Does a Viewfinder Magnifier help at all? I started many years ago with my dad's old Spotmatic, so I'm not unfamiliar with manual focus, and I also do a lot of glassing with binoculars and a spotting scope.

Do you mean the O-ME53? I have one installed on my K-3 II and K-70. It's helpful for manual focusing, although (for me) it makes it difficult to see the edges of the frame while looking through the OVF.

I started with an Asahi Pentax S. The original Spotmatic microprism screen was, IMHO, about the easiest/best manual focusing system. When I got a Pentax LX ASAP I replaced the doughnut + split-image screen for an all-microprism center. The only modern DSLRs that are as good for manual focusing for me are my current MFT bodies, especially my Olympus EM10 mk II. The focus-peaking assist visible through the viewfinder is exceptionally easy to use.

Yes, it has helped me a lot, particularly with fast lenses. Some other things that help is to do a DOF preview if you're stopping down, and to use the EVF if possible. I occasionally wish for a hybrid-type EVF because although the magnifier helps, it isn't the complete solution.

Hi 300m members !

I am not very active nowadays, but always appreciate all the posts here and in PF threads... nice work!

This is an example of a "missed" photo that has captured a special moment: An underwing that is having a pee in flight!


Sphinx colibri en train de faire pipi en vol / Hummingbird clearwing Having a Pee in Flight [Hemaris thsybe]

I never heard or saw anything like that that before now!

I guess that is because they eat so much nectar, that they would become too heavy, or would "explode" if the excess of water is not evacuated?
I did a search on the Net and I found a link** about that phenomen for the bees. So, that would not be "urine" they eject, but they are rather "voiding water"...
If you have any other interesting reference about that, do not hesitate to share them!

Extract:
"Bees excrete ammonia and uric acid from their Malphigian tubules (insect version of kidneys). It ends up looking more like bird guano than a liquid stream like this. It is sort of dry and can vary in color from white to yellow.

What you are seeing in this photo is a bee voiding water. Voiding water is common in Bumble bees and honey bees as they have a high metabolic water production. Nectar has a high water content which not only provides the sugar necessary for activity but also an excess of water. This excess water needs to be removed in order to maintain a balanced water budget.

It's not urine, so it's not peeing. It's just water."

If we had a Hall of Fame for this thread, you'd be in the first round of inductees, Weevil. Four of the most-liked posts in the top 20, including the all-time #1, which is one of the best images ever posted on this Forum. Great to hear from you.

Unfortunately, the only way I know of to somewhat mitigate the CA is to work on it manually. Sometimes I have to mask certain areas of the photo because I don't want removing CA to damage the subject. This is what I did in the squirrel photo I posted earlier, but I also did not remove some of the CA because removing it proved too destructive.

You can see there is still plenty of the cyan CA remaining, but IMO it doesn't impact the aesthetic of the photo, so I left it alone.

Thanks Luftluss. It's two years since I've been able to get shorebirds there. Last year it was all dried up and this year the water was too deep up until now.
BTW I used the Pentax K-3, DA*300mm and DA 1.4x TC.

Well done.

The image below is a scan from a chrome, a zoo specimen, so it might be something shorter than 300mm (no record or recollection) but I suspect I was using a 300mm f4 APO Macro Sigma

I love the Killdeer shot, but around here it is so rare to see them near water, despite their shorebird ancestry. They are quite the upland creature, nesting in corn and soybean fields, and sometimes large graveled parking lots.
