I have an older Canon PIXMA PRO-7000 Printer (two models before the PRO-100). I have some similar issues. My new PC has Windows 10 but Canon is not supplying Win 10 Drivers for their older printer so I have it working pretty well with Windows 7 - 8.1 Drivers. But I get no custom profiles and like you there are some weirdness to the sizes of paper. The printer only seems to list Canon Brand Sized Papers, and I have many brands of paper, Canon, HP, Kodak, Staples, etc. I had to "trick" the printer into printing the size image I wanted. As I recall I was printing to 13x19" paper but wanted a 13x17" print. Kinda the reverse of your situation. Perhaps you have to print via Ps, Lr, or some other photo editor for that "professional" size. I think I had to play with the margins and put in some odd negative values for the position of the printed area used on the paper.

Let me play with Ps and the Printing App a little and get back to you if I figure something out.

If you want to keep the weight and cost more reasonable, you could go with the Canon EF 70-300 IS II USM for $550. I've been using one on my 80D for about a year and am happy with it. It gives respectable reach and IQ and isn't very heavy. I have taken a few thousand racing photos at Laguna Seca and Sears Point, as well as other photos with mine. One of the reasons I resisted getting a DSLR was seeing the big zoom lens that my good friend (a Nikon shooter) carried around at the track, but then I realized I didn't need the huge lens (I was using a Canon "superzoom"). The aforementioned combination works great for me. Apparently the Canon tele-extenders don't work on it, but that isn't an issue for me.

The Sigma 150-600mm C is actually pretty light and portable for a lens that reaches 600mm. At about 4.3 lb. it's roughly half the weight of a typical 600mm f/4 prime, for example. And it's 95mm filter diameter is a lot smaller than the 150mm front element typical of that same prime.

However, if you're willing to give up some "telephoto reach" with a lens that "only" goes to 400mm, you can shave off some weight.

The best of all of them is the Canon EF 100-400mm L IS USM "II"... It uses fluorite to be extremely sharp throughout it's focal length range. At about 3.5 lb. it's roughly 3/4 lb. lighter than the Siggy 150-600 C, as well as a lot more compact (77mm diameter filters). It costs about $2000, which includes tripod mounting ring.

Both Sigma and Tamron are also now making 100-400mm lenses, too. And each of them offer those lenses for about $800. And they both weigh around 2.5 lb., roughly 1 lb. less than the Canon 100-400mm or 1.75 lb. less than your 150-600mm.


HOWEVER, throughout their range of focal lengths the Siggy and Tammy 100-400s are 2/3 to a full stop slower than the Canon lens... they don't offer as large aperture, so are going to be more limited in low light conditions. They also don't use fluorite, so have more chromatic aberration and a little less sharpness than the Canon. And, neither the Tamron nor the Siggy come with a tripod mounting ring (something I consider mandatory for a lens of this type). It's a $129 option to fit one on the Tamron. There is no option to add one to the Sigma 100-400. Of course, adding the tripod mounting ring to the Tamron lens will increase it's weight a bit... Not sure exactly how much but I'd guess it would be around 1/2 lb., bringing that lens to around 3 lb. total.

Your 80D can autofocus the Canon 100-400mm with a 1.4X teleconverter installed, making it a 140-560mm combo (with f/8 at the smallest). The Canon 1.4X III teleconverter (about $450) is said to work quite well with the lens, too... tho personally I haven't tried it. I also have no experience with and don't know about using other brand teleconverters on the Canon, or using the other 100-400mm lenses with various teleconverters. But it's a possibility you might want to consider... A 1.4X TC would you the option to have almost the same "reach" as your 150-600mm at times, if needed, but the removable teleconverter allows the lens to be smaller and lighter when you don't need it.

Yes, there's also the new Tamron 18-400mm "crop only" lens that can be used on your 80D. It's a pretty amazing lens.... the first and only lens to cover such a range. HOWEVER, look carefully at reviews and compare. That lens is all about convenience (never having to change lenses) and it has nowhere near as good image quality as any of the above less extreme options (and especially the Canon 100-400mm II). I also am not sure how it's "PZD" focus drive mechanism performance compares with the ultrasonic drive used in all the above.

Finally... you mention "keeping junk out of your camera" by never changing lenses. That's just plain silly. First of all, lenses don't prevent stuff from getting inside the camera. Zooms, in particular, "breathe" a lot of air in and out during normal operation... and some of it may contains dust particles that find their way inside the camera. Second, common sense precautions during lens changes are all that's really needed to keep cameras reasonably clean and minimize dust issues: try to make changes in sheltered, dust-free areas; do the lens change promptly, leaving the camera open to the air as little time as possible; and point the camera downward while doing the lens change to reduce risk of dust settling inside. Particularly with cameras like your 80D which have a very effective self-cleaning sensor, these simple precautions make sensor cleanings far less frequently necessary... but I can assure you that a cleaning will still be necessary from time to time, even if you never remove the lens.

I shoot a lot of competitive equestrian events... which can be extremely dusty!

Back before cameras had self-cleaning sensors, I sometimes had to do manual cleanings monthly... at a minimum did them 3 or 4 times a year. Now with self-cleaning sensors, manual cleanings are needed far less often. Rarely more than once a year. I do use multiple cameras and may try to walk away to a less dusty area to change lenses, but I still make lens changes (quickly and carefully) when needed. Even in conditions like those shown above!

I have both the 7D II and the 80D and I use my 80D far more often than the 7D II. If the 10 fps is the main reason for you to get the 7D II, forget about it. You will do just fine with 7 fps. The 7D II is a nice camera but it's getting a bit long on the tooth. For the money, seriously consider a factory refurbished 80D. Good as new, same warranty as new, quite a bit less expensive.
I've bought 2 factory refurbs and 1 brand new 80D and there was absolutely no difference between them.
You could also wait for the 7D III to come out.

A couple of years ago, my husband and I went to the same area where you will be. The reason was for me to photograph the bears, and my husband’s was to see if he could entice one of the bears to eat me so he could collect my life insurance. Just kidding about the second part of that previous sentence.

My serious response is that I took my Lowepro Photo Hatchback 22L (no longer made, but you can find new ones on Ebay). It has a self-contained waterproof cover that is truly waterproof. It rains a lot where you are going, so waterproof is important. When we went, I carried a Nikon D7200, Nikon D5200, Tamron 150-600, Nikkor 55-300, and a couple of other lenses. Biggest mistake I made while photographing the bears was that I did not have a lens attached to each camera. Just had the 150-600 on the D5200 and left the D7200 and 55-300 (NOT attached to the camera) in the backpack. When at Brook Falls, I missed shots because the 150 end of the 150-600 was too long. It was raining and I wasn’t able to get the D7200 out and put the lens on it. Didn’t make that same mistake on Kodiak.

Something to keep in mind is that you can actually wear a backpack on the front of your body. This would allow you to access the contents without taking it off. If you wanted to go that route, check the arrangement out at home to determine whether or not you can shoot with that configuration.

Have fun! Send photos!
