Mary Doo Posted September 20, 2018 Share Posted September 20, 2018 In image 4, the reason for the lack of sharpness was that the focus point was not placed on the bee flying away as it still was pointing at a portion of the passion flower. Yes I saw that, I mistakenly typed in #3 as the image number. None of those bees were reasonably sharp, even @1/2000. However, the new set you shot with the D500 seems sharper, with the last image @1/200 and the first 3 @320. These are all moving objects, so a number of variables are involved toward creating the final image. I wonder if you would compare this lens with others on a stationery object - such as Shun's brick wall? Oh well, perhaps we should leave this task to Shun. :D Link to comment Share on other sites More sharing options...
Mary Doo Posted September 20, 2018 Share Posted September 20, 2018 Here are some cell phone pictures comparing the size of the Nikon 300mm f4 PF and the Nikon 500mm f55.6 PF Happy to see the much smaller size. :) Link to comment Share on other sites More sharing options...
mike_halliwell Posted September 20, 2018 Share Posted September 20, 2018 Jo, do you happen to have access to a 200-500mm ? I'm wondering if you can see what the effective focal length is at 500mm for close up stuff, like bees, ie how much the 200-500mm 'breathes', compared to your 500mm PF. It's looking very promising as a bug chaser...:-) How close are you to closest focus in the bee shots? I know it's a bit further than the 200-500m on paper, but magnification at that distance is unknown. Link to comment Share on other sites More sharing options...
joseph_smith3 Posted September 20, 2018 Share Posted September 20, 2018 Mike, for some of the shots I was as close as you could get or at the minimum focus distance. That statement applies to the image 3 and 4 taken with the D 500 and image 1 taken with the D 810. For those images the shooting distance was about 10 ft. For the others maybe another 2 ft or 12 feet. I am going to take some pictures with the lens on my D 500 and D 810 with am electronic extension tube to see how it works for macro work (and if AF is still functioning.) I do agree that this lens will have lots of uses for shooting butterflies, dragon flies, and other such critters. I also want to see if there is any vignetting when an electronic extension tube is used on a full frame camera. I doubt if there will be any such problems on a DX body like the D 500. To improve accurate focus, I am going to test other Dynamic settings on my D 500 like Group Area AF to see if that helps with bumble bee/close up shots. If you are going to use this lens on a tripod I suggest you consider getting a replacement collar and foot when they become available. The one that comes on the lens seems too "thin" and not robust enough to hold up well with frequent use. I am going to get a replacement lens cap to use instead of the plastic one supplied with the lens. I like the neoprene hood type lens caps.

ShunCheung Posted September 20, 2018 Author Share Posted September 20, 2018 Joe, speaking of the tripod collar, based on my discussion with Nikon, I thought it was like the one on the 70-200mm/f2.8 AF-S VR, i.e. only the foot part is removable. If the entire collar is removable, I would make sure it is secure, as some of you know my 200-500 fell out of its collar and is damaged. Link to comment Share on other sites More sharing options...
joseph_smith3 Posted September 20, 2018 Share Posted September 20, 2018 Shun, you are right about the collar not being able to be replaced. I had not noticed that. On the foot, there is a a push button so I could see how the foot could become unattached from the collar. I added a Wimberley lens plate (P-10, about 3.3 inch long) to my foot so the lens can fit Arca Swiss heads. The foot takes two screws. The foot is about 2.5 inches long.

mike_halliwell Posted September 20, 2018 Share Posted September 20, 2018 "The foot is about 2.5 inches long" Oh, the oddities of the Imperial measuring system!! You shouldn't get any vignetting with an extension tube, but I guess you might need quite a lot to get any meaningful effect. IIRC, it's a proportion thing, so a 50mm tube would be 10% of 500mm and get you, I'm guessing here (!) 10% closer?? Hopefully someone will correct this if it's wrong:confused: Link to comment Share on other sites More sharing options...

mike_halliwell Posted September 20, 2018 Share Posted September 20, 2018 I suspect indie manufactures will be making various feet to fit on the Nikon 'stub', so Arca Swiss, Manfrotto etc. Maybe even a blanking plate to take the sharp corners off?

Mary Doo Posted September 20, 2018 Share Posted September 20, 2018 It's looking very promising as a bug chaser...:) Guess it's OK if a cleaner background is not important under some situation. Normally a long macro lens yields a more pleasing background. But then one needs to deal with the depth of field issue. Link to comment Share on other sites More sharing options...
mike_halliwell Posted September 21, 2018 Share Posted September 21, 2018 Unless the dragonflies are more 'friendly' where you are, the chances of getting near one with anything shorter than 300mm is pretty unlikely here in the UK, unless it's early morning and they're cold.. The longest dedicated macro I know of is the Nikon 200mm f4. Maybe it's time Nikon refreshed it? With the 200-500mm I found it's 'happy spot' regarding DoF and sharpness to be around f9 and 420mm when at min focus. ------------------------ I've just had the 'instock' from Amazon UK at £3737, or Amazon Germany at 4146 Euros or $3600...:( With the £:$ at 1:1.25 it 'should be' £2900 and I dare say the Euro: $ should be equally better!

heimbrandt Posted September 21, 2018 Share Posted September 21, 2018 Regarding the tripod foot on the 500PF, I believe it uses the same foot as the 70-200E FL. Link to comment Share on other sites More sharing options...
ilkka_nissila Posted September 21, 2018 Share Posted September 21, 2018 (edited) I don't think we should assume that 70-200/2.8 replacement feet fit the 500 PF. Some 500 PF users report that their third party foot designed for Nikon 70-200 is loose fit and doesn't lock firmly whereas others report their 70-200 foot fits the lens ok. It seems likely that dimensions and tolerances are slightly different which can lead to this kind of a problem. I think it's best to either use a QR plate on the Nikon foot or wait for a new A-S compatible foot designed specificallt for the 500 PF from one of the companies who make such things.

The longest dedicated macro I know of is the Nikon 200mm f4. Maybe it's time Nikon refreshed it? Yes, it can be quite tricky as they are "scaredy cats". They usually hover around ponds, especially the damselfly - perhaps this aspect is similar in the UK? Fortunately it's a relatively large insect and the 200mm macro and some lenses can work well with it. Behaviorwise they usually come back to the same perch; so this makes it easy to plan a pleasing composition. The 500mm PF can do it but its 9.8' minimum focus distance would not make it my choice for this activity. Catching dragonfly is not my special passion; I shoot it when I happen to see it; however, I had the good fortunate to have caught it with both macro and long zoom lenses in the past. Here is one with the 200-400mm (minimum focus distance = 6.4').

Mary Doo Posted September 22, 2018 Share Posted September 22, 2018 Yup, 800mm + is about right for the nervy little critters.;) That's the advantage of using a DX camera + 1.4x. ;) In truth I did not intend to shoot dragonflies with this heavy telezoom. I happened to be looking for birds with with this lens mounted on the tripod and this dragonfly was at a good spot - see the blurred swaying vegetation at the back that made a pleasing backdrop. With the 500 5.6 lens at a minimum of 10 ft's focus distance, the image would include undesirable distractions. You would need the 1.4x to bring the insect closer and make a better background.

joseph_smith3 Posted September 29, 2018 Share Posted September 29, 2018 I almost had a disaster with my 500mm f5.6. I picked it up by the lens foot and the lens fell off! Fortunately it fell on my bed and not the floor and was not damaged. My finger must have touched that button on the foot that holds it on the lens. Hopefully a replacement foot will solve this problem from happening again. Are there any tips on how to prevent the foot from disengaging besides not touching that button ?

ilkka_nissila Posted September 29, 2018 Share Posted September 29, 2018 If the foot is like that of the 70-200/2.8, there are two locks, if you tighten the screw knob, it should't come off by merely pressing the lever that is the secondary lock.

heimbrandt Posted September 29, 2018 Share Posted September 29, 2018 Yes, Illka is right, tighten the screw knob on the foot and verify that the lens will not slide off if you press the lever. I doubt a replacement foot will use another locking mechanism. Link to comment Share on other sites More sharing options...

Are there any tips on how to prevent the foot from disengaging besides not touching that button ? Many years ago, when I was holding my 70-200mm by an RRS replacement foot, it fell off to the ground. Fortunately it was a board walk, the metal hood was hit and no fatal damage was done - though the filter thread became very tight since. How to prevent it? I never held it just by its foot any more. The replacement foot designs have most likely improved now. Edited September 29, 2018 by Mary Doo Link to comment Share on other sites More sharing options...

The replacement foot designs have most likely improved now. As a lot of you know, I was holding my 200-500 by its tripod collar foot, and the entire lens barrel fell out off the collar, hitting the floor at home from about 3 feet, resulting in a $285 repair bill. After almost a month of parts hold, that lens is finally on its way back to me. In time for me to make an A/B comparison between the 200-500 and 500mmf/5.6 PF, whenever Nikon sends me a test sample. 1 Link to comment Share on other sites More sharing options...
joseph_smith3 Posted September 29, 2018 Share Posted September 29, 2018 Thanks for the tip to keep that knob tight. I thought it was but I guess it was not tight enough. Link to comment Share on other sites More sharing options...
Mary Doo Posted September 29, 2018 Share Posted September 29, 2018 Thanks for the tip to keep that knob tight. I thought it was but I guess it was not tight enough. Perhaps also double-checking the tightness every now and then, as the screw can come loose over time. Enjoy your lens! :) Link to comment Share on other sites More sharing options...
Andrew Garrard Posted September 30, 2018 Share Posted September 30, 2018 Perhaps also double-checking the tightness every now and then, as the screw can come loose over time. I do check mine whenever I'm taking the lens out. But then I've always worried that I have screw loose anyway. Link to comment Share on other sites More sharing options...
ilkka_nissila Posted September 30, 2018 Share Posted September 30, 2018 I check the knob when I mount the lens on tripod (in my case don't yet have the 500 PF but the 70-200/2.8). I don't carry the lens from the foot rather I hold the barrel and camera in my hands (and usually camera strap around neck) when walking and shooting. 1 Link to comment Share on other sites More sharing options...
