Third Party Manufacturers / Re: Extenders - Kenko vs Canon 1.4's & 2.0's
« on: February 23, 2013, 10:59:57 AM »
I now use the Canon 2x III on a Canon 70-200 f2.8 IS II, and I am very pleased with the match.
The Canon 2x III doesn't show the ugly OOF-artifacts I observed on the 1.4x II.
Cheers

I am glad that combination has worked for you. I'll share a different experience.

I tried the 7D / 70-200 f2.8 IS II / 2X III combination. Intitial shots showed severe Front Focus Issues. I talked to the folks at CPS about the setup asking if Microadjustment settings would remember the combination as its own lens, or would it also apply those microadjustments to the 70-200 by its self also. They could not answer that question, so I exchanged that extender for another. I later discovered that the combination is remembered as it's own lens.

Based on the intial bad results with the replacement extender (and really wanting that combination to work for me) I tackled lens Microadjustment. What I discovered was that at 400mm, the setup was fairly accurate, (although also somewhat inconsistant) with little or no adjustement needed, but at 200mm I needed to adjust focusing to +12 on the -20 to +20 scale. I decided this was not going to work for me, so I returned the second extender.

I understand that lenses and extenders are built to tolerance ranges, and if the tolerances of the lens and extender are at the oposite ends of that range, problems could result. CPS suggested I borrow one of their 2x's to compare, as the ones I purchased may have be built together with similar tolernces towards one end of the scale. I have not tried that yet. I may give the 1.4x a shot but I really wanted to get to 400mm.

HDR - High Dynamic Range / Re: Best HDR Software?
« on: January 14, 2013, 10:02:22 AM »
Just wondering which HDR Software you like to use the most? For me its Photomatix 4!

If you're interested in HDR, Canon's DPP software that comes with their cameras now includes an HDR feature. They added this feature 8 to 10 months ago, so you may need to update the software from Canon's website. The benefit to the HDR feature in DPP is it's free.  They also added a compositing feature too for blending images.

I've dabbled with DPP, Photomatix, and Nik HDR, and I don't have a clear favorite at this point.

Lenses / Re: Canon 100mm macro IS vs non-IS - any further input?
« on: January 11, 2013, 12:54:06 PM »
My usage would be weddings plus typical insect and floral macro shots.

If you are using these lenses on a tripod for macro, in my experience you will need a tripod collar. The overhung weight will create some vibration and noticeable blur. The Canon branded collars are in the $175 to $200 range and should be factored into the purchase decision. Just my two cents.

I've got the 7D, but to me it was so far off I didn't think the micro-adjustment would work. I also called CPS and the guy wasn't sure if the microdjustment would remember the lens/extender combo as it's own lens, or if it would remember it as the 70-200 II. I'd say 15 feet off at 90 to 100 feet.

AFMA values are stored separately for each lens + TC combo (and with newer cameras, by serial number as well, so you can have more than one of each lens or TC type). 

Each unit of AFMA is 1/8 the depth of focus, so with 20 units you can correct for 2.5x the depth of focus - that's a fair bit of latitude in the correction.

Neuro, I just spoke to Phil at Norman Camera and he verified my field test results with the front focusing issue, and also confirmed your info that the 7D with microadjustments for the combo will be treated as it's own separate lens. He's sending me another 2X III, so it must have been beyond what would be considered normal tolerances.

What camera are you using it with?  Some of the cameras have micro focus adjustment which lets you tweak the focus and saves it for that lens and extender combination.

I've got the 7D, but to me it was so far off I didn't think the micro-adjustment would work. I also called CPS and the guy wasn't sure if the microdjustment would remember the lens/extender combo as it's own lens, or if it would remember it as the 70-200 II. I'd say 15 feet off at 90 to 100 feet. I should have tried it on my wife's 5d2 just to test that combo, but I didn't think of it at the time.

I received the 2x III for Christmas from my wife. My reasoning for wanting the extender was pretty much the same. I was looking to get to 400mm at a reasonable cost. Well, I was disappointed that my combination severely front focuses. I spoke to Canon CPS and they were happy to take a look, but since it's new, I returned it to Norman Camera. I was somewhat disappointed at their initial response. They will do their own test and let me know if they experience the same results. If they do, it will be replaced. If not, I will get a refund. I considered trying the micro-adjustment focus settings, but to me, it was so far off I didn't think that would take care of it.

Not sure if this helps, but it is my personal experience.  I’m hoping that Norman finds an obvious issue and replaces it.

Better high ISO performance, more DR, and throw in built-in GPS and I'm good.

Lenses / Re: Why would you get this lens?
« on: September 25, 2012, 05:02:42 PM »
I'll take the 70-200 f/2.8 II, then I can get to 280mm or 400mm with Canon extenders. You can't do that with the 70-300mm.

EOS Bodies / Re: Enough Full Frame Talk: Where are the 7D II Rumors?
« on: September 25, 2012, 08:49:11 AM »
So, trying to be realistic here: what features do you expect/hope to see in the 7D?

My list is short: Less noise at ISO 1600-6400; an even better autofocus; a little more weatherproofing; CF Card slot (don't care if they also include an SD, but I wants my CF); and that ability to control the camera through your smartphone using WiFi.
What makes your short list?
Everything on your list plus more Dynamic Range, and I'd be good!
So few upgrades on the current 7D?
I'm afraid the guys at dpreview will write again "this is not a WOW! camera".
Now that I've seen the "bells and whistles" on the 6D, throw in built-in GPS, WiFi, and Smartphone Remote.

Lenses / Re: Which canon macro lense 60mm, 100mm, 100mmIS, 180mm
« on: September 25, 2012, 08:12:09 AM »
When considering the 100mm IS version, I found that the tripod collar is pretty much mandatory thing when shooting from a good tripod. The lens overhang from mounting the tripod to the camera adds enough bounce to effect photo sharpness, even when using mirror lock-up and live view. Canon should include the tripod collar with the lense, IMO.

Try www.FredMiranda.com - I've purchased and sold a few items there. No eBay fees. There is a rating system for buyers and sellers so you can get an idea about a seller's reputation.  Also POTN - www.photography-on-the.net - a site only for Canon people.
