  1. Niels, I understand that the lens becomes a 6.3 with the TC. But my original understanding was as Ed described - "The diaphragm opening is the same, with or without a teleconverter." Which I take as meaning that the diaphragm continues to open at 4.5.
  2. Thanks! What brought be to bring up the subject in the first place was how a teleconverter would affect this process. For example, my newly purchased z400mm is 4.5. With the 1.4x it becomes a maximum 6.3. Does the it still acquire focus at 4.5 or at 6.3 when using the TC?
  3. I once an read an article explaining how a camera will always focus at the largest aperture of the lens that is attached to the camera, regardless of the f stop that is selected. . For example a 400 2.8 lens will focus at 2.8, even if a smaller aperture is selected. It went on to explain it is why a lens with a large aperture will always focus faster and more accurately than a lens with a slower, smaller aperture. I was trying to to explain this concept on another forum but wasn’t real successful in making my case. Does anyone have further information or maybe a different explanation? Thanks!
  4. Posted the above back in March when I received my z9. As Joseph suggested, I posted my concern and suggestion for a focus memory / focus distance recall control function on Brad Hill’s blog. I was ecstatic to find out today that firmware version 2.0 for the z9 gives that exact function, and more! Focus distance recall can now be set to virtually any fn button on the camera or on a z lens within buttons. In fact, multiple focus distance recall points can be set to different fn buttons! Have no idea whether it was the result of It being on Brads blog or if Nikon already had it in the works, just very glad they did!
  5. So, last week I took possession of the Nikon z9. After playing around with it for a few days, I have come to the realization that what I thought was a focusing issue with my z7 and z7II may in fact be, in fact, an overall weakness of mirrorless cameras. For example. I am shooting small birds with the new Nikon 100-400mm z lens at about 30 to 40 feet. All of a sudden a a hawk flies overhead at approximately a hundred feet. I lift the camera into the air but, because the camera is focused at 30’, it’s impossible to locate the hawk. To make matters worse, the 100-400 has an electronic information panel that indicates focal distance, aperture, exposure compensation, etc.. that is activated with the push of a button. So, there is no way to tell what distance one is focused at without activating the display. This isn’t a problem with my 500PF as it has a focus recall button which I have programmed to focus at infinity with the push of a fn button on the lens. As soon as I would see a subject at a further distance than what i was shooting I could immediately recall the focus at infinity. This was never a problem with the d500 and d850 since they don’t have electronic viewfinders. I would be interested to hear from those of you that have had similar issues and if you have found a workaround.
  6. Just received my z9 a few days ago and I am trying to determine if it has the ability to recall a focal distance. I am finding that when I need to quickly shoot at infinity, such as in a BIF situation, often I am unable to locate the subject quickly enough to focus before the subject is out of range. Maybe there is another way to accomplish this? My 500pf lens has the focus recall feature which I find myself using very often in these types of situations. Your help is appreciated!
  7. Recently, I came across an article from a popular online photographer and I’d like to hear other’s opinion of his statements. For whatever reason, after thinking I had nothing left to learn this pretty much amazes me. If true, how would this apply to a telephoto zoom lens with variable aperture. For example, a 100-400 4.5-5.6. Will the focus occur at 4.5, regardless of the focal length, since the aperture decreases to 5.6 at 400mm? Your thoughts are appreciated! “An f/2.8 lens like a 400mm f/2.8 is always going to focus faster and more accurately than a f/4 or f/5.6 or f/6.3 lens EVEN WHEN THE APERTURE SETTING IS THE SAME. What this means is if I am shooting with a 400 f/2.8 lens that is set to f/5.6, it is going to focus faster and produce sharper images than if I was using another lens such as a 500mm f/5.6 lens that is set at f/5.6. This part is important: Our cameras do not step down the aperture to the f/stop we have set until the moment the shutter button is actuated. This means that anytime you are walking around, looking through your viewfinder, or acquiring focus, your lens is actually set to its maximum aperture.”
  8. Thanks Shun, I just checked the 100-400. It looks fine.
  9. Update - After receiving and using the 1.4 TC on my 100-400mm Z lens for a couple of weeks, I returned it today. As I mentioned in my previous post, I was looking forward to how it would compare to my 500PF. I was initially disappointed in its sharpness at 400mm (560mm). I originally felt as if I just need to get used to it a bit more since I had only had the 100-400 for a short period of time. But I decided to return it when I discovered that it might actually be defective. The rubberband type of material that protects the lens housing. (see Shun's first picture above in which he compares the 1.4x F mount to the z mount) was torn in places which resulted in it not fitting tightly around the housing. I don't think this in itself was causing the softness. However, when I began to remove the TC from the 100-400 lens, I noticed that the piece of rubber was actually slightly sticking up over the top of the housing, I was able to re-fit it to the housing and reinstall to the lens. However, when I removed the TC, the rubber protector was again coming off the housing. I felt like it might possibly be interfering with the glass. So, I have returned and am waiting on a replacement. Hopefully, this is an isolated incident. I will update once I receive its replacement.
  10. Ordered the 1.4x today for my 100-400 Z. Looking forward to seeing how it compares to the 500PF. The 100-400mm by itself is a real treat so far. Incredibly sharp and significantly faster focus compared to the 500PF on my z7ii. Miss not having a focus recall button.
  11. I should know this since I once owned the 80-400 but, I wonder what focal length changes the new 100-400 to f5.6. Or, I guess asked in another way, what focal lengths will enjoy f4.5?
  12. Thanks. I had read in different forums of CFx readers being incompatible with cards other than those by the same manufacturer. Good to know that its working ok with Lexar and ProGrade cards.
  13. Shun, any idea if it is compatible with San Disk CFexpress cards?
  14. Thanks Ilkka. I have asked the question in a few different forums. To be honest, after the photo is imported into Lightroom mobile, I don’t find it to really be a problem as I have no need to export as a original (nef) file. Since Lightroom mobile allows me to edit the nef and export as a jpeg, that’s all I really need. The issue is really with Snapbridge. I suspect that it hasn’t yet been updated to be compatible with the apples iOS. Or, apples iOS hasn’t yet been updated to be compatible with the z7II’s nef files.
  15. As I mentioned above, the same issue occurs when importing straight to Lightroom mobile to the iPad or phone. And yes, I have tried using a card reader.
