Use 67to 52step down to fit canon 100mm macro that works great.

Purchased the Albinar Digital 35mm Slide Copier Duplicator for Canon, Nikon, Pentax, Sony Cameras with 52mm Lens Filter Thread and spent the afternoon working with it. Here are my results:

The equipment used was a Canon 80D with the EFS 18-55mm lens set at 55mm. A Kiwifotos 58mm-52mm Step-down Adapter Ring for Lenses was needed to mount the duplicator to the lens. This set-up on its own did not produce sharp, in focus images. A Ultimax Studio Series MC Digital Closeup +1 filter was needed to produce an adequately sharp image.

For lighting, the instructions state point the camera at a suitable source of light such as the sky, light box etc. I wanted a set-up I could standardize to get reliable results, so I pulled out my old workhorse, a Sunpak 622 super flash unit. Initially I pointed the flash at the unit and ended up with, as other reviewer's have noted, a distinct pattern from the diffusion screen (Photo A). Thinking perhaps adding further diffusion to would help, I put a piece of lens tissue in front of the unit which only added further texture. Perhaps it could be called a "happy mistake" for creating an effect for future images. (Photo B).

The final set up (Photo C), has the flash pointed at a 45° angle along side the camera at foam core. Exposure was ISO 100, 125th at ƒ22. I bracketed the exposure by changing the power of the flash - from 1/128, 1/64, 1/32 and 1/16 power (Photos D, E, F & G).

Using this set-up doesn't quite fill the viewfinder with the slide image, I'm guesstimating it's about 80%. The images I'm showing here have only been cropped with no further corrections made. I selected this image to check both highlight and shadow detail as well as an area with texture provided by the hat.

The final image shown was done using Merge to HDR Pro in Photoshop with editing in Camera Raw and final adjustments and presentation done with Photoshop.

So, bottom line- four stars for this product. It basically does what it says it will and will meet my needs for being able to quickly scan a 35mm transparency for use on the web, dropping in the background of other images or creating montages. Would I use it for making a fine art print from a transparency? No, for that I will still have a professional color lab do the scan.

No matter what I did, I was unable to post the photos in proper order.

I had to buy a 52-55mm ring adapter to mount it on my Sony DSC-HX300, but the results are better than any electronic slide converter I've tried. Your only limitations are the quality of your original slides and your skills using this device with your camera's settings.

I really thought the front of my lens was 52 until I tried to attach this item to the front of my 58mm lens threads. I was angry, thinking I had been duped until I actually measured the duplicator and low and behold it WAS 52. Then I read the inscription on my UV filter and plainly saw 58mm!! I guess I thought that ANY Canon EOS DSLR would have the same size filter threads on its "primary" lens, but this isn't true. Be sure to check your sizes carefully and order an adapter ring if needed. I will update my review after I get the adapter ring I need to make this fit my camera. It looks well made and I suspect it will do the job I want it for (slide duping and perhaps some B&W negatives). My face isn't as red as it was yesterday. Luckily I didn't send the bad review.

Maybe not the equal of a Nikon Cool-Scan, this is a quicker way to go, and if you can get the WB right, really facilitates digitizing one's film collection. Comes ready to go, no batteries req'd, and fits 52mm threads. Easy-Peasy, Sherman! Back to the 'Way-Back' machine!
