17-40mm for 6d?

Hi, I'm new here
I'm upgrading my canon 550D to a 6D
I mainly shoot portraits or group of people that are indoor and the iso performance with the 550D is really bad. So after reading a lot i found that the 6D is a great low light camera.
The kit lens am getting is the 24-105mm.

I also like to shoot landscapes so I'm thinking of getting the 17-40mm for it but dunno if i'll need it since i have the 24-105.
Also, I currently have the 50mm 1.8 for portrait but heard it doesn't work as good with a FF body, so i'm thinking of getting the 85mm 1.8.

I can't buy both at the same time so help me decide what I should get first and I'm open to new lenses if there are any.

Hello, welcome to POTN.

I have both the 24-105 and the 17-40. I use the 24-105 when I want to just carry 1 lens around without having to worry about changing or when I don't know what I'll be shooting specifically. When I know I'm going out to shoot landscapes, I take the 17-40 along with the 70-200 because they cover my preferred landscape focal lengths perfectly.

Whichever you get first depends on what you want. Personally I'd go for the 17-40 first because I love UWA.

Since you currently use your 50mm f/1.8 for portraits, I would first add the 85mm f/1.8 to replace that functionality on the 6D. You can then take your time to decide if the wide end of the 24-105L is wide enough for your landscape shooting.

While I do own a 17-40L, I find that 24mm is wide enough for the vast majority of my landscape shooting. An UWA is a nice tool to have, but you need to know when to use one.. and when not to.

Use the 24-105 for landscapes first and if you feel like you need a wider lens, buy the 17-40.

50mm not being or being good for portraits is a matter of preference. I you like FOV of the 50 on your 550d for portraits then you may find it too wide on the 6d, but that is up to you to determine. There are some really good deals on 85s in the for sale section so that might make the 85 worth picking up regardless

You will most likely find the 24-105 on the 6d wide enough for most of your uses although the 17-40 will give you a relatively inexpensive way to get wide.

Wow!! Thanks a lot guys

I think i made up my mine. I'll be getting the 85mm first since i could use the 24-105 for landscape shots and most of my shots are portraits.

Since you have the 24-105, you could use it for most of your wider shooting. If later you decide you want something ultra wide to add to that, I would recco considering a fixed wide, like a 15mm or similar.
You will like the 85 1.8 on the FF. It will work well both in the studio and for outdoor location shooting. Outdoors, used correctly, it can produce photos with very nice BG blur.

And yes, welcome to the forum. Do some searches thru the forum for threads that have photos taken with the lenses you are considering. You will find plenty of inspiration there.

I read somewhere that the 17-40 does exceptionally well on the 6d.
I guess from a technical standpoint, why does the sensor/optics combination improve on this sensor/combo over a crop or older full frame?
or maybe it's just an exageration

For little more than the price of the 17-40, you could get the 85/1.8 for portraits and a Canon 20/2.8 for wider shots. Those two primce and the 24-105 would be a good starting setup.

You should be able to use your 550D to ISO 3200 without too much problem, and 6400 with a bit of extra noise reduction (see Teamspeed's posts about high ISO 7D shooting... it's the same sensor and processing as in the 550D).

6D will be about a stop better shooting RAW, maybe 2 or 3 stops shooting in-camera JPEGs.

I have bought all three lens's over the last three months and moved from 550d to 6d. Indoors the IS on the 24-105mm means I use it more than any other lens. You should get the 24-105mm.

I did post a noise test video on YouTube a couple weeks ago called full frame vs crop sensor (noise test) in which I compared pictures taken with both 550d & 6d

Thanks again everyone

I will consider buying a wide prime lens but i still prefer the flexibility with the zoom wide lenses in order to pick the best composition.

@DigitalTechLife
would you please post the link for the video? and does the 17-40mm go along with the 24-105?

at work so I can't look for link now. Between the 24-40mm range I prefer the 24-105mm due to the IS. in the short term for landscapes you can always do a panoramic and stitch with Photoshop or other software. I bought 6d body first then the 24-105mm followed by the 17-40mm and lastly the 85mm.
