It was raining outside and I had a couple of hours to spare so did a few comparisons, with a standard macro lens, reversed 28mm and 50mm and some stacking.
All shots straight out of the camera

I agree with Hefty, I have tried this combination with some good results. I made the 52-49mm adapter by glueing 2 old filters together and knocking out the glass.

You can also try a set of bellows heres one on E-bay which looks the goods, you will need a screw mount adapter.

Thanks mate, you have been very helpful, I have just been on the web site and downloaded Trail version 3.4, If it finds the pics I am missing I will have to pay for it before I can save them, so I will see how it goes

If that doesn't work I will try version 4.0. Thanks again

I'm using Rescue pro version 3.2 and it was a 4gig card.
I can't seem to find anything in regards to limits. :

I also downloaded Card recovery 5.20 and had the same problem

I will give Rescue pro 4v0 a shot and see how it goes. Thanks

I goofed up yesterday and accidently deleted 200 pics from my SD card while downloading them to my PC

I immediately quarantined the card and installed the recovery software you get with Sandisk Extreme III cards,

I was sucessfull in recovering 160 of the pics, but for some weird reason it wasn't sucessfull with the last 40 shots on the card. It will show the missing pics in thumbnail form at 65kbs per pic, but not at thier original size: When I click on the thumbnail it just shows a greyed out frame.

I paid for and downloaded another recovery program from the web, but got the exact same result. All the missing shots were taken at the same time in an old time Pub in Alice Springs. (live snakes and spiders crawling around) So its kinda weird that it will recover all the shots up to this point and then fail :: Any Ideas :

I just haven't got around to it yet

Wow, excellent shots, and with a 500mm lens

Matt, you still need to permit use of the aperture ring in the custom setting on the A series lenses or you will just get the F-- flashing ??

Sounds to me that the 28mm you have bought maybe faulty. As Matt says its not contacting with the body properly so give the lens mount a good clean and try again.

EDIT: the A series lenses will always ask for the focal length, thats normal

I wish I had your restraint Mike I would have bought it for sure, I am always doing it, buying gear on impulse and reselling it

I have the auto power off set to only a couple of mins, if I am carrying it around its just a half press on the shutter to bring it back to life.
But I turn it off if I am not using it, and its back in the bag.
