Thank you, Hiep. You are too kind...
Here are 3 images of Hraunfossar, the last waterfall images I will post here from this trip. This waterfall is not as massive as Godafoss or Gullfoss; not even close but it consists of many smallish falls, some cascading, making the overall rendition quite picturesque. Yes, we saw quite a few waterfalls but too many images of waterfalls can get old fast . Finally, a series of images from Iceland is not complete without image(s) of horses; hence the last image is of two cuddly horses.
Ronny, Gregg, Charles, Basso; thank you so much for inspiring comments.
Basso, the last posted image was rather flat and dull light-wise so extra PP had to be used to add some life to it. Actually, I planned to shoot this building at night as it has interesting lighting.
hiepphotog – I don’t think colour casting with wide(er) angle RF lenses is specific to Sony A7 series cameras. If you search for images taken with Leica M9 or M240 without assign lens profile I believe colour casting will be the same. It’s either corrected in the camera or during the post.
I am still learning how to process colour cast removal, but lens profile in Adobe ARC and good lens profile for CornerFix are essential, IMO. If using CornerFix, refrain from correcting vignetting (Chroma = 0) and use vignetting reduction in ARC to minimize it and colour casting even for shots in f/8 – f/11 range.
Again, I absolutely agree that the extra PP steps are worth benefits of using smaller & lighter lens and sharp images across the frame, at least on modded cameras.

Jack, that's not what I meant. I got minor but noticeable color cast with the G 21 and ZM 15 on my stock A7s, but none so far on the modded cam. Those two are supposed to have much steeper ray angle, more vignette than the Elmar 24, yet the Elmar actually produces color cast instead. The A7s is the most resistant FF body out there to vignette and color cast. I have not done any Cornerfix or anything like that since I got one.
A pointer to a very technical yet insightful white paper from Zeiss entitled "About the irradiance and apertures of camera lenses", eight down in the list of such papers from the company, the section on exit pupils and focus methods (pp19 onwards) may interest some readers, and the paper has excellent diagrams and comparisons with the ARRI/ZEISS MP lenses (which were used on many of the Oscar winning movies this year):

Hi Hiep,
I still remember using test shots with my M9 for about 2 years with a number of WA's and it was very noticeable. I do think the best is Adobe FF correction if you are using Lr/CS. The results are excellent with no hint of magenta. Like Jack I do not use the vignetting correction with Adobe FF. Your 24 Elmar looks great and sharp corner to corner so after magenta correction the image will be perfect
My A7r M is great, but I still have an issue with having the correct minimum shutter speed. I do notice even with good technique and 1/125 sec there will some detail that is not sharp even with 50mm lens. I will raise the shutter speed and the detail is very sharp. Obviously this is a technique issue in part and a technical issue with the A7r shutter. This I am sure will be addressed with the A7rII ! For now I am comfortable working around this and the A7II is a dream to use at 1/10s in low light.
My understanding is Sony will not be announcing any news until the product is to be released in the market within 1 week if that. I have been told that since the Sony computers have been recently hacked, the information has been very closed shop and any pre news is unlikely.
