Lenses / Re: 24-70 f/2.8ii made me a believer
« on: February 24, 2015, 11:24:46 AM »
After having 5 or more of the old version, and liking my 24-105L better, I really like my MK II lens, and reluctantly sold the 24-105.

The price of the 24=70 is better now, but its still up there.

I now have three zooms that are very good, the 24-70 II, the 70-200 II, and the 100-400mm II.  I've kept a old Tokina 17mm f/3.5 prime that I like, and it was cheap.  Along with my 100mm L, I'm pretty happy.  My 24-70 is the workhorse.

My next purchase will likely be a new body in the next year or two.

As always, its interesting to see the comparisons of the lenses in a way that no other reviewer can show us.

I will be interested in seeing the results from the new Canon ultra wide zoom.  They probably will not be spectacular due to the extreme wide angle, but at the price, they should be no worse than these.

I gave up on buying ultra wide lenses, because I have no talent for using them, and no matter how good a lens is, the talent of the photographer is 10X more important.

Lenses / Re: understanding "fastness"
« on: February 23, 2015, 08:14:41 PM »
Thanks, that is very helpful.  I knew the 70-200 2.8 ii had far more elements, but I guess I falsely assumed that each element would transmit at least 99.9% and that the cumulative effect wouldn't be that great. 

Even though the 6d has comparatively good high iso performance, between my fondness of hand-holding and inexperience at post-processing, I am still trying to use the lowest iso possible to allow me maximum room for error in over-sharpening without introducing a bunch of noise.

I can see why manufacturers would not want to publish their T numbers but I've found the info on dxomark, so that will be handy going forward. 

70-200 2.8L ii = 3.6T
50 1.2L = 1.4T

Groovy.

Canon gives "T" stops on their Cinema lenses just like other lens makers.  The definition of a aperture is a physical opening and does not tell you how much light is passing thru the lens.  A T Stop does tell you.

If you read this section from Wikipedia, notice that the aperture is physical and does not specify how much light is passing thru the lens.

"The lens aperture is usually specified as an f-number, the ratio of focal length to effective aperture diameter. A lens typically has a set of marked "f-stops" that the f-number can be set to. A lower f-number denotes a greater aperture opening which allows more light to reach the film or image sensor. The photography term "one f-stop" refers to a factor of √2 (approx. 1.41) change in f-number, which in turn corresponds to a factor of 2 change in light intensity."

I have both the 7DII and the 5DIII and this lens.

I've had problems with it hunting on the 5DIII but I'm not yet sure if it is my technique or not.

Focus is fast on the 7DII but I'm getting soft images most of the time.  I can't match anything like
the sharpness of this image (7DII, 400mm DO mark I, 1.4x III, hand held):

Did you 600mm owners have to do the front/back focus adjust with that lens (I've never done it with any lens, I typically get good results without it).

I get better results using live view, this was live view (so the mirror was locked up):

http://www.mcvoy.com/lm/moon.jpg

If I tried to take that same pic without the mirror locked up I got nothing but blur.

So far, this lens is pretty frustrating for me, I get good results with the 400mm & 1.4x (which is 560mm)
hand held; I can't match those results tripod mounted.  I use a gitzmo and a gimbel (knockoff of the
good one, wimberly I think?).  I'd love to be told how to use this lens, so far I'm sucking.

If live view gives sharper images, you very likely need AFMA.  I AFMA all of my lenses as soon as I receive them.  Its a good way to determine if there are any issues.

I had the original EF 600mm L, and AF was fast on any camera body, and I do not recall issues hunting for focus.

Macro / Re: Playing with kenko extension tubes
« on: February 23, 2015, 07:54:49 PM »
I doubt if "Most" photographers even own extension tubes.  They come in handy occasionally to allow close focus of a lens, and even a macro lens can focus closer using them.  If a person is going to do a lot of Macro photography, Macro lenses are almost all excellent lenses, so they can be used for all types of photos.

After a Macro lens, my first choice would be a TC because you are not limited as far as near and infinity focus, AF works well, and you get more magnification.  They are also more expensive, but being more useful is worth it.

I've used a extension tube on my 100mmL, and it works, but not really well.  Canon TC's don't work with the Macro, and Kenko's latest hang all recent Canon bodies with the 100L and AFMA turned on, so they are not a option.

I'd also recommend trying different focus point options in your 5D MK III.  For example, using the reduced center point can make low contrast objects difficult to focus on, but enabling surrounding points will help with this.

EOS Bodies - For Stills / Re: I just want a stills camera.
« on: February 23, 2015, 12:06:48 PM »
A stills only Camera will be a niche camera that only appeals to a few buyers.  Nikon found this out with the DF.  It does not take better photos than a camera with video, does not cost less, and has little resale value.  Buyers looked at it and said "Whats the Point?"

For those who want stills only, get a DF.  Canon has and probably will continue mass marketing cameras, their entire production and marketing distribution system is setup for it. Its what they do best, turn out a good, reliable product that may not be the best, but costs less and still makes a bigger profit.

So far, Sony has not been able to match the low cost of production that Canon has, so their profits are slim.  They are planning on going all out with sensor sales and are making big $$ on those.  The market forcast is for sensors to be integrated into everything, from Cameras, and Phones to cars, TV sets, Microwaves, Games,
Houses, Everything.  All products will be smart products and recognize the owner, its going to change a lot of things.

Photography Technique / Re: POLL: Do you wide-screen frame/crop?
« on: February 23, 2015, 11:56:09 AM »
Much of the time, I cannot control a scene, so I crop to fit the subject.  Since I shoot RAW, cropping in the camera makes little sense to me, however, when needed, a person can purchase a focus screen with guide lines for various or specific aspect ratios if they want to frame to a certain aspect ratio.  This gives them the ability to easily recover from partially cutting off a subject or cropping tow tightly, or correcting the level.

I'm sure that there are certain types of photography where specific aspect ratios are required, like printing portraits on 4 X 6 or 8 X 10 paper.  In cases like 8 X 10, using a different aspect ratio makes sense.

EOS Bodies / Re: Possible Canon EOS 5D Mark IV Spec Talk [CR2]
« on: February 22, 2015, 12:57:03 PM »
This is just one of what is likely several test cameras on the streets, and, it might be a year old!

I am one who would get a 1D X instead as well.  Prices for gray market models have dropped to very close to the price of a new camera, and it uses CF cards, so no need to spend $750 for a couple Cfast cards.

Lenses / Re: which telephoto for travel?
« on: February 21, 2015, 08:57:32 PM »


I'd still advise you to switch this for a 70-300L - roughly same iq and aperture, but longer reach and shorter pack size. I know the switched zoom/focus rings and direction can be an issue to some, but imho you might get used to it unless you shoot with two bodies in parallel.


+1. (We agree sometimes)

Lenses / Re: APS-C 60mm or 100mm macro lens?
« on: February 21, 2015, 01:19:41 PM »
If you are worried about shaking, then you are trying to handhold a Macro shot??  IMHO, only the 100L allows you to consistently handhold the camera at near macro distances due to its hybrid IS.

Oh my, my favorite fallacy - my observation is that IS near 1:1 is next to useless, though it makes soothing sounds so you think it probably does something :-)

As for the non-L (I've got both): It's nearly as fine as the L, but not sealed and a more nervous bokeh which actually can be more interesting than the "boring" smooth L. As the non-L is rather expensive in comparison, I'd go for the L or get the non-L used.

I and many others use the 100L at MFD handheld, so its not a fallacy.  Perhaps your IS is defective?  Its certainly not easy, you need to hold very still or use high shutter speeds, but it works.  I could have never taken those images handheld without the IS, I've tried with my other 100L Macro's.

There is little doubt that use of the proper tripod and head will give better results, but when I see a bug or item that I only have seconds to capture, I can now do it by grabbing the camera, lens, and snapping a few quick shots.  I certainly do not get 100% keepers, more like 70% under those conditions.

Canon General / Re: Canon Mail In Rebate Question
« on: February 21, 2015, 12:55:30 PM »
Canon wants a physical address, no po boxes or ups stores.  Those are often used by scammers, and they learned that quickly.

There should be no issue as long as its a physical address such as 12345 W St as opposed to PMB or PO type addresses.

Adorama was giving free spills and drops insurance (1 year) with new high end lenses, depending on where you bought the lens, be sure to check.

Everyone seems to think you are asking about the 100mm L, but I think you are referring to the 100mm f/2.8 or the 100mm f/2.8 USM.  There are three Canon 100mm Macros in existence, but the non USM version is long discontinued.

Of course, the 100mmL is wonderful, Ilve had all three 100mm Macros. 

If you are worried about shaking, then you are trying to handhold a Macro shot??  IMHO, only the 100L allows you to consistently handhold the camera at near macro distances due to its hybrid IS.

Otherwise, you may find that a macro rack and tripod will be on your shopping list for a non is macro.   That evens the price up a bit.

Here re a couple of hand held shots with the 100mmL (I really never was able to use my other 100mm macros for macro distances handheld)

EOS Bodies - For Stills / Re: 5D mark ii or 70d
« on: February 21, 2015, 12:35:44 PM »
It is simply a matter of what your usage is.

The 70D had autofocus for video, while the 5D MK II has better low light response, and will give better IQ and wider angles given the same lens.

If you find that you are using telephoto lenses a lot, the 5D will appear to be much wider, so you will need a longer telephoto lens to get the same view.

Autofocus is not a issue for me, I've taken many action photos with my 5D MK II with great results.

I looked at new 70D's several times, and I wanted to like it, but it just turned me off each time.
