  1. Note: Consider keeping uploads no larger than 1600 pixels on the long side when it matters, and sticking with 1000 pixels when the image feels no pain at that resolution. On data size/compression, try to keep things under 1mb, shooting for 600kb when you can stop there. Note that this includes photos hosted off-site (at Flickr, Photobucket, your own site, etc.). New to this thread? The general guidelines for these Wednesday threads are right here: https://www.photo.net/forums/topic/398109-guidelines-for-nikon-forum-wednesday-image-threads. For now, we're sticking with 1, 2, or 3 images per week as you see fit.
  2. That is a Galapagos hawk in Santiago Island (in Ecuador). I initially saw the hawk on a tree, and I posted an image to Monday in Nature: https://www.photo.net/forums/topic/551850-monday-in-nature-15-april-2024 It turns out that the hawk is banded on both legs, which would make it a questionable/inappropriate image for Monday in Nature. They use strong metal bands on hawks or they could have removed them with their beak. Initially I thought it was a tiny tracking device (which they occasionally use on birds) until I looked at that image enlarged.
  3. It turns out that this Galapagos hawk is banded on both legs, but that is obscured by the tree. Later on the hawk flew down to feed on a dead fish on the beach, and I captured some video where the bands are very much visible.

  5. 800mm PF @ 1/5000 sec. I was using 1/2000 sec initially but noticed a bit of motion blur, and I increased the shutter speed to 1/4000 and 1/5000. ISO was up to 1000 with plenty of sunlight.
  6. Canon's 28-70mm/f2 is a 3-pound lens. I wonder how much any 24-70mm/f2 will weight. I would much rather not carry that kind of weight for a mid zoom, because I tend to hold such lenses for a long time. Actually I use the 24-70/2.8 and 24-120/4 in low-light conditions. A lot of times I also need the depth of field so that I don't use the 24-70/2.8 wide open; instead I tend to stop down to f5.6 or so. It is the 70-200/2.8 and 400/4.5 that I use wide open to isolate the subjects.
  7. Unless Nikon deeply discount their old G1 version of the 28-75/2.8, and they have already been doing that to some degree, who in the right mind would buy the G1 optics instead of G2, when both are priced similarly?
  8. Nikon introduced the 24-70/2.8 S in early 2019, just months after they announced the Z System. I waited until November 2019 and there was a $300 discount on it. My local store had it in stock and also paid my sales tax. However, that is a lens I only use occasionally for indoor events. Concerning the 28-75/2.8, Nikon USA pretty much had to discount it immediately, after merely a month or two in early 2022. (Some early purchasers were really annoyed, of course.) I think they had a hard time selling it as Tamron already had the G2 available for Sony E. Now that Nikon allow Tamron to bring G2 to the Z mount, I think Nikon's own 28-75/2.8 is going to be discontinued or at least deeply discounted. Missing 24mm for this type of zoom is very annoying to me, though, regardless of G1 or G2.
  9. I have no idea what you did, but I replaced yours with just the link to YouTube. Hope this is what you want.
  10. Both Tamron's 28-75/2.8 and 70-180/2.8 have second generations (but not the 17-28/2.8), and those 2nd-gen version were available when Nikon introduced theirs using Tamron G1 optics. One would assume there must be some improvements in G2. In particular, the G2 70-180/2.8 has optical VR (VC in Tamron terminology). It is a bit strange that Nikon is still selling old optics. Perhaps Nikon will discontinue the 28-75/2.8 Nikkor soon.
