The Sigma is one of my favourite legacy lenses. The copy I have is in PK mount, and I use it with a K&F adapter. These are a couple I took on a recent motorbike trip to Scotland, on which the Sigma ended up being the only lens I used.

On Dec 24th I shot the Full Moon from Marco Island using my Sony A7R M2 and a new Tamron 150-600 mm lens with Sigma EX 2X teleconverter mounted using Sony LAE3 adapter. The RAW shot was taken on a good tripod using ir remote trigger, ISO 64, 1/13 second, f13 (essentially the most open possible), and manual focus, stabilization turned off and on for subsequent shots. At 1200 effective mm the moon filled something less than half of the short dimension of the frame. I processed in Lightroom and Photoshop with limited optimization, mostly increased contrast and clarity, and moderate smart sharpen, although I did use lens correction which eliminated most of the chromatic aberration. I cropped the photo so that limited black surrounded the moon, final jpg size was 2.4 MB; the uploaded photo is 800kb, JPG level 10). I set the camera to electronic front curtain shutter but did not use full electronic shutter option. I did not see a significant difference when I shot with and without in-camera image stabilization. I had separately tested the TAMRON lens when bought and it was not nearly as fine detailed or contrasty as my SONY 70-400 mm G lens but it was still pretty good, particularly at f11-14. Use of the teleconverter did not degrade the TAMRON as much as for the better Sony lens, which might be expected.

Hi everyone, I published a few days ago on my blog a long list of 35mm legacy lenses. I had this list for years, and finally got to clean it up a bit to make it comprehensible to others and not just me I'll try to keep it updated, so come back every few months if the lens you want is not there. You can check it - and download a copy for personal use, if you want - at: 35mm legacy lenses: sizes and specs Careful, the list is 2,5Mb, so the page will take quite a bit to load! And if you're interested at the following url you can learn how the idea was born (not my site, I was a guest on this particular occasion): How the 35mm legacy lenses list was born: a guest post at DearSusan In a bit I should be able to publish another one about medium format legacy lenses, if anyone is interested, so stay tuned. Happy pictures
