EOS Bodies - For Stills / Re: Wait for 5D4 or go for 5D3/6D right now ?
« on: January 12, 2015, 10:11:16 PM »

If you don't spend the extra portion of your budget on the 5d3 you can put it to good use on lenses.  Better lenses will make a bigger improvement in your photography than will better bodies. 

I don't agree with this common theory. It might have been true in the film days, but not with digital cameras. There are plenty of situations where better bodies will provide bigger improvements than lenses. Bodies can improve autofocus, low light and dynamic range. They can also improve resolution, depth of field control and flash capabilities. I think you would see a huge difference going from an XTi to a 5D3.
Of course lenses are important too, but bodies can also make a huge difference in some cases.

I would start with these two lenses. They will give you a huge range (24-480mm equivalent) with great image quality. I suggest buying them used if you want to save some money.
EF-S 15-85mm f/3.5-5.6 IS USM
EF 70-300mm f/4-5.6L IS USM

Any idea what this may be about?
This was on a two-page spread ad in the New York Times today in the front section.
The website has 45 hours left on a countdown timer...

This reminds me of a poor imitation of Apple's 1997 "Think different" campaign, when Steve Jobs returned.

“Here's to the crazy ones. The misfits. The rebels. The troublemakers. The round pegs in the square holes. The ones who see things differently. They're not fond of rules. And they have no respect for the status quo. You can quote them, disagree with them, glorify or vilify them. About the only thing you can't do is ignore them. Because they change things. They push the human race forward. And while some may see them as the crazy ones, we see genius. Because the people who are crazy enough to think they can change the world, are the ones who do.”


Image quality is, to me, not very subjective.  I'm only considering the results produced by the hardware used.
I'm not alone here with very high quality standards in that regard.
If you haven't run into such hardware limitations you're staying within your handicap.  If you're using various workarounds "that have been around for a century" then you're accepting a compromise or exercising an artistic choice to work within those limitations.
Some of us have artistic choices that require better hardware with less limitations to fulfill.  That's how progress happens.

Some people here react to this debate far too emotionally, with lots of passion and only a few facts.
The OP has not only shown examples, he's also provided his raw data and used a lot of his personal time and resources to do so, only to receive insult on top of (literal) injury.
Some of us have bolstered his findings with more examples.
Point is, these are facts, not opinions, about sensor system capabilities of Canon vs Sony.
It can be summarized as such:
- Canon is good enough
- Exmor is excellent
... in the one sensor metric where they differ substantially, low iso SNR and FPN.

+1 and bravo Aglet - beautifully summarized, objective post. Couldnt have said it better myself.

In the real world, the overall capability of a camera system includes various factors and compromises, not just DR (i.e. lenses, AF, frames per second, image stabilization, handling, build quality, skin tones,  etc...)   If you tabulate and score all these different factors, I think you will find that a 5DIII is a much more capable system than a A7r. Personally, I wouldn't trade the 5DIII's excellent AF system and lenses for a couple extra stops of DR.

EOS Bodies - For Stills / Re: Which Canon L Lens for 7D Mark II?
« on: September 30, 2014, 10:13:12 AM »
One of biggest problems with the 7D is that there are no good L zoom lenses for general purpose shooting. There is nothing equivalent to a 24-105L or 24-70L with high build quality and weather sealing.

Technically true.  There isn't an L-glass equivalent to a 24-105L or 24-70L for crop bodies.  But, the 17-55 f2.8 is essentially L-glass without the weather sealing.  True, the build quality of the 24-70 and the 24-105 feels better, but I wouldn't hesitate to recommend the 17-55 f2.8.  Put a good clear filter and you'll "seal" it from dust.

That is exactly my point. The 7D(I&II) is weather sealed, but Canon doesn't make a general purpose weather sealed lens to go with it. I live in a hot/humid part of the country. Every time I go outside in the summer, my lenses fog up. Since L lenses are weather sealed (with a clear filter), I can easily wipe them off. It would be a disaster if humidity got inside  the lens.

No question the 17-55 is a great lens. It just doesn't match the build quality of the 7D.

This is one of the main reasons I upgraded from a 7D/17-55 to a 5DIII/24-105L.

Despite the fact that the OP has already wisely purchased a 5D3, I will add one more point to this thread. One of biggest problems with the 7D is that there are no good L zoom lenses for general purpose shooting. There is nothing equivalent to a 24-105L or 24-70L with high build quality and weather sealing. It's ironic because the 7D is very well built and weather sealed. The only L option is to get a wide angle zoom like the 16-35L or 17-40L, but neither provides the range of a 24-105 on FF.

If you want to use L glass, full frame is the way to go.

By the way, I would recommend getting the 24-105L as your first lens. It's very versatile and pairs well with the 5D3. It's still my most used lens. The second lens I recomend is the 70-300L. Stunning IQ for telephoto and portraits. Very compact and well built.

Great choice on the 5D3. You won't regret it. You will notice a huge difference from the T2i. The AF, low light IQ and depth of field control are amazing. The handling and controls are also great.  Just a couple tips. Make sure to calibrate the micro focus for your lenses. It made a big difference for me, particularly for shallow depth of field shots. Also set up the joystick to select the focus point. This is the best way to take advantage of the 5DIIIs 61 focus points. This lets you just move the point instead of "focus and recompose". Much more accurate.

EOS Bodies / Re: 5diii to 7dii?
« on: September 23, 2014, 06:16:33 AM »
If you really want to downgrade you should get a 70d or an SL1. Both are great cameras and cost significantly less than the 5DIII. As others have said, going from a 5DIII to a 7DII doesn't make much sense from a technical or financial perspective, unless you are an action sports shooter.

Lenses are another issue. Your 24-70 just won't be nearly as useful on a 7D. You will probably need to get an EFS 15-85 or 17-55. Both are nice lenses, but expensive for non-L build quality.

If I were you, I'd just get a used Sl1 with a kit lens for casual shooting and keep the 5D3 for special occasions.

I for one am very happy about this. My old T2i with a 24mm pancake is going to be the perfect light travel kit. (It would be even better on an SL1!) Coupled with my 40mm pancake it will be a very versatile kit.

Sounds like a great trip, but I think you are crazy to take that much expensive and heavy gear. South America is great, but dangerous. I've been there many times and I won't even wear a watch or wedding ring, particularly in Brazil. You will get robbed! Some counties are safer than others, but you need to plan for the worst.

I would recommend the smallest possible camera. Maybe a cheap EOS M or Sl1 kit. It will make backpacking and travel safer and more pleasurable.
Last time I was in Brazil I took my old T2i with 18-55 kit lens along with my s100. It worked out well, but I was always very careful and vigilant.

Another option is to get a 40mm pancake. Great IQ, light, compact and cheap.

I think a 24mm pancake would be a perfect walk around lens for a rebel. An SL1 with a 24mm pancake would be a mirrorless killer.

Lenses / Re: Canon 70-300L IS + Kenko 1.4x Teleconverter
« on: December 01, 2012, 08:21:21 AM »
I have the 70-300L and a 5DIII. I purchased a Kenko PRO 300 AF DGX 1.4X on ebay and tried it for a few weeks. Overall, IQ was pretty good. It was definitely better than cropping. However, as others have mentioned, AF hunts quite a bit, particularly in low light.

I should mention that my unit was an older version. Apparently, the newer versions have a green or blue dot on them and have newer firmware that fixes some of the AF issues with certain lenses.

I ended up returning the Kenko and purchasing a used T2i body, which gives me 1.6x reach and better AF with the 70-300 (when compared to the Kenko+5DIII).

EOS Bodies - For Stills / Re: 450D vs 5D MKII AF system
« on: September 28, 2012, 07:50:57 AM »
I've got both a 450d and a 5DII. You will be very happy with the upgrade. The center point on the 5DII is very good and reasonably fast. AI Servo is also much better than the 450d. It also supports microfocus adjust, which is critical to get really sharp images with shallow depth of field. You will also notice a huge improvement in image quality and low light performance. The build quality, handling, LCD and viewfinder will also be a big step forward for you.

A bit of advise. Don't upgrade to a 7d. You will love the AF system and build quality, but you will be disappointed with the image quality and noise. The 5DII is a much more satisfying upgrade for a 450d user.
