Few years ago I started  taken  these slides with Canon equipements and  for this web site  I  scanned  then in low resolution.
For this web site  numeric pictures are around 100 times lighter/lower  than the original high resolution  images saved in  "Raw  D.N.G." files.
This year I use a PENTAX K20 and 3 excellents PENTAX  lenses a macro 35mm 2,8 one 16/50mm 2,8 SMC DA and a 200mm 2,8 SMC DA
