Lenses / Re: 24-70/4 MFT charts

I must admit 0.7x magnification at minimum focusing distance of 7.87 does seem awfully handy, especially since a small macro extension tube (with electrical contacts preferably) will easily make it a true Macro lens.

No, actually - it won't. Add a 12mm tube, and the max mag goes down. Add a 25mm tube and it goes up to a 0.72x (at the wide end, it's 0.4x at the long end with the 25mm tube).

Huh, can you point me to the calculator or formula you are using?

I'm getting 0.94x magnification with 20mm extension tube added to the 70mm telephoto end using the stated minimum focus distance of 20 cm.  I'm using this calculator:

Sigma actually just released the price of the 35 F1.4 DG HSM for $899.

$50 higher than Canon f/2 IS with one stop more aperture but no IS. 
Since there's always that dreaded worry with Sigma lenses having AF "issues" with Canon, it's somewhat comforting to see that new Sigmas come with USB docks:

"Sigma developed proprietary software (SIGMA Optimization Pro) and a USB docking system that allows you to update the lens' firmware and adjust its parameters such as focus without having to ship it back to Sigma for adjustments."

Maybe because you are getting 2 lenses in 1! You get a standard zoom + a Macro HIS! The price is just MSRP. It'll drop in price a little, then get hit with a rebate, and all of a sudden peeps will feel the urge...

Well, the price will drop eventually, but it will likely take years before it drops to levels the 24-105 dropped to considering MSRP is still listed as $1149 on Canon site. 

I must admit 0.7x magnification at minimum focusing distance of 7.87 does seem awfully handy, especially since a small macro extension tube (with electrical contacts preferably) will easily make it a true Macro lens.. Hope the Canon can match the sheer incredible sharpness of Sigma 70mm macro lens.

If one goes by the MTF chart at Canon site, the 24-70 f/4L should be pretty sharp, especially compared to 24-105.


I just got my 100L macro lens and realise I need macro extension tubes and macro rails. I shot some six legged creature that was about 1.5mm long! This is the first macro lens I have owned.

I use both the 100L and 65 MP-E, and honestly, while macro focusing rail (and macro ring flash) is an absolute MUST with MP-E with its up-to-5X(!) magnification and no IS, 100L with its hybrid IS is much more forgiving for hand-holding.  Unless you plan on going the MP-E route, a Macro ring flash (doesn't have to be expensive Canon) may be a better, and more fun, investment IME. 

Even dedicated macro shooters sometimes find it a drag having to lug around a tripod and macro focusing rail on a "fun" macro shooting..

Hope that is from the last few years with less "issues."

Kasey BD with their speedlite mount is a solid choice.

If cheaper is needed, the 22" ebay BD is fine, although with less-than-ideal bracket.

I personally use the Speedotron BD with Kasey adapter/bracket for Alien Bee strobe, not speedlite.  One could buy the Kasey speedlite bracket and use it on Speedotron BD as well.

I really like Imagenomic Noiseware, which I use as photoshop plugin.  It gives you many different ways to reduce noise, and I find the NR cleaner without killing off too much detail.

« on: October 31, 2012, 07:33:10 PM »
I'm really hoping for EF 55m f/1.3 (why not 1.2?).  Call it L and charge $2000 if you want.  As long as it's a bit sharper with a bit faster AF, I would buy it.

While I certainly don't regret upgrading to the 24-70 f2.8 II as it a super lens, AND I do hope Canon releases an IS version, I will be just a little piqued that after spend the extra increase for the non-IS version, that I will have to consider what to do on the IS one.   If both had been released simultaneously, would have just spent the extra for the IS.

Judging by the recent price drops of 5D III, it seems Canon strategy is to launch with as high a price as possible, then drop the price some months later.  If 24-70 IS is launched, I suspect it will sport a price similar to $2300 the 24-70 non-IS sports currently, but the non-IS then likely will drop in price around that time to say $2000.

The new Sony NEX-6 with EVF and the new 16-50 mm lens.

EOS Bodies - For Stills / Re: 5D3 focus for birds in flight
« on: October 28, 2012, 03:01:00 PM »
As improved Al servo is on 5D III, I still find one shot AF to be much more reliable.  Since things like birds mostly don't change pose, unlike sports capture, I have better luck with one shot mode, in Tv mode with high shutter speed.

Honestly, I'm pleased with the Sigma's price. My guess is that it will be a better performer than the 35mm L which is $500-600 more.

That would be a HUGE presumption IMO. 

Lenses / Re: 85 1.2 L2 not sharp at 1.2
« on: October 23, 2012, 07:04:31 PM »
Does anyone have problem getting sharp image at 1.2? i even tried manual focus and AFMA. i only get sharp image at 2.0 and up. should i return for different copy?. i bought it recently just to use at 1.2 since i heard so many review on how sharp it is at 1.2 to 2.0. Any thought?


Before you return it, do some testing on tripod in good light to see if the lens is the problem.  It would be even better if remote shutter release is used.
