Hi
I posted on this yesterday but my post may have been confusing - it's a very complicated area for me (sorry I don't know how to paste the topic link in here).

I'm travelling by sailboat (sailed Australia via Sth & Nth Pacific Japan & Aleutian Islands to Alaska & soon will be heading back via more of Alaska, BC, Hawaii, etc.)

I've had stories published (with Nikon 1 pics) but only in Yacht Club magazines. I need better photos for some sailing & travel magazines interested in the voyage & the reason for it. So I now have a D7200 but no telephoto lens.

There will be amazing wildlife up in the Alaska section, but a sailboat also cannot often get close to wildlife & there can often be poor light.

So I figure I need a telephoto lens. But which?

I'm small (& not a teenager) & would struggle with a heavy lens, especially on a moving sailboat.

I'm not a wealthy "yachtie" so for instance I could not afford the new Nikon 200-500 even if I could get one.

Aperture is a factor given the poor light conditions. Steve Perry advises to get in close / use a TC / don't crop, etc; but using a TC cuts light further, so.......

Used (unless a hogger has something for sale) is not ideal as I'm leaving the US soon, so re-furb or new.

I've read many many posts & articles on the topic, but it would be nuts to spend thousands without knowing what I'm doing & why.

Does anyone have any thoughts on how they might go in similar circumstances?

Regards, Dione, Seward, AK.

Finally decided to buy a new D750 from B&H, ordered on Thursday evening, was shipped in two packages was supposed to be delivered Monday, it wasn't . Tracking says one package containing the spare battery was delivered, it WASN'T. (at least not to me) Tracking also says the other package was refused. It wasn't by me. Furthermore, tracking says it was refused in Pittsburgh, my address is NOT Pittsburgh
I called B&H and they say they can do nothing until it gets back to them, IF it gets back to them. I cannot find a number for FedEx
B&H also says they will refund my card when the camera gets back to them,but what about the package they say is delivered, I know of no way I can prove I did not receive it.
I also reviewed my order on B&H,s web site and the address IS correct

I have been around cameras for many years buying, using and selling them. I have tried every trick in the book to get the old ones clean but, somehow, they never really looked "clean and new".
The Mr. Clean Magic Eraser is the most incredible thing I have ever found. You just dampen it, give it a couple of swipes over the areas you want to clean and those areas literally become like new. Of course, care must be taken to not get any liquids where they don't belong. I follow up with a clean microfiber cloth. This product leaves no residue I can detect. Works especially well on camera grips and lens rings that have turned whitish. I have used it on camera bodies and lenses. I would be hesitant to use it on genuine leather, but it works so well on synthetic surfaces you won't believe it.

I am a former deer hunter and have a ground blind from which I see many deer, foxes, bobcat, and beautiful birds. I have been an event/portrait photographer since 2012. With hunting behind me I have developed a desire to shoot wildlife/birds (pardon the pun) with my new D750. While driving I notice birds in flight and beside ponds. I long to get a 200-500 but have a question. The reviews are mostly great and this is the best I could possibly afford. However, some owners complain it’s too heavy to handhold. I am 62 years old and in decent health. Need opinion from those who own (have owned) this lens. Please help. Don’t want to make expensive mistake.

I asked Canon why there was not a tripod collar included with their 70-200 f4, IS, II.

There answer was:
"We do have several versions of the EF 70-200mm lens as you may have noticed. The version you mentioned does not come with the Tripod Collar, while the EF 70-200mm f/2.8L IS II USM does come with it."

This is because the EF 70-200mm f/2.8L IS II USM is wider and weighs more than the EF 70-200mm f/4L. Its dimensions are 3.50 x 7.83" and it weighs 3.28 lb. In contrast, the EF 70-200mm f/4L comes in at 2.99 x 6.77" and weighs 1.55 lb.

"Our engineers concluded that a lens collar could offset the size and weight of the EF 70-200mm f/2.8L IS II USM but that it was not necessary for the EF 70-200mm f/4L."

I can easily answer your question with a simple response. There are two types of people in the world of photography, one group likes to talk about photography, while the other group wants to make photographs. I'm in the latter category, I make photographs.

F stops are quite simple, learn two neighboring f stops and you will have all f stops. Say f4 and f 5.6 as example. You then simply half or double either to reveal the other f stops. Of course one does not get anal about being 'precise' (double 5.6, that is 5.6+5.6 =11.2, round to f 11). I know, BUT! There is no BUT in the field of practical photography, or just steal that cute phrase, "Just Do It!" We are NOT doing math, we are making images.

Shutter speeds are the same but simpler (along with imaging speed/sensitivity), basic doubling (just like ISO, or the old ASA) 1/2, 1/4. 1/8, 1/15 (Don't be anal, no 1/16).

Yes, you can make it complicated, and loose the image, or make the image and put the camera away and study the math. In the latter I will just wonder away because I'm not here to do math, I'm here to make photographs, that is why people keep thinking that I'm a photographer, silly fools that they are!

Go ahead and ask Bubble about it (he is the guy in the photograph).
