Photography Technique / Re: Is RAW worth it?
« on: August 25, 2014, 07:59:41 PM »
Yes,
sure jpeg  is good for some usages but having a raw can really save you in trick situations.  I one went out a took around 700  jpeg  photos.  It is sometimes hard to Judge the quality of the image in sunlight.  I got home and they were all slightly over exposed by 1/3 to 2/3.  If I had raw this would not have been a problem.  That was when I found out that my camera always over exposed with that particular lens.   The images were somewhat recoverable but I had to boost saturation to much for my taste.

Now I just shoot Raw+jpeg.

EOS Bodies / Re: Do Sensors Make the Camera?
« on: August 25, 2014, 07:43:58 PM »
In some cases yes.  But in others the system as a whole is more important.   For the most part Canon builds some of the most reliable and consistent cameras on the market.  After you become familiar with their cameras and lenses you are almost guarantied consistent results. For many pros consistency is the most important factor. 

I understand that many are satisfied with Nikon cameras but personally I cannot stand their layouts. 

I can get results with my Nex 6 that are flat out impossible with my 60D because of dynamic range. I love the ability to utilize legacy glass with actual focusing aids. But the Sony also has some quirks with color balance. I have seen images shifted to completely magenta in between normal shots. 

The 6D is much more capable when it comes to dynamic range than the Crop canons I have used. I have not tried taking a picture of a black cow with a white face in full sunlight with my 6D.  The Nex 6 simply take the picture boost black in post to recover highlights.  The 60D you either blow out all the detail in the white face or end up with a black blob of a body.  So yes the sensor matters some.  But for the most part all current cameras have trouble with my cow test. 

The truth is the best sensor in the world is useless with out the camera system surrounding it to support it. And Canon as the best system as far as I am concerned.

EOS-M / Re: FD lenses
« on: February 08, 2014, 09:56:01 AM »
I have the following that I use fairly reguarly on my Nex6
  • Canon FD 24mm f2.8 S.S.C.
  • Vivitar C/FD 28 f2.5
  • Canon FD 35mm f2 S.S.C.
  • M42 Pancolar 50mm f1.8 Carl Zeiss Jena DDR
  • M42 Super-Takumar 50 f 1.4
  • Canon FD 135mm f2.5 S.C.

The 135mm f2.5 is good but shows purple fringe in spectral highlights such as water drops.

I also own  a Canon FD 50mm F1.8 S.C., Canon FDn 50 3.5, Macro and a M42 77M-4.  The Canon FD 50mm f1.8 is the last 50mm lens that I would choose to use.  It is not that it is a bad lens.  It is just so boring.  I kinda have the same problem with the EF 50mm 1.8.  The act about the same.  They both suck wide open (compared to some of my other options) have excellent sharpness stopped down especially in the center. 

But so do all the other 50mm lens I own.  It has a terrible minimum focus distance compared to the Zeiss.  The Zeiss and the M77-4 have swirl bokeh wide open and tons of character.  It cannot go as wide as the  Super-Takumar.  If on the EOS M the EF 50 1.8 I own has auto focus.  On the Sony my the Sony E50 1.8 can be used wide open and has Sony IS. 

The truth is the  Canon FD and EF 50mm f1.8 lens are my last chose for 50mm lens period. 

Personally I prefer using the Sony Nex to the EOS M for all old lens.  The Sony focus peeking works better then ML focus peeking.  I have noticed that all of the converted lens are a little week at infinity focus.

Lenses / Re: Is There a Definitive "Best" Landscape Lens for Crop?
« on: February 01, 2014, 11:15:58 AM »
There is no such thing as the ultimate landscape lens. 

I have never really liked the distortion on the Ef-s 15-85 mm from 15-20mm.  And generally changed to my Sigma 10-20mm f4-5.6 when going that wide.  That said I prefer 15-55 for pure landscape.  Unless there is something in the foreground to act as the subject of the seen I  rarely go wider.    I have used a 70-200mm for landscape when there was something at a distance that was interesting.  For the most point I consider landscapes with an ultra wide and no subject "Ultra-wide abuse".  In general the landscape is so small that the hole thing becomes boring. Especially with a large empty foreground.   

That said some of my favorite landscape pictures have been taken with an Ultra-wide with a subject in the foreground.  Such as a tree growing on the side of the Grand Canon, wave crashing into a huge rock with the sun setting in the background.  I think that the best Ultra-wide IQ wise on a crop is the Tokina 11-16 f2.8.  The canon 11-22 is more versatile and holds its value better.  The Tokina is really a specialty lens with a limited focus range.

I bought the Sigma 10-20mm f4-5.6 after extensive review on a site that compared the canon, Tamron, and both sigma 10-20mm's.   The site had full  size images at a variety of focal lenght and through the entire f stop range of the lens.  To me visual the canon was a little better IQ that the Sigma f4-5.6.  The Sigma f4-5.6 was better stopped down than the Sigma f3.5.  All of them were better than the Tamron. They were all extremely close.  So it is hard to go wrong with any of them.  The Tokina however stands out for the f2.8 but was not in the review.  I could not justify the priced difference between the Canon and the Sigma to buy the Canon.  Also 10mm vs 11mm is a big difference.  I was vary happy with the sigma until it went for a swim with my old 60D. 

The biggest  thing with the Sigma is that it focus different than all of my other lens.  It works best if you turn on all focus points.  If you use the center focus or an outside edge focus point then it will stop trying to focus the second it a achieves lock on the center point.  The dept of field is such that it may be at the edge of the dept of field.  This means that using center only could lead to soft out of focus corners.  Using a edge focus point could lead to a soft out of focus center.  I do not think Af micro adjustments could fix something like this.  It is more of a function of the focal range/dept of field and sight lens distortion.  But once you figure this out it can easily be accounted for.

But if I had not gone full frame and had not bought the Nex6 and a 10-18 F4 I would be buying a Tokina to replace my Sigma that is beyond reasonable repair.

Buy the camera that suits your need best. 

Personalty I would go for the 70D or a Sony A7r.  While I would love to buy the Canon 5d III I could not afford the lens I would want to go with it for wildlife.  The new Tamron 150-600 may change that.  The 70D would fill a immediately need for a fast focusing crop for wildlife.  I also wished that the 6D had a tilting screen it is the only thing I miss from my 60D. 

For some people who shoot weddings and events it is better to have two identical cameras.  I do not have this need so I buy cameras to shoot different types of photography. 

I bought the 6D for a general purpose/Low light, ambient lighting camera. I do not need a second camera for this.  A canon 5d III would effectively replace it.  I still use my Nex6 a great deal. A Sony A7r would be a replacement for the Nex6  using vintage lens and a backup landscape camera for the 6D.  I only use my 60D when seriously range limited or to use Magic lantern.  I have not installed ML on my 6D yet.  I plan on buying the new Tamron 150-600mm after the initial demand tapers off a little. 

I do have a want for a fast focusing crop camera with a 1/8000 second shutter.  I am still waiting to see what is a replacement for 7D.

Some time latter in the year I plan on replacing my Nex 6 with a Sony a7R.  Having used the Nex 6 for over a year now I can say that Sony Emount system is a good complement for Canon users.  Canon lens are a little cumbersome when it comes to auto focus on a Sony.  But the focus peeking for manual focus lens is fantastic.  My Nex 6 is the easiest camera to manual focus I have ever used. 

It will only be good for standard landscape to around 135mm anything longer the logistics will get brutal.  But still better than a normal Canon M.  The battery grip helps ergo. 

I plan on using it for landscape and standard photography mostly with vintage lens.  But I am keeping my Canons for moving subjects.

Lenses / Re: zooms vs primes for landscape
« on: January 26, 2014, 07:20:56 PM »
I wish canon makes a decent 20mm lens (Zeiss cost too much money). 

I agree it is a shame the 20mm Canon is so bad.  I am tempted to try out the VoigtlÃĪnder Color Skopar 20mm f/3.5.  Sounds like an interesting lens.    But to be honest I think I will wait until after I buy a Sony A7 and get one of there Leica M mount lenses.

I don't know how I missed this response.  Neuro explains perfectly the practical things and why you need Tilt-shift for landscape.  Although I would add that the f1.4 would be beneficial for landscapes with Milky Way in the absence of star-tracking tripod mount.


The problem is that for most the 24L II has unacceptable Comma wide open.  Everything I have read suggests the Samyang 24mm 1.4 would be better for that.  That is the primary reason I suggested against the 24L the one case where 1.4 would be a benefit is its largest weakness.

Third Party Manufacturers / Re: Best Nikon DF Review! By Fstoppers.
« on: January 26, 2014, 06:47:13 PM »
There is clearly a demand a retro designed camera.  Some people like there photography gear to look like stylish old school cameras.  But they want many of the modern conveniences of a modern camera.  I admittedly am one of them.   I enjoy the act of taking photos.  The feel of the camera as I manual focus and compose the image.  As I see it the modern Canon cameras feel and look like soulless tools.  They work with clinical precision.  To me modern cameras like the D600 have all the ergonomics of a brick rapped in tin foil.  And a button layout of a schizophrenic. 

I like buttons, nobs, control dials and levers.  I freakin hate touch screens on my camera.  I am all for manual control.  It sounds like I am in the DF target audience.

The problem with the DF is not one of concept.  It is definitely one of execution.  For the DF Nikon did not have constraint in mind.  It is in you face with the rotary dials.  Over the top with price.  It also looks like you would spend more times playing with the dial then taking pictures.  It looks like a complete mix of all the worst parts of digital and manual cameras combined. 

In the most part what would work best is a new digital take on a  classic design.  Not a old school take on modern camera.  By replace every modern feature with a manual control dial they created a fashion accessory instead of a camera.  There is something to be said for ease of use and access to controls.  But this thing like all of the newer Nikon's I have looked at is a fidgety camera.  I am one to spend too much time fidgeting so I try to stay away form fidgety cameras.

I find more appeal in the OMD,Sony A7 Fuji cameras.  I think Sony A7 would look sweet if they made a silver and black version. 

I would likely buy a modern version of the Canon AE1 style camera.  (It would need to have a updated shutter)  But if Canon made a camera in this segment I wish they would make the effort to keep some of their modern elements and integrate them into a classic design. 

But I think what I really do not like about the DF is that:
  • It is a Nikon
  • It has insane nob layout
  • It lacks clean sensible layout of manual controls
  • It has a insane price
  • it is a Nikon I am allergic to Nikon

Canon General / Re: Review: Canon EOS 17-40 f/4L by DxO Mark
« on: January 26, 2014, 03:39:02 PM »
I have in general been avoiding all DxO Mark threads.  I find the lens reviews at best a comedy of errors at worst egregious miss characterizations.  They sometimes bash lens for flaws of the cameras they are testing it on.  All in in all it is just better to ignore them. 

The only camera they have tested the Sony E10-18f4 on is the Nex7.  Spent a huge amount of time complaining of soft corners and color fringing.  The Nex7 has a well documented problem with wide angle lens because of a micro-lens design flaw and the never once mention that.  They have also never bothered to test it on any other Sony Nex cameras.

The Sigma DN 19 and DN 30 have only been reviewed on the absolute worst m43 camera.  They have terrible scores but are fantastic lens for the price. 

Last time I checked the Tamron 28-75 had higher marks in Both the Sony and Nikon mount.

If you buy a 17-40L as a standard zoom for a crop camera now that plenty of EF-s and other crop options are available, well, you're doing it wrong.  It's an ultrawide zoom for full-frame.

+1 - and that's the point of comparing it to the 18-55/3.5-5.6 IS kit lens or even the 17-55/2.8 IS.  Compared to the 17-40L on APS-C, the former delivers not-too-different IQ and the latter delivering better IQ (and an extra stop of light, a broader range, and IS).  Yet, many people recommend getting the 17-40L 'in case you go FF maybe someday,' which I think is pretty foolish unless 'someday' is next month.


Ah yes those people who have a cheap entry level Rebel camera with a 17-40L stuck on the end! Yup I agree, unless your "other cameras a FF" and currently out of action you have no excuse! Too cheap to buy a FF camera but has enough to show off with an L lens! (A cheap one at that!) you're foolin no one son!

I've read that it is better to get good glass on a cheaper camera than the cheap glass on an expensive camera.  So now the person who takes that advice is being made fun of?

I am a proponent of using good glass on a cheep camera but it has to make sense.  The 17-40L on a rebel is a waist.  The camera can take much better pictures with a good EF-s lens.  The 17-40L lacks IS it is relatively slow for crop.  If you are going to get a full frame L lens for a crop camera get one of the 24-x lenses, and then buy a Ef-s Ultra wide.   24-x is fine for an outdoor zoom in wide open places.  Save buying the ultra-wide full frame lens for when you buy a full frame camera.

All of the telephoto lens make sense.  So a 70-200L or 70-300L should be on all Rebel users list if they plan on moving to full frame.

But that is just my opinion.

I get your jokes... and they are funny... but sometimes taking the "wrong" lens with you can help you to produce some really unique images.

Tell me if you take the "wrong" lens and produce "unique images" is it really the "wrong" lens?

« on: January 26, 2014, 01:25:06 PM »
I expect a L refresh sometime later.  I just cannot see a 135mm f2.8 L IS being a big seller unless it was a macro. Most looking at the 135L are in it the the bokeh.

The current 100/2.8L IS Macro has amazingly good bokeh.  I'm guessing that a 135/2.8 IS (L or non-L) would be just as good, if not better.

The 100L IS has good bokeh.  But I would not say it is even in the same league as the current 135L.  If they made a 135/2.8 IS it would likely have as good or better bokeh than the 100L.  But it will not be in the same league as the 135L.

The 24 f1.4 is an appalling choice for a 24 mm dedicated landscape lens. The TS-E24 MkII is probably the best current 24mm 135 format lens available, and it is uniquely orientated towards landscape work. How many landscapes are you going to shoot between f1.4 and f3.5?


An appalling choice?
Maybe we should all switch to Nikons high MP camera, then things like vignetting and distortion wouldn't even exist.

Anybody that sees another 135 format as a "better" choice is so divorced from my understanding I am glad Neuro has taken this one. By your logic we should all be shooting 8"X10" and drum scanning.

Your troll's job is done. You can go away now and Neuro can take this one.
He can debate how appalling the 24mm f/1.4 II is for you.

The 24 f1.4 MkII is a superb lens, but it has zero functional advantage over the 24-70 f2,8 IS as a landscape shooting lens, zero, none, nada. For somebody wanting a dedicated 24mm LANDSCAPE lens suggesting the f1.4 is pretty terrible advice, even worse considering Canon actually make probably the best 24 mm LANDSCAPE orientated lens in the world, the 24 TS-E MkII.

P.S. I am no troll, and I don't suffer fools or their "advice" easily.

I agree the 24 f1.4 MkII is a fantastic lens but I would not get it for landscape.  The only time that 1.4 could be useful is for astro-landscape but it has been reported to have coma so it is not good for that.  It is a rather large lens if the goal is "24mm and to stay light" get the 24mm 2.8 IS.  If not get the 24-70 f2,8, TS-E 24mm L or Zeiss 21mm. 

I would chose plan 2.  I wish I had bought the Canon 70-200f4 IS instead of the non IS.   I chose to supplement my 70-200f4 with a Tamaron 70-300 f4-f5.4 VC when IS is needed.
