EOS Bodies - For Stills / Re: 5D Mark II with selector dial mod
« on: October 30, 2014, 11:01:49 PM »
Yup.  I never had a issue with my dial rotating on my 5D MK II or 7D, and don't like the lock on my 5D MK III.  I have very little feeling in my fingers and find it difficult and frustrating.

Another issue.... many of the early supplies were "kits only".... so a lot of us have to wait for the "bodies only" boxes to arrive. My supplier, "Samy's"/California, USA have the kits now, but no "body only" boxes. Hopefully they will get a body only box in quickly or break up a kit for me either tomorrow or Saturday. :'(

That always seems to be the case, kits are available before bodies only.  If the kit had lens that was in demand, that might change.  There is nothing wrong with the 18-135 except that it better matches a rebel.

I noticed that they had it listed yesterday, but thought it would be gone today.

I would expect that there are many places that have the camera in stock.  I think that Canon has built up a really big stockpile this time, and DSLR's are a bit of a hard sell, money is tight, so many are just not able to afford them.


Let me turn this around for you.

You've got a production line manufacturing lenses and each one is different at a level that no human can detect (this is true for Canon lenses too.) From that production line you're advocating that someone compares each lens with each and every other lens to find which is best. If you've decided to do that, how do you know that the 101st lens isn't better than the preceeding 100 that you decided to compare or that the 102nd isn't better again? Once you've decided to "find the best", where do you stop in terms of comparisons? You could seriously do your head in (and the heads of those around you too.)

It is thus far easier to pick a lens at random and send it off for review. Afterall, that's what the review should show: what a random sample of the production output is like.

A review should indeed show what a Random sample looks like, which is why virtually all the lens testers purchase, rent, or borrow the lenses they test.  DXO, DPR, (Long List) .... all the popular testers but one.

It is actually not necessary for Sigma to do a complete exhaustive set of tests in order to find a good lens.  All those carefully tested for characteristics like Coma, CA's, curvature of field, etc are already baked into the design.  Manufacturers do a exhaustive analysis of the key characteristics that can be checked to reveal that a lens meets design specifications.

A lens cannot be better than the design, so there is no such thing as picking a perfect one, just picking one that happens to fall on or above the average. 

That's quick and easy.  Unlike poor internet testers, who must do everything slowly and carefully, as well as discover characteristics that Sigma already knows about,  Sigma has millions of dollars worth of automated test gear that can run a test quickly.

What I'm saying when I say that sigma has tested the lens to pick a good one, means that they have rechecked those key characteristics, For example, making sure that there is no decentering (commonly found in zoom lenses straight off the production line) among a few other likely tests.

Just checking a very few things will ensure that the lens is as good as it can be, so Sigma delivers one to a tester who then tests the lens for many characteristics that sigma does not publish, but knows about based on the design.  The only thing is that's its not a random lens as found on a sellers shelf.

No, all you do is pick twenty or so lenses at random, test them and pick the best ones, and send those out to reviewers. I'm sure manufacturers have time for that. They're not looking for the very best one they have ever made, just one of the better ones. If there is significant variation, this makes a big difference.

Huh...then why did they send lenstip a 150-600S that looks so bad and FF edge at shorter focal lengths?  And why did Canon send lenstip a 70-300L that was bad at FF edge for 300 mm compared to what was seen with other reviewers.

There might be some selectivity, but I doubt it is very robust, if it exists.

Probably because it was one that fully met their internal specifications.  A $2,000 lens is not going to match a $12.000 one, it will be a compromise.

Contrary to those who seem to believe that a huge company with rooms full of lens testing equipment don't know how to test a lens in a short period of time, I can tell you that its possible.

Lenses are constrained by their design, so its not possible to pick one that's better than the design, all that is necessary is to give a 2nd look and make sure it meets the design specifications, and is not a dud.  Failing to do this would be pretty stupid.

Virtually every lens tester refuses to accept lenses from a manufacturer for their testing, and rents, buys, or borrows from a dealer.  Lenstip also often borrows lenses from dealers.

I've been in the industry for 30+ years, and have seen many carefully prepared samples submitted to my lab from manufacturers, and then seen the real product.  That's why we always grabbed random parts from incoming lots and gave them a careful testing. 

EOS Bodies - For Stills / Re: 7D mark ii CR2 codec
« on: October 30, 2014, 04:23:23 PM »
Early adopters have to use the Canon software.  Eventually, over the next several weeks or months other software will be updated.

First, the companies have to get a camera, then develop the software.  Windows usually updates codec's every 6 months or so.

Lenses / Re: missing reviews of 400mm f/4 DO IS II
« on: October 30, 2014, 10:37:13 AM »
Don't expect Canon to be passing dozens of these around to reviewers like the 7D MK II which is intended for the general public.  Only a few 400mm D) II's will be produced as compared to consumer bodies. 
The lens is likely difficult to produce, DO technology still requires a lot of magic.  Don't be surprised if the deliveries are delayed a few months.

Software & Accessories / Re: What accessories for 7d Mkii?
« on: October 29, 2014, 10:53:46 PM »

I'm surprised to see so many suggesting a battery grip. I've always thought they looked too bulky, plus most of my work is in landscape mode, but I'll have to try one sometime!

I'll check out the other products that have been suggested.

Thanks everyone,



A grip on a 1 series is rock solid, but on a 7D, I'd pass.  You do not hold a camera with heavy lens by the body / grip combination, you put a hand under the lens to support it.
I've had a lot of grips, and took them all off. 
Unless you have a specific need such as portrait orientation or extended battery life where you can't easily change a battery, I'd pass.

Lenses / Re: DO you correct lens vignetting when sot wide open??

I rarely correct for it, since I end to crop a lot which pretty well removes it.

Software & Accessories / Re: DxO OpticsPro 10 released
« on: October 29, 2014, 09:41:55 PM »
The issue I had with version 9.5 was the extreme slow exporting to jpeg ot to lightroom.  The lack of a export to Smugmug was also a factor.
I'll try ver 10.
I presume that ver 9 will not be upgraded to work with new camera models?

I have a MANFROTTO 190xPROB and a 496RC2 , solid gear no PLAY , looking for a VIDEO head for possible that POD and or  just another  Tripod and head. Seen a  Combo Movie / photo head from Manfrotto a review  shows the arm and Head with some  PLAY and other fall downs overtime, just want smooth transitions and Ease in ease out pans/tilts seems like a full on HEAD is in order. (budget 500ish CND)

Any suggestions are welcome , thank you guys.

I doubt if you really mean  "The Best" unless you have $15,000 or $20,000 to spend.  You can usually do pretty well for $5,000.  Otherwise, you are going to have to deal with increasingly jerky pans as the quality of the head drops.  For a low end but professional level head, the $1500 Manfrotto 526 is reasonably good, but you need a bowl type tripod to go with it, so its still way out of your price range.
In your price range, a Manfrotto 504 HD head is the best for under $500.  http://www.manfrotto.us/504hd-pro-fluid-video-head-75 , but you still need a tripod to match.
If you are not actually doing video for a living, get the best you can afford, and just live with jerky pans.  Otherwise, consider renting a suitable tripod / head.
Sorry for the bad news, but when mentioning the "Best", its totally out of reach for most of us.  I have a $200 502 HD video Manfrotto head with flat base, and live with the jerky pans.

I haven't seen a issue, and mine does not loosen.  Even if it did loosen, it takes several complete turns of the threads to disconnect, and if it fell off "moments" after securing it, its hard to imagine it turning that many times.
I do check mine visually as well as making sure its tight, since a cross thread can tighten a screw with only a partial turn, and it will easily separate. 
The weakness in the system comes when users must repeatedly screw the attach point into their camera or lens base, and it just takes one cross thread when you feel it tighten to cause the issue.
It would be nice if everything were foolproof, but, as they say, fools are just too ingenious.  (Not talking about the OP).

Lenstip has reviewed the Sigma 150-600 S.

Be aware that they received the lens they tested from Sigma.  To me, receiving a test lens from the lens manufacturer means that:
1.  The lens has probably already been tested by the manufacturer, and selected as being one that is the best possible. 
2.  You will never be able to get one as good as the one tested thru a store.
3.  Its also implied that a poor review means no more free lenses to test, so there is pressure applied to go easy on any flaws.  Even DXO does not take manufacturer supplied equipment, but purchases or rents the test items, and usually they test multiple items.
Those may or may not be true, but should be considered when reading the review.  Independent review sites do not take freebies from the manufacturer of the product that they are reviewing.  Its like a Automobile Magazine that not only gets a car to test, but depends on advertising.   

EOS Bodies / Re: Modular DSLR Coming from Canon? [CR2]
« on: October 29, 2014, 12:09:25 PM »
Cinema cameras are modular, but also extremely expensive.  Each part has to be engineered with a reliable way of connecting / removing it, as well as a standardized communication channel among the electronics in each part.
While a 4 or 5 or 6K Cinema camera can take competent stills, the price tag of $60K + for a complete setup does not lend itself to still shooters.
Modular Cameras are heavy and bulky, but that is not a big issue for Cinema, they are used to large cameras.
It could have a body with sensor, external battery module, lens adapter modules (EF, PL, ect), Viewfinder, recording module, sound module, display screen, focus puller module, and a ton of stuff used for cinema.

Lenses / Re: Is this 70-200 2.8 II worth buying?
« on: October 29, 2014, 11:08:10 AM »
I paid $1600 for mine as a Canon refurb about 1-1/2 years back. 
Note that on the below price history graph, the price has dropped more and more each year starting around black Friday.  You can form your own opinion as to what will happen this year, it depends on inventory and sales, I doubt that even Canon knows how low they will go.
