Ok. I apologize. I will post my own question. Thank you.

If you can hand-hold a 600mm lens while following birds, more power to you. Rent or borrow one to see if you REALLY can.

Lens Authority has one for $620.00. I just purchased a G2 from them and it is pristine. They are the same people who operate Lens Rentals.

There ya go OP, Thanks to Rob909.
If you really think you need or just want a 600, here is deal for you.
If you diddle around on the fence and ponder, time gets buy.
Just buy the lens and if it does not work out you can sell it.

I had the G1 version of this lens a few years ago that I used on a 70D. I was not happy with it ... soft images.
I since bought a EF 100-400L IS version 2 and use it on my 90D ... and love it.

I happen to have my Tammy G2 on my older T2i, sitting on a tripod facing out my back window! I'm very happy with it, but suggest you do some practice before the trip. I did have to improve my sloppy technique using such a high powered lens.

Many people knock lenses when it's their technique that needs improvement...

BlueMorel, We own two of the Tamron 150-600mm (V1, one purchased used-mint and the other brand new during an Amazon sale after the first round of price cuts). We have them on both our DX and FX Nikons and love them. Whether it's right for you and your camera should be determined during a 30-trial, during when you should be able to do enough with the lens to say you love it or not; if not, and you've kept it in pristine condition, simply return it to where you bought it (ie, Amazon, Adorama, B&H, etc).

Eventually we'll get a G2 (or G3 or the sports model of the Sigma), but the $800 we paid for a brand new G1 was well-spent. Each unit has it's quirks and sometimes you may even find that though you love it, you need to send it in to Tamron to have it adjusted. That's what the 6 year warranty is for; use it:). It takes time to learn but there are many good photographers using it who have posted their methods and tips. Did that help talk you into it?:) Enjoy and happy shooting.

Here's the easy way and it avoids me talking you into anything. I'll send you enough money for a couple of six packs. Finish them in one evening and then sit down at the computer and make your decision.

Well, you've received all kinds of advice. The best is rent and try and the other buy a six-pack. It really boils down to this. Make a decision !!!! Join the rest of us that have spent one hell of a lot of money over the years and have learned one thing if we're LUCKY. Get what makes you comfortable for your pocket book and pictures you're interested in taking. If you don't you'll get NO WHERE. Be Happy. ZLZ7

Some reviews and some people slate these nonoem lenses, but we can't all afford the prime lenses, and then there is the argument for convertor, I have used a 500mm mirror lens, alone and with a convertor, I loved the size of the lens, and some of the great shots I achieved with it, the convertor made the pictures darker, and had a loss of detail, but could capture subjects from great distances.
But ultimately if I wanted to capture something closer I had to change lenses, so opted for a zoom lens, I have a couple of 70/300 lenses, one oem, and the other is tamron, the nikon lens has better lens quality, and I get cleaner images, but I found the response time of the af to be slightly faster, and more accurate on the tamron.
Last year I decided to upgrade, and had a play with a couple of lenses at my local camera exchange shop, I took my camera, and took a few shots of landmarks from same spot in store, I was shooting through the heavy plate glass windows, so I expected dsome distortion, but I was blown away by what I could do with the bigger lenses, I personally preferred the sigma purely because of af accuracy, and speed, I also felt more light got onto the sensor, so images had slightly more luminance, and a little more detail.
I left the store to have a good think, it's an expensive ad on, so had to make sure I had made the right choice.
After studying the images on my pc, I had made my choice, with online support, and updates, I chose the sigma.
I had a look online for new and used options, new was outside my budget, so started looking at second hand, I found a couple on ebay, and a few in second hand camera shops, I studied the photos of the products very carefully, at least 3 out of 10 that I looked at had issues, fungus, and mildew being the issues, I found one with great clear optics, no sign of any optical problems, I asked the seller to show me some of his results using this lens, he duly sent me a few pictures with data attached, so I could see the results at several focal lengths, absolutely stunning photos I might add, his hobby was bird photography.
So decision made I purchased the lens, thoroughly inspected it when it arrived, as described, in top condition, complete with jackets, and good carrying case, so my first trip out, managed to get some great shots, and over time have got used to it, have no problems carrying it, it's now my go to lens for most of my pictures only being swapped out for an 18mm lens when shooting landscape, absolutely best lens I have ever used or owned, I don't think you will regret getting the lens, and you may also find that the tamron is your go to lens, you also might prefer the images you get on that with Canon, the make of camera also effects what you see through the lens, and may have a bigger sensor than me, allowing more light through.
Good luck, and enjoy whatever lens you get.

We got my relatively non-shooter wife the Sig 150-600mm for an Africa trip. Shoots great and she got some stellar shots with that lens' range. I shoot Nikon only lenses so I eat that $ for the 200-500 mm, 180-400mm, …… That is such a great range tele that I am almost inclined to get one for my bag, but then I have to leave something else behind - or get a Sherpa.

Just in case you haven't yet been convinced here's three shots from the G2 on a Nikon D750, all hand-held, though I was leaning on a tree for the last shot, (I love the VR)
I know the G2 is $500 more, but from what I have read it is worth the difference if you can afford it (why I went with the newer version)
Best of luck with whatever you decide to do.
