably from over ten feet to infinity .
Which you won't be using a macro flash with anyway at that distance .
In macro as you focus closer the the lens moves away from the sensor ( unless it's an internal focus one ) and the image that is projected back is spread out further , so much of the projected image is unused .
If you want to see this , if you have a lens with a manual aperture , say a 50mm lens , hold it facing a bright window , 1" away from some white paper and you'll see an image say 1 1/2" diameter .
Now do the same holding it 3" away from the paper , the projected image will be about 3" diameter , but you sensor stays the same size .
So vignetting ? no problem .
and also about the 1200AF. Good to know they are both compatible. That might be an option to have one as a backup. Not sure how long these things last. Still, the step down ring might be the easiest to try right now.
Have a great day!
They last a long time .
I bought one in the late 1990's to go with my Minolta 7000AF , and still have it , works fine .
When I went digital with the Sony a100 in 2006 I needed a new macro flash and got a Centon branded one .
I finally got Minolta MFC-1000 and ring flash to use on it .
Then I got a Sony one with the twin flash set up that works with the Minolta , but doesn't have the socket for the ringflash .
A few years ago ago i got another Minolta MFC-1000 with ringflash for a silly price off ebay .
Someone was selling a Minolta DiMage 7 for £29 or make an offer .
I didn't waste any time making an offer , I just got it bought !
the camera on it's own was worth that .
The main cameras I'm using now are the Sony a900 and a77ii , the macro lenses I use are the Sony 100mm and a Minolta 50mm f/3.5 , which is probably one of my favourite lenses .
I also have a sigma 180mm f/3.5 macro , but that works best with an on board flash and diffuser .
The flash works well with all of them ( except the big Sigma ) .
