Trying to upgrade please help

I currently own a 40D and a 60D, I am thinking about purchasing a 6D but am I correct that all my Canon EFS lenses won't work on the 6D? I also have two Tamron lenses SP-AF-DI 200-500 and a 28-300 aspherical XR DI, would those work on a 6D? I want to upgrade but don't want to have to replace six lenses. Suggestions please.

Canon EF-S lenses will not be compatible with the 6D EF mount. Not sure about your Tamron lenses.

The Tamron lenses have a red dot. So that is the key, a red dot works with the full frame camera the white dot doesn't?

If a 3rd party lens was made to work with EF-S, it will mount, but you will still have an EF-S lens, ie: the image circle from the lens will be too small for your larger FF sensor.

So basically I would have to buy all new lenses if I bought the 6D? Is there any other camera that is an upgrade from what I have that has wi-fi that I could use with my current lenses?

Without googling, 90% sure that both tamrons are FF lenses.

Tamron designates FF lenses as: Di.
Lenses designed for APSC are: Di II.

Di II lenses will mount and function on full frame cameras. You will get a round image surrounded by blackness with them on FF bodies. My 17-50 Di II worked just fine on my 5Dc. However, the results really sucked.

If you want wifi on a crop body, I believe the 70D is your choice.

Is the full frame body that much better than what I currently own for me to buy a new camera and lenses?

It depends on what you're shooting.

But your question does suggest that, at this time, full-frame might not make a big enough difference to you to warrant changing everything up.

In typical situations, there's not an enormous difference between them.

The biggest differences will be found in -

Low light/High ISO performance is significantly better on FF bodies.
Per pixel detail is better if the megapixel count is similar - a 20MP FF image vs a 20MP crop camera image with similar quality lenses will show an advantage to the FF image.

Larger sensor size necessitates longer focal lengths to acheive the same viewing angle. AKA you have less reach with a telephoto lens, and you have less depth of field on the FF camera. To make things roughly equivalent, multiply the aperture on the crop camera by the crop factor for what it would look similar to.

For example:

135mm f/2 on crop

135 x 1.6 = 216mm
2 * 1.6 = f/3.2

So a 135mm f/2 lens will give similar results to a 216mm f/3.2 lens on a FF camera.

500mm f/6.3 on crop ~= 800mm f/10 on full frame

500 x 1.6 = 800
6.3 * 1.6 = 10

The full frame camera will need to use a higher ISO to acheive the same shutter speed - and this also factors in to equivalency. The FF body will need to use a higher ISO, but it will result in fairly similar image quality.


If you're looking at faster glass, here's one in reverse:

50mm f/1.2 on full frame

50 * (1/1.6) = 31mm
1.2 * (1/1.6) = f/0.75

So a 50mm 1.2 on a FF camera would be like a 31mm f/0.75 on a crop camera.

FF is less important if:

Crop cameras offer enough image quality for what you're doing
You're limited by focal length. If you're limited by focal length you will need a much larger lens to get similar results from the full frame camera
You need a faster camera: right now there's no inexpensive Canon FF body with great AF/frame rate performance

FF may be a good choice if:
You're not focal length limited by what you're doing
You desire the ability to print larger or use higher ISOs
You desire the ability to control depth of field even more

I mainly shoot landscape and nature photography. I wouldn't mind spending the money on a new camera and lenses if the end results justified it.

Heya,

Eh, unless you're doing huge prints and unless you need an extra stop of low ISO shadow push, you're not going to get a huge difference in landscape from a 6D compared to a 60D with good glass. Most of it is in the technique and processing. If you look at a lot of the stunning landscape work in the best of' galleries, you'll note a lot of APS-C's in there that you'd never expect.

I'd get the 6D if you wanted the ISO performance at the high side of things.

I'd prize a good piece of glass and filters over a camera, personally.

Can you post some of your work that you think would be significantly improved had you shot it with a full frame?

Very best,

Here are some samples of what I usually shoot.
