Re: Macro lens advice

I've done a lot of macro shooting at greater than 1:1 using various, wacky combinations reversed lenses and extension, but for "ordinary" 1:1 shooting, the Sigma EX DG Macro 50mm f2.8 and EX DG Macro 70mm f2.8 are both excellent.

I figure I'm lucky enough to get the "bee" part right! ;)

Thanks! It's a challenging lens to use reversed, but when it works, the results are worth the challenge.

Something floral this way comes

More from the archives. These were taken with a Sigma 50mm f2.8 EX DG macro on a Pentax KP. Apart from a few obvious ones, I don't know many plant names, so you're on your own for IDs. https://live.staticflickr.com/65535/48432069446_4c32dfc5a5_b.jpg https://live.staticflickr.com/65535/48690442818_ac...

Bumblebee (?) portrait and others; now with actual images!

Some items from my archives. All single shots, handheld, taken with a reversed 18-55 kit lens. A bumblebee.

The projected image on the sensor is usually just a small crop of the whole image projected by the reversed lens or the enlarger lens. The smaller the crop, the greater the drop in resolution (in lp/mm). So for example, if you are using a reversed macro lens that was designed for a 35mm sensor, and...

Enlarger lenses vs. camera lenses when reversed?

Hi all; Just wondering what sort of overall differences in performance there might be with lenses in the 24-35mm range between enlarger lenses and SLR camera lenses? I'd be using them for single shots, rather than stacks, reversed on a longer lens, teleconverter, extension tube, or on the camera bod...

Interesting, I've always wondered about these little Pentax lenses, and you tried the fish-eye! The downsized images good, the 100% crops don't hold up but thats okay. Thanks for sharing the results. Robert You're welcome! I was hoping for more, but you can't win 'em all. Next step is to try buildi...

An unexpected optic: reversed Pentax Q 03 Fish-eye

Hi all; Having reversed SLR lenses (prime and zoom), and movie camera lenses for macro shooting, I have wondered, on and off, about reversing the Pentax Q 03 Fish-eye, https://www.pentaxforums.com/lensreviews/Pentax-03-Fish-Eye.html , figuring that its short (3.2mm) focal length would produce even h...

OK, as expected the 17mm is a challenge. There may be more than one version of these, but I have the one with a rather long barrel. Without any added extension, on my Sony A7 I get over 2:1 magnification... With the 35mm I need 6mm extension to reach infinity, so it has a ffd of 24mm. Looking at my...
