EOS Bodies / Re: What does SnapSort know about the 7D Mark II?
« on: April 12, 2013, 10:11:02 PM »
From what I read, they know nothing and have no information.  Based on knowing nothing, they gave it a rating??  They even included DXO scores ;D
 
I would give them a rating too, a 0 for faking information.

Lenses / Re: 100-400 f4.5-5.6L or 2x extender
« on: April 12, 2013, 10:01:26 PM »

 
Thanks for those. I downloaded them for careful comparisons. The 100-400mm is soft, at the level of my new SX50, whereas the 70-200x2 is noticeably sharper. For some odd reason, the software says the iso for the 70-200x2 was 250 and for the 100-400 125, not 400.

Based on your useful contribution, although it is a one off, it would be much more sensible to buy the 2xTC if you already have the 70-200 f/2.8 II as it appears at least as good the 100-400, is much cheaper and saves having to carry a second heavy lens around.

I misread the ISO in lightroom, it was right next to the 400mm focal length.  They are indeed 250 for the 70-200 and 150 for the 100-400.
 
I'm curious how you compared them with a 1200mm focal length.  Going further than a 1:1 image is going to result in horrible results.
I did not link the raw image, so your perception of sharpness is based on a cropped, compressed and possibly reduced size jpeg.

I was able to catch some birds on my front porch and take photos a few minutes apart with my 5D MK III using my 70-200mm with 2X MK II TC and my 100-400L.  The lighting was apparently a little brighter for the image from the 100-400, its almost impossible to get identical images in our wind overcast weather. The IS of the 70-200L was a definite plus. Sharpening of the images was the same, but the colors were noticibly different.
 
I don't see how you could go wrong either way.
 
here is a crop from the 70-200mm f/2.8L MK II with 2X TC  Both lenses were wide open with 1/400 sec ISO 400 exposures.

Pricewatch Deals / Re: Adorama sale

Great prices, I wonder if they are jumping the gun on the new Canon rebates starting Sunday.  The items would not ship until Monday after the sale begins.

Third Party Manufacturers / Nikon D800 Value Dropping?
« on: April 12, 2013, 04:59:20 PM »
There is a almost new D800 on our local craigslist (not a scam) for $2100.  I checked ebay and noted that there were a lot of sales in the $2200 range, some even included a cheap lens.
 
Why are people dumping them?  I was tempted to get it as a 2nd body to my 5D MK III.  I have several Nikon lenses.  Finally, I decided that I'd pass it up, if others don't want them, I won't be able to resell it a year from now without losing money.
I did buy one new last May for $3K, and later sold it for $3200 when they were hot items.   There are some better lenses now available or on the horizon, so the lens situation is not so bleak as it was.
 
I think I'll wait for a new backup body and see what the year brings.  I just bought my 6th 40D this week, its great for my product photography, but isn't capable of ISO 6400 or 12800.

Pricewatch Deals / Re: Canon USA Rebates Starting April 14, 2013 [CR3]
« on: April 12, 2013, 04:49:53 PM »
Well, of course, just as soon as I drop $2000+ on a new 70-200 2.8 IS II...  So much for the previous rumor that there wouldn't anymore rebates until next spring >:(
Next Spring??  I've never seen that Rumor! 
 
Canon has had almost continuous rebates for the last year.  Some involve only a few items and some cover a lot of items.  As long as the world economy is poor, Canon and Nikon will keep having rebates in order to keep the production lines going.  Its cheaper that way.  Shutting down a factory and restarting it later is incredibally expensive, while rebates just result in a lower profit margin, but its still profit.

Lenses / Re: 100-400 f4.5-5.6L or 2x extender
« on: April 12, 2013, 03:56:35 PM »
There is one thing in favor of the 2.8L with TC's, I was just playing with mine, using the 1.4X II+ 2X II on my 5D MK III.
 
AF is slow, but does lock in.  The IS works great, it locks the shake out even at 560mm.  IQ is definitely on the iffy side, but if you have to crop to 1:1 as in this image of a small bird from 20+ feet, it is a nice choice to have. I did  apply sharpening and other adjustments to make the image look as sharp as possible.  There was a lot of backlight, which makes it difficult.  The birds refused to pose with a better background.
 
I'll see if they will pose with my 100-400L, but I currently do not have a TC that will AF with it.

Lenses / Re: Which Lens Canon 85mm 1.8 or 135 L
« on: April 12, 2013, 02:54:17 PM »
Crop camera or FF?  There is a 1.6 difference, so any answer would take that into account.
Do you have a zoom lens to see which focal length you like.  Both lenses are excellent, the 85 is bothered with loca's at wide apertures with shiny objects.  It can be removed in lightroom.
Even with FF, a 135L has a lot of reach, I usually use mine 30 or more feet away.

PowerShot / Re: SX50 outperforming 5DIII +100-400mm
« on: April 12, 2013, 02:46:51 PM »
Even overcast days outdoors has more light than we sometimes perceive, and indoor lighting is probably poorer than we percieve.  However, none of the other models with shorter zooms had the issue that the 50X Sony and Canon had.
 
Certainly it won't beat a 100-400 inside a building with excellent lighting, but thats not where I'd use it.  Since I could not test it outdoors, I'm wondering just how long does it take for your camera to focus at 1200X after you turn it on and focus the first time?
 
I might buy one where I could return it if it doesn't perform.

EOS Bodies / Re: Digic 6
« on: April 12, 2013, 02:37:31 PM »
Canon used a different or a limited version of the Digic 5 processors for P&S cameras, so a Digic 6+ may be coming for DSLR's but is likely not ready.
 
As noted, there is no information about the microprocessor technology inside the custom chip.  Canon doesn't supply it, eventually someone figures it out, but its not published by Canon.
 
They use ARM Processors, but that covers a huge range of possibilities.  I've seen it claimed that they used Apple Designed ARM Processors made by TI in Digic 5.  ARM Processors continue to get more powerful, so its a tradeoff between power usage and performance.  Canon uses more than one digic in their high end cameras, so a big jump in processor power might let them use just one and avoid using more power.  The 1D X uses two Digic 5+ and a Digic 4 for autofocus, for example.  If one could do it, it might save power or break even..
http://www.learn.usa.canon.com/resources/articles/2012/digic_processors.shtml
 
Expect the Digic 6+ to be used in high end DSLR's probably for 4K video as well as much more sophisticated in-camera processing.

Canon General / Re: Bad Lenses
« on: April 12, 2013, 01:58:59 PM »
I've seen a number of comments in various threads about people getting stuck with 'bad' lenses that they end up having to send in to Canon for repairs, adjustments or replacement. Does Canon charge you if the lens needs an adjustment because it wasn't properly set up in the first place? Is there a quick and easy way to test the lens in the camera store to rule out most problems or will the clerk perform any tests at the time of purchase. I was thinking it might be beneficial for everybody if there was some kind of testing unit in the camera store that would test the lens's focusing, etc. I wouldn't even mind paying $5 to have the lens tested as opposed to having send into the manufacturer.
It is not possible to test a camera lens in the store for some of the more subtle issues like decentering or autofocus accuracy, and you can't use FoCal in a store either.
 
To have a lens tested, $200 or more would be a more accurate cost than $5.  Its time consuming, and a store has to pay a good camera tech fairly well.  Some tests require a lot of space, you can do it outdoors on a nice day, but the cost for a indoor facility would be high.
 
The percentage of new lenses with problems is very low, but they do happen.  Test your lens as soon as possible, and you can exchange it for another at some stores, or Canon will repair it for you.
 
Buying a used lens is a different issue because you are dealing with the possibility of a lens that has been decentered by receiving a blow or by dropping it.  The lens may look perfect, but have some internal damage.
 
I never buy a used lens unless I can return it, or unless the price is low enough to allow me to have a average repair done.

Lenses / Re: Keep my 70-200 f/4 IS?
« on: April 12, 2013, 01:46:52 PM »
Mine is up for sale now after I received my refurb about 4 weeks ago.  I don't use 70-200 enough to justify two lenses, even though the f/4 is fantastic.

« on: April 12, 2013, 01:38:00 PM »
What data are you actually looking for?  Just photos taken with a particular lens? 
 
In digital photography, the body uded has a effect on the IQ of a image taken with any particular lens, and sometimes a large impact.
 
If you are wanting to see what a lens can do on your body, you need to filter for that.

Lenses / Re: 2 filters jammed together
« on: April 12, 2013, 01:33:49 PM »
I just used my filter wrench a few days ago, I bought a 50mm f/1.8 MK I lens with a UV filter on it for $25, but the filter was stuck due to a tiny ding in the filter thread on the front of the lens. A rubber band would not do it, but I have a heavy duty filter wrench which did the job.   I removed it, and used a thread straightening tool, and it was fine after that.

Another vote for 50mm 1.4 and 85mm 1.8.

Spokane, question: when did you start seeing these people?

I ask, because it wasn't before my first Canon IS point-and-shoot before people thought my shots were professional.

I'm one of those people that 'buys up' and is then disappointed, but ultimately gets used to it; my Tamron 24-70 just 'let me down' (I wasn't doing things right) on it's first serious use.  I wanted f2.8 DoF, but my son was running in and out of the field too quickly. All of them that I stopped down to f4.0 looked great. 

You live and you learn; as long as you're willing to learn, you'll be fine.

I've purchased dozens of cameras and lenses, probably hundreds, locally from Craigs list or estate sales or garage sales for many years.  I use them a bit, keep the ones I like, and resell the others.  Then if something better comes along, I sell the one it replaces.  I make sure when I buy something that I can resell it without danger of losing money.
 
 
For many of the rebel DSLR's I've bought, a high percentage were from buyers who put them away in a closet after using them a month.  Then, they sell them after another year when they realize that they are never going to use them.  By contrast, That is seldom the case with the XXD or higher cameras.
 
The issue is that some new buyers don't know what to expect from a DSLR, and might use a little help.  Most all of the users here knew what they were getting into, but even so, we see one or two a week asking for help. so I thought it might be nice to have a FAQ for them to read.
 
 
I think your example of stopping down to get more depth of field on a slower focusing beginnner type camera/lens combination could be worked into a lesson learned.  Something like:
 
"Canon Rebel DSLR's are meant for beginner level photographers and do not have a pro level ability to focus sharply on fast or erratically moving subjects like soccer players when used with a wide aperture shallow depth of field lens. 
 
One way to work around this is to close your aperture down to a smaller amount, f/4 or f/5.6.  You will get more depth of field, and find that the camera can better keep up with sharp focus of moving subjects."
