![]() If your current lens will not focus close enough to make a subject larger in the frame, it is time to get a macro lens. What is the ultimate Sony FE (full-frame, E-mount) Macro lens?

No. Kind of counter-intuitive until you think about how the lens reversal works with the light rays. BTW - when reversing a lens a wide angle lens gives higher magnification than a tele lens. The E-mount lenses are probably not a good choice because their rear focusing distance is so short (making the macro subject distance equally short), but if you can get within 1/2 inch you can get good results. Additional lighting is critical via a slaved off-camera flash. So my initial impressions? You need to experiment a lot to get suitable results. This is a cotton print quilting fabric.įinally something organic - from the fridge! A cabbage leaf. No chance to hunt down bugs at the moment, so I looked for some other subjects with colour. The fakes now have it too, but this is an original (I hope!) and a crop from the image: If any of you have one of this famous brand of watch you'll know how difficult it is to see, so a good test. A well known manufacturer lasers a tiny logo coronet at the base of the sapphire front glass (for last 6-8 years). These are out of focus as they are a deeper inside the movement:Ī final test that is always a photographic challenge. ![]() The pink synthetic ruby jewels in the bottom right of frame make up the lever of the escapement - what makes the watch tick. This is the balance wheel with shock assembly and fine adjuster 'swan neck' regulator. This finish is actually surprising good considering it only costs $35, less than a quarter of the Swiss original.Īnother shot of the Seagull. This is a Seagull (Chinese) copy of the Unitas/ETA 6497 movement. The rule graduations are 1/8 inch and the screws are used inside a watch movement. Here's the image I used to get a rough magnification estimate. I work it out to 1.25x on the sensor (21.5 x 14.4mm), so you can get true macro images with this set-up. So what is the actual magnification achievable with this. You can see the bit of focus softness in the corners but no serious chromatic aberration: The bill is a bit worn, but the creases add a bit of character. Of course I had to take a close-up of George. The images are straight from the camera, the JPEG that comes with the RAW. So depending on your monitor size you're seeing a magnification of around 130x. I measured the red filament length (where it crosses between the printed letter) under a loupe at 0.025 (1/40) inch with a precision micrometer. You can see a bit more detail of the interesting coloured filaments visible in the paper at this magnification. Probably a video light would be a good option as you could then try some Macro video!ġ00% crop of above is not too bad considering the extreme magnification. I could roll the shutter open, but too slow in practice. I found that I needed to illuminate the subject with a torch to get an LCD image as the lens shadows the subject. The lens is only 1/2 inch from the subject when in focus, so flash from the SB800 is a bit oblique throwing some shadow contrast. Kept the ISO at 200 and pushed the shutter to 1/160 (the highest sync speed) and slaved a Nikon SB800 to the flash on the NEX. Initial tests fully stopped down to F22 were not great (poor focus), so compromised on F13. The famous Dollar Bill seems a popular, familiar test subject. This is the set up with 16mm E-mount lens attached: Quickly cut a hole in one and threaded in a 55mm filter to give some protection to the rear lens element and to help keep dust out the back housing. So I paid my $12 for the reverse lens adaptor which arrived today with a couple of $3 rear lens caps.
