  1. Actually, 50APO and 28 Summicron II.
  2. Oh, I see where you are going with this... maybe the cow doesn't like the leather bag? No worries, it is a Thorsten von Overgaard Crocodile Bag. Cow got nothing to worry about. 😆
  3. Just kidding of course... I do like your chic shots, especially when you have them take their clothes off. 😆
  4. Very nice, but try a higher shutter speed to compensate for motion blur. 😆
  5. I get this a lot when I'm shooting Leica... there is always that one that comes up to me and asks, is that a Leica?
  6. Hello Jono, Nice photos... the best part of your reviews, for me. Matty the dog looks so proud and happy!
  7. What is your distance Rx both eyes?
  8. Yes, but the image you see is still virtual It does that too and that is mostly what creates the effect that the frame lines are floating in the VF. The mega perl thingie (I have one don't use it) is on the outside. Leica is probably saying they would have to incorporate it into the optic of the eyepiece and that would necessitate a complete redesign to incorporate the plus lens in the eyepiece Japp, have you tried to figure out the puzzle I asked Jeff to perform to determine if the FLP rays exiting the eyepiece are -0.50d?
  9. Jeff, I still think the -0.50d in the viewfinder was done by Leica to compensate for what is known as instrument myopia. That is where a viewer looks into an instrument and sees an image and assumes it is a near image and therefor the eye tries to focus(make plus). With the Leica RF, instrument myopia would be even worse because the eye sees a virtual image that appears to be a near image so the eye focuses and becomes more myopic. This makes the distance image in the VF world blurry... so Leica added some minus(-0.50) to compensate for all of that. The old eye can't focus and starts to notice that the image in the VF is blurry and hard to focus... so you get a diopter to do it for you. BUT, THE -0.50D IN THE VF IS NOT WHAT CREATES THE APPEARANCE THE FRAME LINES ARE FLOATING AT 2M. THAT IS CREATED BEFORE THE REFLECTION ON THE PRISM MIRROR.
  10. I think he is sort of correct. As Ive said the -0.50d is for the viewfinder. The reason you don't see much difference in the FLP is because there is no -0.50d in that image for you to neutralize with your diopter lens. The reason you notice a difference in the VF is that you are neutralizing the the -0.50d
  11. Ha! You can do a little optical sleuthing with that lens. Add it to you eye piece and see if the VF image is clearer... you've done that Now black tape over the front of the VF and try the same with the FLP and see if it neutralizes the -0.50d that is supposedly there? Or, can you detect a slight blurry. I'd be curious to know.
  12. Yes Jeff, your sunglasses have UV protection.
  13. When I chose edit and change my post it creates a whole new post that I have to delete r just change to more comments. But, let's not post now about this and derail this thread.
  14. Not to drag the comments off track from 01af's post... The -0.50d from the VF causes the eye to focus. Specifically, the eye must produce plus power in the lens inside the eye at an amount of +0.50d in order to see clearly. The eye flexes the lens and this plus lens become thicker. A younger eye can do this but not an older eye because the lens has become crystallized and is not able to focus. Eventually, this process of the lens getting more rigid(caused by a Shiff base reaction cross linking the glutathione pairs) goes on to produce a cloudy lens and eventually this become what is known as cataract. Live long enough and get cataract. Death, taxes and cataract. 😆
