PowerShot / Re: Canon to Leave the Entry Level Point & Shoot Market?
« on: February 24, 2014, 04:33:36 PM »
Optical zoom will always outperform digital zoom, and there aren't yet many smartphones with optical zoom (and those that do look like the neighbor kid's toys on Toy Story), so smartphones haven't yet replaced, for example, the $90 Canon PowerShot A2200.

Lenses / Re: Best telephoto clarity for the money
« on: September 03, 2013, 06:45:40 PM »
If you can get a high enough shutter speed with the 400/5.6, that's sharper than the 300/4.  Both are very slightly sharper than the 100-400, but there is copy variation to consider, so you may find some 100-400s that best the 400/5.6.  The 70-300L is sharper than all three.

Wide open, yes. But at 300mm f/5.6 (the best both zooms can do at that focal length), the ISO 12233 test chart appears to show the prime being sharpest, followed by the 70-300L and then the 100-400.

Be cool if it was a straight f4...

Such a lens would cost at least $6,000. A straight f/5.6 would be much more affordable.

EOS Bodies / Re: A Big Megapixel Discussion

How much megapixels do you really need? Do you make printouts for big walls or big campaigns?

Or do you ever crop?

The A58 looks nice, too. 20MP and 8 fps for $600...

Lenses / Re: 70-200 f2.8II + 2xIII on 7D vs 300 f4 + 2xIII on 5D3

The next logical step beyond the 70-200 II + 2x or 300mm f/4 + 1.4x or 100-400, is the 300mm f/2.8 + 2x. But that's over $7k. Or you can wait for the 200-400.

EOS Bodies / Re: Camera (Body Only) or Camera with Bundle Kit

+1 on visiting http://strobist.blogspot.com, specifically read the "Lighting 101" article.

+1 on the 50mm f/1.8 and 85mm f/1.8. But I wouldn't bother with the EF-S 18-55mm lens. Instead, get the EF-S 15-85mm or the EF-S 18-135mm STM for better image quality (and video, if you get the T4i and the STM lens).

+1 on the Canon 430 EX II flash.

Lenses / Re: Selling 70-300 IS - Suggest Replacement?
« on: December 21, 2012, 08:21:38 PM »
If you want to go beyond 300mm, then sell not just the 70-300mm IS but also the 70-200mm f/4L IS, and get the 70-200mm f/2.8L IS II + 2x TC. Then you'll have the best of all worlds: 70-200mm at f/2.8, 98-280mm at f/4 (with your Tamron 1.4x TC), and 140-400mm at f/5.6 (with the 2x TC).

I'm not surprised. An updated version of this lens would cost around $1600-1700. If you're paying that much, you might spend the extra few hundred for image stabilization.

Lenses / Re: Which lenses will match a 40+MP camera?
« on: December 13, 2012, 04:31:00 PM »
...the center of the image is where you need the most resolution anyway, especially when you're using wider apertures.
It is okay for portrait, but not for landscape, city scape or interior of buildings.

Why would you be shooting those wide open?

All lenses have better resolution in the center area of the image.

Which is fine because the center of the image is where you need the most resolution anyway, especially when you're using wider apertures.

46MP on a 36x24mm sensor has close to the same pixel density as 18MP on an APS-C sensor. So you can test your lenses now. My 85mm f/1.8 stopped down just barely outresolves my 550D's 18MP in the center of the frame.

Lenses / Re: Canon EF 50 f/1.4 IS in 2013 [CR2]
« on: December 13, 2012, 12:23:38 AM »
A Canon EF 50mm f/1.8 IS USM, with ring USM, 9 aperture blades, sharpness exceeding the 24-70 II, and build quality equal to the 85mm f/1.8, would be awesome. The f/1.4 would suddenly become a niche item.

Just the 24-70 II, because it's at least as sharp as everything else you listed.

Am one who's still hoping for a replacement for the 100-400 L that's a bit sharper, better IS(a given) and lighter weight(I doubt it).

To avoid cannibalizing sales of the 200-400 lens, maybe they will announce a new 100-400 after sales of the 200-400 start to dwindle.
