D2X with 500mm teleconverter 2.0 with HSC =1250mm OR photos with this combo would be helpful
Well, 500 * 2x = 1000mm, with HSC that would be 2000mm.
Not that I can really help without a D2x, but which 500mm did you have in mind? And which 2x TC? That would make rather a LARGE difference...
also multiply that by 1.5x = 3000mm
All this math gives me a headache.
My D2x/Sigma 500/F4.5 + modified Nikon 1.4 TC = 700 mm. 1.5 crop gives me 1050 mm, HSC mode gives me 1400 mm.
1.7 TC would have problems with auto-focus, 2.0 TC would be really soft.
sigma lens & converter
The HSC crops the sensor to half the size of the 35mm frame, so it really is 2000mm, not 3000.
thats three different answers but 2000mm sounds good
yes 2000mm is correct. HSC is the same as a 2.0 crop factor vrs film.
There are at least three different Sigma lenses that reach 500mm, in addition to the 300-800/f5.6 SigMonster.
Additionally, there are other Sigma 500's with apertures of f/7.2 and perhaps something else.
dont forget the 200-500 f2.8 :biggrin::Wink:
While I no longer have my Sigma 500 f4.5 HSM, what a value this lens is, I have used mine not only with the Nikon TC-20E but even with the TC-14 and the TC-20 stacked. Yes, with anything other than the 1.4TC's, and not Sigmas by the way, this lens will not AF, and especially when stacked. Here is one example, locked down tight on my Gimbal head, and take a look at the shutter speed.
500mm * 1.4 * 2.0 = 1400mm. I don't think it is too horrible.
Given that we are not far from each other, let me know if you would like to see this "Full Size", I'm sure we can make arrangements.
1/80 @ 500 mm
Even more bloody amazing, Bill said it totaled 1400 mm after stacking all that additional glass.
Correct, Ron, and thanks, it is pretty darned amazing. And I actually have real live witnesses to back me up :biggrin:
One strange thing, and probably why AF works with the Nikon TC's on this lens, is that the focal length and f-stop are not reported correctly in EXIF, as you can see they show up unmodified. I did have the benefit of a still day, I do a fair bit of pistol shooting so have decent breath control, and I certainly didn't take just one image, but a burst, which always helps.
Point being that while I hear the "can't get sharp photos with a TC" comments all the time, I have posted this image on numerous forums and have asked folks to show me where there is a major problem.
I would NOT by any means recommend this as a standard mode of operation. If the subject moves at all you are toast, unless you are far better at dealing with manual focus than I am. I have also had people tell me I must have an "exceptionally good" TC-20E, I don't know, I bought it used about 4 years or so ago from a friend of mine.
Now, if you want a combo that works great with the TC's, get yourself a Nikon 400 f2.8. I can auto-focus with the stacked 1.4+2.0 combination, that yields 1120mm f8. AF is a bit on the SLLLOOOOOWWWWWW side, and you need darned good light, it amazed the heck out of me when I tried it.
If you want a great long lens with or without a TC, look at the Sigma 300-800mm lens. Actually I have not yet tried it with a teleextender but it is very very sharp wide open. I am certainly happy with it.
