t4i to 70d..how much of an improvement?

I think the only reasons to go with the 70D would be to increase keeper rate: Ergonomics and controls are significantly better faster frame rate, better AF solutions, and even weather resistance are all going to help you get the shot.

Keeper-to-keeper, the T4i is fine though.

you have the 24-70 f/2.8L II in your gear list
I would say go for the 6D instead of the 70D
but if you like the crop , the 70D is great in low light with fast primes like what you have the 50mm f/1.4
but be sure to test the camera focus in the store using a fast lens at f/2.8 from 20 feet distance

"but be sure to test the camera focus in the store using a fast lens at f/2.8 from 20 feet distance"

moltengold - Could you elaborate a little on this please? Particularly what to look for. I assume this is to check for the well discussed focus problem.

Timely thread, I also have a T4i and have been wondering about and fondling the 70D. I have pretty much realized that the upgrade benefits would very minimal for me with the possible exception of auto-focus. I need to learn lots before I need to spend more on a body.

Thanks

70d IIRC takes advantage of dual pixel technology for video. Micro adjust is also in the 70d.

A must have IMO

sure Rick
here you can read all the info about some copy's
https://photography-on-the.net …/showthread.php​?t=1354075

I bought two 70Ds but I didn't notice any problem with all my lenses
just the cheapest one 50mm f/1.8 sometimes miss the focus at 1.8 to 2.8
i sold the two bodies because I don't want to send them to the canon service

Thanks, I have read a lot of that but not all of it.

I was really asking about how you do the test you mentioned, but maybe that is also in the same thread?

Thanks again
Rick

Exactly, it's not hard at all. You use the histogram. If you are not using the histogram to gauge how far left you are going so you can pull up the image later, you are undoubtedly underexposing by a stop or even 2. This could mean that your ISO 800 is really an ISO 3200 shot, but the noise, in my experience, will look a bit worse than actually running ISO 3200 and exposing properly.

This is great advice and is exactly what I have started finding. It has taken a while to get used to myself as I would use the histogram to get things as far to the right as I could then bottle it when I saw the JPG previews on the camera screen, everything looking totally over exposed. Last airshow I did I shot manual, set exposure using the histogram and made a serious effort to ignore the preview image and once all the images exposures are pulled back the noise is much better than just exposing normally. Any while I don't post much on here I do read a lot and if you are going to listen to anyone on noise reduction advice it does seem like TeamSpeed is the man

I can't wait to try this on some camping trips so I can get some camp fire photos without pushing the ISO way beyond what the rebel is really capable of.

moltengold, I have just been looking at that thread again and there is lots of testing information there and other places.

That camera kind of scares me. Especially being less experienced than most of you guys.

Thanks

no need to be scare
i always change my gear , I can't stay with one camera for three months
I love to see , try and test the others bodies
i buy and sell with a loss , it's like renting at the end
now I'm using the smaller one the 700D its a great camera too for the weight and the price
and I hope this camera stay with me for a long time

Yeah, nothing is an absolute. As the camera sets exposure for 18% grey, bright elements in the scene will drive dark elements to be even darker. ETTR help capture the darker aspects, and simple adjustments to a RAW image in post can recover some of the blown highlights, if any. The worst situation is to boost the exposure in post - major increase in noise results.

I frequently shoot +2/3 stop, but not always. If the detail we're after is in the highlights, we would probably swing the exposure the other way.

My default start +2/3 EC on my 60D and +1/3 EC on my 6D. And I almost always use Evaluative metering because I am most familiar with how it behaves.

Ya, I have the T4i or 650D as it's called in some places, pretty much the same as the 700D I believe.

It is a vary nice camera and much lighter than the 70D. Weight is an issue since I travel overseas for work and every little bit of extra weight adds up. I'm going to think this over a while longer. Could very well be just GAS, know what I mean? Maybe the Christmas or after Christmas sale prices will convince me, we'll see.

Rick

yes the T4i ( 650D ) same as the T5i ( 700D )
I will wait too
good luck , Rick

I have become a bit frustrated withe the t4i s low light inabilities.. seems anything over 800 is not really usable and even 800 is not that great..So I am looking for an improvement in that area..how much of an improvement would the 70d be?

I mostly use the camera for family events and street photography but I have been getting into portraits latley..it's during those family events that the iso becomes an issue..

I will go full frame eventually bit I'd like a good crop body as well..is this canons best performing crop body? (In terms of high iso)

Something's not right here. I get incredibly clean images at 800 ISO with my 700D (which effectively is a T4i/650D), my 50D and even my 20D.

Post a few examples of what you're talking about.

As a point of reference, you should be getting something better than the image posted below ,, 20D at 800 ISO.

In my opinion you have three options:
1) Low cost: learn to ETTR and post process in Lightroom
2) medium cost: get a 50mm 1.4 lens for low light
3) Higher cost: trade the t4i for a 6D.

I don't think a 70d would be worth it, if noise is your main concern.

You forgot to mention that the most benefit is derived from the least expensive option.
