I have the Canon XSi (450D), which has and APS-C sized sensor. I have been told on more than one occasion that image quality and performance between a FF body and a crop body is phenominal. I've been trying to find some good articles that outline specifics of why FF is better than crop, and so far I have not been able to come up with a whole lot.

It appears to me that the larger sensor allows for a larger pixel density, resulting in higher sensitivity, and clearer images. The FF bodies seem to have better processors, resulting in better processing of colors, and faster performance.

I have two questions. The first being, do you have any advice on the matter, and/or links to good articles in this area? The second would be do you think I would get better images with a 1Ds MK II, vs my current XSi (450D), and be pleased with the change?

I want to try my hand at shooting weddings in the near future, and am beginning to get my gear together. I realize that if I go to FF, none of my lenses will work, without vignetting. I am considering selling my XSi, kit lens, and Sigma 10-20mm EX DC, and start over with FF. I have only read great things about the MK II, and it seems like an awesome camera. I can get a used body for $1,800 at Adorama, in slightly used condition.

FF and never go back imo. Never got a 1 series because spending 8 grand on a new camera was a stretch even for my impulsive self, but look into used 5D's too you might find some deals.

Bleh.
Oh and here's a discussion about the topic:

I would definitely opt for the 7D over a FF body, but that's coming from someone who has never actually owned a FF body. Right now the 7D seems like the best of both worlds.

^^my thoughts exactly.

although, if i had money, it'd go towards lenses first, body second.

One world is FF and the 7D is not FF so how is it the best of both worlds exactly?

Because it has good high iso performance and still retains all the best aspects of crop bodies?

Sorry but full frame wont make you a better Photog and if you have the lenses to fill the 1.6 like a 10 or 11mm then it is like having a 17mm on a full frame. Granted the 5d2 has better high ISO but its not going to be a game changing thing..It all depends on the person. I can careless on FF because I gear more towards speed and action stuff. So a 7D and a 1D 1.3x Camera are the only ones I personally would ever buy. Others might not want that. In the end its not really going to make you take better pics.
The AF is pretty close to the same on the XSi and the 5D/5D2..Also the frame rate is pretty much the same to. So these things wont make you get any more shots if you were taking faster shooting type. Thats the one Major flaw of the 5D2..Canon for some retarded reason used the SAME focus system in the new 5D as the old 5D...Why i have no idea. If they would have gave it the 7D AF system it would have really made it a much more powerful all around camera.

Can anyone say from experience how the 7D's high ISO performance is? Unless I shoot with the intent to use high grain in the composition of my photos, I can't shoot over 400 with my current body without a lot of color noise. I hate color noise.


Thanks, Lala. I found this link within that discussion:

It does a side-by-side comparison of a 1.6x crop vs FF. Interesting results.


I hadn't even thought about the 7D. I'll have to look into that one. I have heard lots of great things about the 7D. At least then I won't have to get rid of my Sigma 10-20. I love that lens.


I'm thinking I might do this. I really want to get a decent telephoto.


Interesting points you make, there.

Because serious sports shooters chase the 1 series.

5D was always the tool of the wedding photographer.

the High ISO of the 7D is VERY good..Id say its pretty close to what my Mark III is


HMMMM actually ALOT do..and maybe you should read more as well..cause I said it depends on what you use it for. Like i said in start of this..ALOT of them do go for a 1D for weddings as well.

Point out where you say either one of those things.

if you read through it..You will see "It all depends on the person" I guess you dont like to read

And your the one who said people dont use the 1D for weddings. I never said anything about that in my first post.

Either way, weddings are all about using a flash, so you probably wouldn't really need to go above a 40D/50D to be properly equipped for a long time if that's your goal.

Interesting point, Jason. I just did some comparison of the 40D, 50D, and 7D. Aside from the Video, and slightly higher resolution, the only notable difference between the 50D and 7D that I saw was the AF system.

Does anyone have experience with both the 7D and 50D? Do you think that the 50D would perform satisfactorily in a wedding environment, using the 580 EX II?

I already have one 580 EXII, and if I get another APS-C body, I'll probably just keep my XSi, and get another 580 EXII later for it. The price difference from the 7D and 50D seems to be decent.

the 7D high ISO from all the photo comparisons I have seen are much better then the 50D. The better AF would be a big advantage. Any camera would really work..I mean if you are a seasoned wedding photographer..you could do it with a XTi...remember the 7D has the commander mode..You can remotely fire the flashes off body

Seeing that the XSi has the same AF system as the 50D (on paper), and I'm pleased with the performance so far, I doubt I would be missing out in the AF area.

Now, as for the cammander mode, I did not know about that.

no the 50D has a much better AF system then the XSi..the 50D all the points are cross type with 5.6 or faster lenses..the center is cross and diagonal sensitive with 2.8 and faster..the XSi only has center point cross type with 2.8 the rest are not

Feel free to quote where I said that.

Keep trying...

Thanks for the clarification, 05X. There is so much to Photography that I still don't know. I'm just glad that I'm a person who always wants to learn. It's a good thing that I'm in no hurry to get this wedding photography going. I'm just trying to grow my hobby into an income source.

don't worry too much about gear. a good photog can make a good picture with whatever they have. focus more on the craft of making pictures as well as defining how and what you want to shoot.

Before you upgrade all your gear based on the off chance you can make money at weddings, find a local pro and second shoot with them a couple of times. You'll make a little money and find out if you even like what wedding photography is all about.

I wouldn't go FF just for weddings personally. It's all about the photographer, having a FF camera won't make you a better one nor will it make or break any wedding shots IME. One of the locals here still shoots with her 20D and an XT as a backup and takes wonderful wedding images. All in what you know and not what you carry.
