Replacement 400d - 650d vs. 6d
« on: April 23, 2013, 11:45:49 AM »
Hi everyone,
been a lurker for some time, great forum, would love to get your advice.

I've been shooting with a 400d (Rebel XTi?) since 2007 and have been happy enough with the size, handling and IQ outdoors. I have an EF 28-135 IS and an EF 50 1.4 and a Speed Lite 580.
I feel like it's time for an update. The things I'm missing most are low-light capabilities (I try not to go over ISO 400 and only use ISO 800 when REALLY needed), so I'm often stuck with my 50 mm lens indoors. I love that little lens, but on a crop body I would just need something wider. Would also love a better auto-focus since currently 90 % of the pics I take are of my toddler, second one on the way.

Now there are two possibilities I thought of:
Get a 6d, that way my lenses would be more wide-angle, I'd have amazing low light possibilities and an improved auto focus. Might want to add a 100 mm Macro (non-L) since I'd like a Macro lens anyways and I could use it for portraits as well. Cons: Size (quite happy only shlepping a Rebel around), price. Not sure how much better the auto focus would do. Otoh would focus in low light.

The alternative would be 650d/700d or 100d. Pro: Somewhat improved light sensitivity, the question is just how much compared to what I currently have. Also smaller size compared to a 6d. Would have money left over to buy new lenses. As an extreme example 600€ for a 650d plus 2100€ for a 24-70 2.8 Lii is the same as a 1800€ 6d plus a 900€ 24-105 4L  :)

The other question would be whether it would make sense to still use my 28-135? I'm happy with the image quality but would it be the same on a FF sensor? (On the one hand bigger pixels, but on the other hand more vignetting?) The other question would be how much IQ I would give up on on a 6D. If not: What replacement to get? What "resolution" would that lense have? When I replace in a couple of years, would I have to buy new again?

Money is a factor, I would not be making any money with that equipment and in all likelihood won't in the future. The question is therefore more how much more light sensitivity, IQ and auto focus improvement I would get in a 6D, and whether it's worth the extra cash.

Thanks a lot

Sell your 400D and 28-135mm.  Buy 6D kit with 24-105L lens.  You've got the 50/1.4 for low light ambient and portraits, and the 580 to bounce off the celiing indoors as well.  Some improvement in AF, big improvement in high ISO performance, shallower DoF for portraits.
EOS 1D X, EOS M, and lots of lenses

@Neuroanatomist: Good idea, but since I wouldn't get all that much for the 400d (<150€) I might keep it; not bad to have a second body, especially since I try to get my wife into photography :)
I'm undecided whether I could afford the 24-105 at the same time as a new body, at least if it's a 6D. (I.e. I do have the money but there are plenty of other fun things in life that require my hard earned cash :) ) How much would I lose out on in terms of IQ if I were to postpone it? Mine doesn't have issues with barrel creep and the build quality is good enough for me.

The 5d ii is pretty much the same price here, unfortunately. Also, not having used either, the 6d seems to be considerably better for what I need (High-ISO), the Auto Focus migh and I personally find GPS and WiFi to be really neat features (still don't understand why Canon didn't put them in the 700D). Also: I'm used to a Rebel so I'd like the Body to be as small as reasonably archievable...
Forgot to add: Wouldn't want to buy used gear and I don't think they have Refurb stuff here.

The 1.6x crop of a 650D would actually be pretty useful for macro work, it's not the same thing as increasing the magnification technicall, but the desirable upshot is a greater working distance.  The 100mm will behave like a 150 focal length.  True tele macros are very expensive..  one arguement for staying cropped sensor.

I moved from a 400D to a 7D which was backed up with a 550D and now a 600D.  600D is cheap now, has fold out screen, wireless E-TTL flash (you can use your 580ex gun wirelessly off camera..very useful for your macro work!) which the 6D lacks (uses radio flash instead, you would need a new gun)

Higher ISO's are better, and there are more of them.  In practise, and with some LUMA NR at the raw conversion stage my 600D can deliver great results at 1600 and good results at 3200.  How much higher do you need?

I would ditch the 28-135 as it makes little sense on aps-c.  Go for a nice fast short zoom, something like the Tamron 18-50 f2.8.  Will really make the most of the AF.

You can get great results for modest cost, and a biggie for me would be the potential to model the 580 off camera.  This can make up for low ISO to some degree.

With whichever EOS camera you buy learn to use the AF system properly.  My advice is to select the centre AF point only.  Select AiServo mode.  Track, track, shoot a burst, track track shoot a burst.  You'll find your keeper rate goes way up.  Even more so the faster the lens you put on it.

If you get 6D, you won't use 400d. I know as I went through similar experience.

In terms of IQ, real IQ gains is at higher ISOs, and of course effect of shallower depth of field. I had 30D and I feel that ISO 800 on 30D was probably equal to ISO 12800 on 6D. Compared to 400D, I'm not sure, but it will be at least 4 times better. At least, maybe 8 times.

And as for focus, I take pictures of toddlers. When they get closer to 2 year old, they are truly hard to catch. So hard that I had 5D Mark III, and found it only a bit better than 6D. i.e. 6D autofocus is good enough. And quality of the picture is really spectacular.

I'd rather have 6D and 50 1.4, than any current crop sensor camera and bunch of L lenses...

Are you talking about using the Canon optical trigger system?   I don't know how reliable that's going to be at macro distances or out in the sun.  I think you'd be better off dropping $25 for some manual radio triggers or a cable if you need TTL.

I'm not doing that much Macro stuff (basically none so far). I just thought I would need a new portrait lens (current 50 1.4 = 85 mm or so on APS-C) and get the Macro as a bonus. Then again one never knows. My sister in law has a 600d; would probably go up to 1600 on that one, so I would gain 2 stops. Was there any improvement in the 650D (same sensor?).
As to the flash: Didn't know about the triggering, but I'd first have to learn how to use it off camera. I tend to avoid flash if I can, b/c when looking at the pictures afterwards I often have the feeling that the lighting of the scene (which might have been part of why I want to shoot something) gets destroyed somewhat. Might be based on technique, though. This is a hobby for me and I don't have anywhere near as much time as I'd like to have for it.
I want to be cautious about APS-C lenses, b/c there is always the chance that I want to move FF (just as I'm considering now :) ) and then I'm stuck with them.

@babiesphotos.ca: I thought more of giving the 400d to my wife ;) She's got small hands anyways... I like the 400D for its size, it feels much smaller and lighter than a 600d/650d/700d, especially with the 50 1.4. Would be even cooler with a 40 2.8 I guess. The 30D is basically the same size as a 6D, no?

Still unsure about the 28-135: On FF it would be a really nice focal length, my question is just whether the resolution is high enough for the new sensor. Any way to find out? I know that L glass would be much nicer, but to add another 900sth € should be well thought out (I'd also have to convince my wife).

As for 6D vs. 650D: The difference in ISO would be 2 -3 stops? Or even more?

Thanks guys

Hi Radiopath,

Last year I did a similar upgrade 400D to a 5DIII. The difference is much bigger than I had hoped, so i recommend it. I am biased to FF as I only saw crop sensors as a temporary measure until the sensor price could be made reasonable.

When I upgraded, I could only afford the body, so I went back to using my old 28-105 f3.5-4.5 from the film days. Your 28-135 is a bit better again. Overall it was a decent improvement on the old setup, but I have finally just purchased the 24-105L. Before that I grabbed the 17-40L which has been great and my first super-wide (it just made me realise that the old lens wasn't holding up too well anymore.

Anyway, I'd suggest that you consider the 6D, with some later lens purchases when the funds are available. Your 50mm will shine on a 6D (and a 85 or 100mm would be a great addition)

Swanny.

@swannd: I knew I wouldn't be the only one in that situation :) How much of a step up is that L lens really? Again, build quality doesn't matter THAT much.

BTW: I actually also considered buying a 17-40 a while back to use as a general lens as for now and having it as a UWA later :) Ended up buying the 50 mm and flash instead. Might also be an idea: 600 € 650D, 700€ 17-40 4.0 and a 50 € Ef 100 2.8 Macro. Wouldn't give me low light wide angle, though. Then again, more lenses to toy around with.

Added: Also, the 6D will drop in price, but then again everything does and during the time spent waiting I could take pictures. Especially since the silent mode sounds amazing to take pictures of new born babies.

The 30D is basically the same size as a 6D, no?

Yes, they're pretty much identical in size, weight, dimensions, feel in your hand. (I have both.)

Neuro's advise to buy a 6D with a 24-105mm kit lens is excellent.  Buying the 24-105 with the camera, you are getting it for roughly $200 off the price of buying both separately - a terrific deal.

If you don't want to spend that much now, the 6D will take awesome pictures with your 50 1.4 and your 28-135 will be good enough until you can afford to upgrade to a better quality zoom or expand your collection of primes.

I got a 6D after owning a T2i and later a 7D, which i still have.  My 7D is a great camera outdoors for fast moving subjects, but  the 6D opens up a whole new world of indoor and low-light options that were not possible on my APS-C cameras.  I take lots of indoor shots of our 12-month old son and the 6D / 50 1.4mm combination is fantastic!  Full frame image quality is a huge step up from APS-C in my opinion. 

Good luck with your decision.

Seems that most ppl here would favour a 6D. I read somewhere here that there will be Canon rebates around here in May, let's see, maybe there will be a possibility for a 24-105 as well, although there are always these little things on top that need updating when buying a new stuff (bag, SD-card, etc.).

Just one more question for the 24-105 4.0: With that aperture the DoF would be comparable to what on a crop sensor? 2.8?

Thanks a bunch for the advice, already looking forward to my new cam :)

For the same framing, f/4 on FF is like f/2.5 on APS-C.
