Bosque del Apache is a sanctuary for migratory birds that overwinter in New Mexico. Still, it wasn't warm there though most of the time while I was there, it was around freezing temperatures. Mostly sandhill cranes and snow geese visit that place on an annual basis and they are coming from colder regions and some from Canada. You can judge the avian population there during the season.... You don't need a long lens for these .
Well I did almost the same tour in Rome city center almost exactly one year after the previuos one (early December). Same subjects, same weather conditions.
So I thought you guys might be interested in a comparison between lenses.
First is Sony Zeiss 35/2,8 second is Zeiss Milvus 50

Damn these lenshoods on the loxia lenses
is so bad that Zeiss can not make it better so they sit more firmly
Yes, hoods and caps, both suck. My Loxia 25 hood is quite OK, but for Loxia 50 & 85 I have dropped the hoods many times.
I don't know how people do photo processing right after shoots. I have been slowly progressing through 2018, got bored and for "change" I'm slowly progressing 2017 photos... Few from 2017 July

Playing with the Vario-Sonnar 100-300 + B&W ND .6
(Detail in these is really lost unless you're zoomed in - but then it's all detail and no perspective)

Exquisite images, Manuel! Is that your new toy ? Any of the images above taken with the A7r in it?
Thank you Joshua, no... it happens you visit Val d'Orcia in a winter Sunday in December at 6.30am and you find a group of 20 people lined up with tripods and cameras waiting for sunrise One of them, probably the organizer, suddenly (for me) switched on and drove up this drone behind me so it is an action grab taken with my second camera.
First three has been taken with my old A7r with Zony 55 and the last one with my more recent A7r2 with G 70-200.
@Ronny Olsson: thank you very much Ronny... your last landscapes are stunning

Samuli, do you use a custom profile or app to correct corners on the G21? I noticed you still shoot it!
I started coding program for this purpose, but after 30-40 hours of coding I gave up and admitted to myself that Capture One LCC (Lens Cast Correction) is good enough for the purpose, and it just doesn't make sense to invest more time for perfect tool for this purpose. In order to make LCC better it would need to have adjustable averaging size and few other features. Now some scenes require additional manual corrections (CaptureOne layers with gradient masks usually, sometimes subtracting from gradient some areas etc.) because coror correction isn't perfect - partly it's not perfect because I have not found perfect opaque white material to create LCC images.
Generally it would be best to use G21 and G28 with backlit CMOS cameras (at least A7r mkII has backlit CMOS, and I would assume A7r mkIII as well, but don't know, I have 5 pcs A7, not needing any new ones...). However I like G28 much better with Kolari modified camera and weaker front lens, and all my Kolari modifed thin filter cameras are with normal CMOS -> color cast and vignetting is bad, and I have to deal with it when I shoot with G21&G28 (and ZM25).

Thanks. I have noticed some wonkiness too with my g28 and g21. I am toying with the idea of picking up an z7 for the thinner stack and then picking up a weaker PCX for the g21. I shoot an a7r2, so color cast for me isn't as bad as you. I just don't know what strength of PCX I'd need for optimal z7 performance on the g21. I could message Haruto(?) and ask him to run it in his optical simulations to ascertain, like he did on the a7 series to start the whole PCX thing.
What are you seeing with a thinner stack + weaker PCX versus normal stack + stronger PCX that you like better?

With Z7 you need 2000mm, as far as I understood Z6/Z7 have similiar sensor cover glass (well, whole sensor stack matters, not just cover glass) what my Kolari v2 has. I did buy all the OptoSigma lenses to experiment with various rangefinder lenses and I found that for Kolari v2 2000mm or 2500mm are best for G21&G28.

With standard stack you need stronger correction filter in order to correct corners properly. Due to this there is too much correction or something else what bothers me in mid-zone - it bothers only in boke scenes. To me the difference is larger with G28 than with G21, but also I don't do much boke shooting with G21...
If I would need 21mm more I would most likely get Loxia 21. However 21mm is so giganticly wide that it's needed like once a year, so I'm fine with G21 and ZE21.
