On an earlier post I had some questions about using DxOMark ratings to help select a camera and lens(es) that would let get me print gallery quality 16x20 landscape prints. Of course, I want to do other things, too. Thanks for all the great discussion around this.

After lots of research I'm thinking it's between the Nikon D750 or the Canon EOS 80D. Both have 24MP, environmental sealing, WiFi, lots of AF points, articulated screen. The 80D is lighter and much less expensive. I could add the Tamron 70-200 F2.8 to either and an 18-35 for wide angle (possibly the Sigma on the Canon, very highly rated for $800). No doubt the D750 is more camera, but not sure it's enough to justify the big price difference. And, Canon has the 80D refurb with one year warranty. I like the savings (D750 plus two really good lenses is a stretch), and I also like the convenience of the smaller lighter APS format. Maybe upgrade, or just add a full frame later.

But, I am reading about problems with the Tamron 70-200 and the 80D. Will not autofocus. Camera freezes in live view. Doesn't seem to be a problem with other Canon APS cameras. Does anyone know if this is a real problem? Has it been fixed?

Any other comments?

Thanks again!

Well I have read tons of literature and I have to say I've not seen anything about the problems you're talking about. I recently ordered and just received a refurbed 80D from Canon.

I too had the same concerns when I purchased a 80d refurb body from Canon directly. I went to the Tamron website and also talk to Tamron but my existing 18 - 270 lens. I was gratified to find out that my lens was not being affected by this failure to autofocus in live view. There are certain Tamron lenses that are affected and the best suggestion I have for you is to contact him run to find which lenses were affected.

When I get contact Tamron by phone they indicated that they were developing firmware to fix this problem of autofocus in live you with their lenses. You can delve further into this issue when you talk to them .again good luck

If it is a problem it must be selective or intermittent; I have used my Tamron SP 70-200 model a009 lens on my 80D several times and have not had any problems with it. I don't know if it's just a problem with live view; was going to run a test but remembered I lent my 6D with the Tamron 70-200 to one of my daughters and won't have it back until next week.

Jack, welcome back!
If I were in your shoes I would not opt for the 750. Not because there's anything negative about the camera, I just wouldn't spent the extra $1000 or what ever it is. Use the money to get some more lenses or a tripod or flash or all of them. You'll be miles ahead setting yourself up using the saved money on the extra gear.
As to the AF problem, I know nothing about it. I will say that there is always a potential for a problem while using a 3rd party lens. Certainly there can be more potential for issues in the future with new bodies that come out.
Good luck in whatever direction you go!

The d750 is a superior full frame camera while the 80D is a smaller APS-C crop sensor camera. Don't assume any equality because they are both 24mp sensors. There is a lot more to it than that. The D750 will almost certainly give you better landscapes than the 80D. The field of view with your preferred 70-200 lens will be completely different depending on which camera you mount it on. The Sigma 18-35 is a crop lens. While you could use it on the D750, you would not be taking advantage of the full sensor or the entire 24mp.

As in your previous thread, I still think you're still focusing too much thought on numbers, and the two cameras you're comparing are like apples and oranges. You need to do more research on the specific differences and capabilities of your choices. If you want true gallery quality, of the two cameras there is really only one choice, the D750.

I'm not a Nikon fanboy. In fact I'm a Canon shooter and my preferred camera for sports/wildlife is the crop sensor, professional level, Canon 7D Mark II, but I would not have purchased it for landscapes.

I recently purchased an 80D refurb from Canon. And my two primary lenses are Tamron. Getting them to focus was a hair pulling trial. I have it worked out finally.

Read the manual, again and again. There are multiples of multiples focusing settings on the 80D. They all have to work together to get the Tamron's to work.

Now that I am through that I can start learning the rest of the camera. So far the quality, sharpness of my pictures has increased since the upgrade.

Just my 2 cents worth.

Thanks,

I think I understand the difference between crop sensor and FF. Maybe I've got this wrong, but it is my understanding that that with APS you do use all the pixels, but you don't use all the light with a lens designed for full frame because some of the light is focused beyond the dimensions of the smaller sensor. And, smaller pixels capture less light. So, you need a slower shutter speed or higher ISO. Should not be a problem when there is a lot of light. I do like sunsets and sunrises and that may be an issue, but may still be solved with a tripod.

I get the point about the numbers so I looked at a lot of images. No doubt the D750 images are sharper (as the numbers would predict). I also found that sharpness varied more with the glass than with the camera (which is also what the numbers would suggest). With landscapes, I also found that the most beautiful images were not always the sharpest. Ideally, I would have want a full frame 5D series at more than 30MP, but that busts the budget and the D750 stretches it quite a bit.

I did a little more digging on the Tamron lens issue and it looks like a firmware issue that has been solved. I also found a refurb Canon EF 70-200 F2.8L at the same prices at the Tamron, so I may just duck the issue. I know, 70-200 is not your typical landscape lens, but I don't only do landscapes.

I should also say I lean toward Canon since my son has Canon and we can share lenses, and from what I read Canon is generally better in terms of innovation, quality, and service (do you agree?), though Nikon seems to give you a bit more for your money in terms of features and IQ (according to the numbers).

Will want to make a decision soon.

Thanks!

Sticking with the Canon lens is a good idea if dollars will let you. The 80D manual has several pages of Canon lens listed and how to set the focus settings to work best. I would love to have all Canon but don't want a second mortgage to finance their purchase.

I ended up with single point focus and it works, even with the 60mm macro.

For wide angle the Canon 10-22 is top of the line quality at $600 - their newer 10-18 is lighter, about half the price, but according to those here who use it, outstanding in quality.

This is a post I did two years ago after I got the 10-22mm lens, showing what it can do. It is a great lens!

The quick and easy way to work with this problem is for you to rent the bodies you think you may want, along with a 50mm lens of the brand you're looking at, and go out and shoot 100 photos. See how you like the actual photos, and how the camera fits your shooting style, and ergonomics. If you son own a lot of Canon lenses, and Canon body, borrow his camera and a lens. As far as comparing the 80D to a Nikon full frame, I don't know but it is not a fair comparison.

I still can't for the life of me figure out why everyone seems to think there is something mystical and magical about a 50mm lens.

I personally don't find that focal length very appealing on a 35mm camera, and barely find it acceptable on a cropped sensored camera.

Clearly you don't shoot in very low light or want a very thin DoF. The 35mm and 50mm are exceedingly useful for indoor close work in low light.
