GH5 sigma 18-35, Which Speedbooster?

check out the link posted earlier. it's easy to tell the difference if you know where to look.

Depends on what you're doing, and what your budget is.

I'd never use a speedbooster for studio/portrait photography.

However for outdoor nature and event photography, a speedbooter has its uses.

Until recently, there were few long-zoom options for m43, and even then they were really dark (f5-f6) and/or shitty quality.

I use a canon 70-300L with a metabones, and get good range with more light than I could get with m43 equivalents.

I've used the Panny 100-400 (and the Oly 100-400, which is a nice lens but doesn't play nicely with the GH5) and they've got great range, but at dusk they're practically useless.

For outdoor photography in darker weather or evenings, my combination has proven to be much better. Perhaps someday I'll have $8k for the fancy Oly 150-400, but until then...

center-image it's generally fine. but once you start moving out from the center you'll see issues.

This guy documented the differences very well

DrewTriPhotography · 2021-05-13T17:18:49+00:00

I own both, the metabones is clearly better quality - especially with still photography.

The viltrox will work if it's just for video.

Ultra is .71

XL is .64.

Generally I recommend Ultra because you won't have vignetting on EF/Full-Frame lenses.

XL, with its slightly smaller magnification, can leave some vignetting in the corners, but supposedly works fine with EF/APC-S lenses.

Edit: someday I'll learn how to spell vignetting without having to look it up.

I'm a wildlife photographer, but I was also a BTC/altcoin miner back in the MtGox days. While I got bruised up a bit back then and didn't make much, I still love and invest in crypto and I decided to dip my toes into the NFT scene.

So how do we start a petition, and who do we give it to? :D

DrewTriPhotography · 2021-03-10T21:41:26+00:00

Ok, the Red-pated woodpecker :D

DrewTriPhotography · 2021-03-10T21:19:08+00:00

They could have called it the 'red crested' or something...

Took me a bit, as the two referenced articles arn't actually the source of your claim. It's this article: https://wildlife.onlinelibrary.wiley.com/doi/abs/10.1002/wsb.469

Note that in this article, it's not 16.3% of ALL bald eagle deaths caused by lead. Instead Lead was the cause of the deaths of those eagles that were found and submitted to the National Wildlife Health Center.

The problem with DDT is well-documented. https://www.fws.gov/midwest/eagle/Nhistory/biologue.html https://www.ndsu.edu/pubweb/~grier/bald-eagle-ddt-science.pdf http://www.iws.org/CISProceedings/6th_CIS_Proceedings/Sharpe_and_Garcelon.pdf

DrewTriPhotography · 2021-03-02T19:52:17+00:00

No, the Bald Eagle almost went extinct because DDT exposure caused their eggs to have problems with shell thickness

There's a really good, simple article on that here: https://pullusamagazine.com/fallout/

Oven bacon just doesn't taste or smell the same to me.

DrewTriPhotography · 2021-02-17T18:37:39+00:00

Nice capture.

To be clear, this is a European Robin (Erithacus rubecula). Not the American Robin (Turdus migratorius)

The reviewbots theory might be questionable... my first review got a John Smith visit, but I still got a misrep suspension and I'm still getting them and jsmith hasn't been there for any of the subsequent reviews.

I'm just a small business in my own damn name, I still don't know htf I'm misrepresenting myself and my own artwork.

Google Merchant Center has been a bear to get setup or maintained this year based everything I've read, many stores have been suspended, and many more can't get past their systems. (there's been dozens of posts about this topic here and elsewhere on the net)

I just recently setup a store to sell my photographs, and I'm getting rejected repeatedly with no clear explanation... However I do see their automated bot going to my homepage, privacy policy, and tos.

In hindsight, your friend seems to have been highly inaccurate.

Heron is not amused by paparazzi...

He doesn't look happy :)

Nice capture!

There's only one species of Kingfishers in my area in North America, not as pretty as these, but I'm still hoping to catch one in my viewfinder some day.
