Aperture determines more than shutter speed.  Most people don't buy an 85mm f/1.2L to use it in very low light (which turns out to be a good thing, because unknown to most people, when you shoot at f/1.2 on a dSLR your camera is actually bumping up the ISO to compensate for the fact that the sensor is less sensitive to light at very high incident angles, and not telling you...meaning over 1/2 a stop more noise in some cases).

Hmmm interesting. I never knew the camera did that. Now, when you say that the camera bumps up the ISO without telling you, does it only apply in settings where the camera meters for exposure, or does it do it for manual exposures as well? In other words, if I choose an ISO of 200 manually, would the camera actually shoot with ISO ~300?

Thanks for the response guys. For now, I think the best option for me would be the 500D filter. If I find myself doing more macro work in the future, I'll probably go for the 100mm L.

United States / Macro Lens vs Close up filters vs Extension tubes
« on: January 22, 2012, 04:19:59 PM »
I'm not really a macro shooter, but I like to have something in my arsenal so when necessary, I can shoot macro. Not sure if I want to drop over $400 for a true macro lens when its not going to be used very often. That being said, what are the major differences and trade-offs between Macro lenses, close up filters and extension tubes? I am leaning toward the Canon close up filter, but not sure if its the best substitute. I've heard it does not do 1:1 magnification. While I understand the magnification concept, how much of a real life difference does it make? Thanks in advance.

It is a big chunk of cash for a glass. But it really does perform. I think dollies and sliders are way too overpriced, but thats just me. Just think of it this way. You can get years of good great photos with this lens and then if you want, you can sell it without much loss. These lenses hold their value quite well.

Its definitely mark I. The mark II's focus ring is slightly wider.

@gadun: Love those macro shots. Great job!

Lenses / Re: 50mm f/1.2L and 85 f/1.8 VS. 50 f/1.4 and 85 1.2L

I have to say that IQ wise, there's little difference between the 50 1.2L and 50 1.4. The bokeh is slightly better but the build quality is significantly better on the L. Thats one of the reason I only buy L lenses.

Being a shutter-count paranoid that I am, I would have difficulty putting that much mileage on the body for 1 project. Nonetheless, truly nice work!

Lenses / Re: 135L or 100L macro?
« on: January 11, 2012, 04:52:09 PM »
Just wondering: would I get a better IQ and bokeh by using the Canon 135mm 2.0L with the 5d Mark II, or the 85mm 1.2L II with 60D? I already own the 2 bodies and the 85, do I really need the 135mm?

I've actually done this test, 5DII + 135L vs. 7D + 85L II (same sensor as 60D). For IQ, the 5DII+135L wins (sharper corners, less noise, much less CA, but more vignetting).  For bokeh, the quality is about the same (and the quantity of OOF blur is the same for 85/1.2 on crop as 136/1.9 on FF, so effectively the same).

OTOH, the 85mm f/1.2 gives you something the 135L cannot - f/1.2 on a FF camera. DoF doesn't get much thinner than that, and the 5DII + 85L is a great combo!

Thanks. This helps a lot. I might get the 135mm later this year. Thanks to kubelik also for your input.

Lenses / Re: Good deal on the 35mm 1.4?
« on: January 11, 2012, 04:03:02 PM »
Not a bad deal, but you could've saved a bit more if you had ordered it from Abes of maine with $15 coupon (code: Loyalty15), the price comes out to $1,244.95 with free shipping. Add in to that another 2% cash back (which you get after ~3 months) if you sign up and go thru and you final price for that lens: $1220

I'm going to be ordering that lens later today so if anyone here has a better deal, please do share :)

Only issues with "Stacking" filters is it can cause vignetting. 

I also heard the the B+W CPL MRC can introduce a bit of this as well and have been debating going to the slim for my CPL instead to negate this

Actually, that depends on the lens being used.  Some time back, I tested several lenses for the effect of stacking filters on vignetting.  Surprisingly, many lenses can tolerate a pretty thick stack of filters.  For example, the 35L at f/1.4 shows no mechanical vignetting even with 3 F-Pro filters stacked on it. On the other hand, the 16-35L II will vignette with an XS-Pro plus F-Pro, meaning a standard CPL will vignette, as will an XS-Pro with a slim CPL stacked, but the slim CPL alone will not.

Here are the lenses that I tested, and the results:

Thanks for the comparison results. I recently ordered a B+W xs-pro UV filter for my Canon 16-35mm f/2.8 II lens, but was a little concerned about whether or not it would cause any vignetting. Glad to learn that it wont :).

Lenses / Re: Thinking about either getting the 35mm 1.4L or 50mm 1.2L
« on: December 29, 2011, 04:48:44 PM »
I had the same dilemma and went for the 50mm 1.2L a month ago for the exact same reasons. Since your future setup consist of both the 50mm 1.2L and the 35mm 1.4L, its a logical choice to get the 50mm now and wait for the 35mm 1.4L II. I will wait till Jan 3rd to see if the new 35mm is announced. If its not, I'm getting the current one next week.

Just bought a New Canon 16-35mm 2.8L II for $1100.00  ;D

Just won the auction on eBay the other day for a Brand New Canon 85mm 1.2L II for $1500. I've been hunting for a deal on this lens for a while. Can't wait to get it!
