EOS-M / Re: EOS M Accessory question
« on: September 18, 2014, 09:58:52 PM »
I bought and sold an EOS M + 22 + 18-55 + adapter.  Then when the second fire sale (at $250) came around, I snagged the M + 22 again and added the adapter as well.  When I had it previously, about the only lens I mounted on it was the 40mm.  However, this time around I have additional lenses and find 2 that work really well with it.  I use the EF 35mm f/2 IS USM and the EF 50mm f/1.4 USM both work wonderfully on it.  The EF 85mm f/1.8 also works well but due to the longer focal length I find it slightly more difficult to compose images and locate my subjects - it's not terrible, but it's not great either.

For me, the 22 + 35 IS + 50 is a GREAT, LIGHTWEIGHT, small(ish) walkaround combo.  Personally, I find zoom lenses on the M to be cumbersome and I don't really like them.  Both the native 18-55 and adapted zooms.  Adapted zooms are worse.  Probably a personal preference.  And note I haven't tried the 11-22 or the 55-200.

I agree, a fast 50 on the M will complement the 22 nicely. Much like a 35-85 combo on FF.
I didn't really like the 50/1.4 though (bought and sold it 3 times), so I am thinking on the FD 50mm lines.

If that is the case go for a M42 mount 50mm.  I could not tell any real optical difference between the FD 50mm 1.8 and the EF 50 1.8.  I expect the FD 50mm 1.4 would be the same.  I have thought about tracking down a FD 55mm  f1.2 that may be worth it.

EOS Bodies / Re: Canon 7DII - Did you preorder?
« on: September 18, 2014, 09:34:20 PM »
Canon usually has enough cameras on had that pre-order is not realty necessary.  I am gong to buy the Tamron 150-600 first.  I also need a full frame wide angle lens then I will think about a new crop camera.

I wil rent a 7D II and a 70D before I make a decision.  I really miss the articulating display of the 60D every time I use my 6D. 

The 7D II looks like a real good camera.  I want to see the 7D II ISO performance and how it performs against a 70D. 

I would have liked to have see:
  • WiFi for remote control
  • Articulating screen
  • A change away from CF to CFast or XQD
  • 4K video

Not that I care for 4K video but I think Canon should stay current.  It always seems that Canon Cameras are released a year late to me.  I do not have CF cards and do not want to buy them for a camera when the next gen will likely replace them  with something faster.

 CF is nearly legacy we should prepare to move on to a serial bus.

EOS Bodies / Re: 6D and 7D II Combo or 5D III?
« on: September 18, 2014, 09:05:31 PM »
I deiced to go with the Combo and bought a 6D last year.  I have not been disappointed. 

I now use a 6D and a 60D.  One of the key factors for me was the Cost and lack of a fast SD reader on the 5D III.  I am not invested in Compact Flash so that would be an added expense for me.  I am heavily invested in SD cards. 

I came to the conclusion that most of the things I wanted the 5D III focus system for I would need a longer Lens than I can afford.  What I wanted a full frame camera for High ISO for did not need the 5D III focus system. 

Having a 60D I realized that the edge case of wildlife in low light shots can be done with the 6D focus system. 


You have a 7D so do not need to factor in the cost of CF cards.  The real question is the 5D III worth the price of a 6D + lens or 6D +7D to you.  For me it was not.

After I buy the Tamron 150-600 and the Canon 16-35f4, I will likely rent a 7D II and a 70D.  At that point I will have to make a discussion as to what my next camera will be.

Lenses / Re: Lenses that you want Canon to release next
« on: September 17, 2014, 09:52:28 PM »
I would like to see a new
  • 100-400L
  • 135 f2 IS L
  • 180L IS Macro
  • New 50mm

All of the Canon 50 mm need updating.  I included the dates for just how old those lens are. 
  • 50L is great but a real specialty has some focusing issues out of my price range anyway.
  • 50 1.4 USM (1992) needs fixing prone to breakage. 
  • 50 1.8 II (1990) is POS focus motor noisy slow, coatings suck, not sharp enough for my taste until stopped down to 2.8.
  • 50 macro (1987) is archaic.


Personalty I think they need to release a new 50mm F1.8 STM to keep it cheep and a new 50mm F1.4 IS L.
I would not mind seeing an updated 50mm Macro.

I may just buy the Sigma 50 ART tired of waiting.

EOS Bodies / Re: Canon EOS 7D Mark II Specifications Confirmed
« on: September 12, 2014, 06:10:54 PM »
I really do not know why they are arguing about DR stuff in a Canon EOS 7D Mark II Specifications Confirmed section.  There was no mention of DR in these specs.  I admit I am not really interested in DR arguments in a 7D II rumor thread.  Unless DR is specifically in the rumored spec. 

DR is important but is this the right place for this discussion.

But the Internet has its trolls.  Every rumor site has its trolls.  If you go to a Sony site you see a ton of complaints about not enough lens for A mount.  All the the rumors are about E mount.  The flash system sucks.  Followed by I am dumping all my gear if they do not release X lens and going to Canon.  Some then someone pipes up and states why not go to Nikon.  This is generally followed by a bunch of former Nikon customer with various maintenance nightmares.

EOS Bodies / Re: How does the reveal of the final 7D2 specs make you feel?
« on: September 12, 2014, 05:15:46 PM »
"Tourist Landscape Photographer" reporting for duty! Nothing wrong with a non-action simple full frame camera - 6D is perfectly fine for landscape and general photographers in the Canon camp. One can argue that the landscape photographers should consider Sony A7r (or whatever Sony next produces in a high-res body) with adapters, rather than the few-hundred-dollars-less 6D body. PJ, action, event photographers need something else. Focal-length-limited action high-end shooters need the 7D2, non-FL-limited action high-end shooters (events, weddings, etc) need the 1DX or 5D3.

I thought about buying the A7r but find the lack of an electronic first curtain is a deal breaker.  The A7r has to shut the shutter twice to take a picture.  This can cause visible camera shake at landscape shutter speeds.  The A7 has first curtain electric shutter but I want the higher MP.  So I bough a 6D.   I was not interested in the current Sony EF lenses.  I though it would be strange to spend that money on a camera then manual focus Canon and legacy glass all the time. 

I will buy the A7r if they add electronic first curtain shutter or a successor if it has electronic first curtain shutter.

Lenses / Re: What New Lens are You Most Excited About?
« on: September 12, 2014, 04:57:14 PM »
Guys, maybe it is a stupid question but I wanted to ask the following: If I put EF lenses on my crop camera (7D), I know that 24 mm lens will be equivalent of 38 mm. lens. However, if I put EF-S lenses of 24 mm, will I have 24 mm on crop camera or that will be 38 mm equivalent.

Once more time, sorry for such question but I really want to know the answer.

A 24mm lens is a 24mm lens regardless of crop factor.  So it will be 38mm equivalent.  The EF-S10-22 is 16-35 equivalent.

I am a little disappointed that this thread has dissolved into DR speculation.  But not entirely surprised.   

The 70D on sensor Phase Detection auto focus is market leading.  In fact it is Revolutionary.  it is ahead of Sony on sensor Phase Detection by at least a generation. 

The Sony Exmor sensor as better sensor read out.  They also apply some noise reduction in sensor before going to RAW file.

We do not know what dual DIGIC 6 brings to the table.  Likely lower readout noise and improved DR.  So how about we put a cork in it until we get real comparison.  Or at least go to one of the plethora of other threads that already discuss this.

If Canon puts in cleaner A/D converters there goes the Exmor advantage.

EOS Bodies - For Stills / Re: Do you need a really high ISO?
« on: September 12, 2014, 03:01:47 PM »
One thing that hasn't changed is that size matters.  The low-light CMOS sensor you linked is FF...the 7DII/X won't be.

The 'affordable body for low-light shooting' is called the 6D – you can buy one today at retailers everywhere!

Neuro hit the nail on the head if you want high ISO buy full frame. 

That said I really need usable ISO 3200 in a crop sensor for wildlife use.  I simply cannot afford the big whites for full frame use.  The 7D2 should be close for my purpose.  I will settle for ISO 1600 and 2/3 stop boost in post. 

Without radical change in sensor tech ISO 3200 usable on crop is probably the best we can expect.

  • Canon EF-S 24mm f/2.8 STM Pancake crop and already have EF-24mm f/2.8 IS so not really that interested.  If it was full frame that would be a different story
  • Canon EF 24-105mm f/3.5-5.6 IS STM soon to be cheep kit lens EF 28-135 soon to be discontinued.  (Does this mean the Rebel F is real?)
  • Canon EF 400mm f/4 DO IS II interesting but more than I can afford
  • Sigma 150-600mm f/5-6.3 DG OS HSM (C) not likely good enough
  • Sigma 150-600mm f/5-6.3 DG OS HSM (S) interested how does it compare to the Tamaron 150-600 I want.
  • Samyang 12mm f/2.8 Full Frame Fish Eye need 150-600 more than a specialty lens
  • Tamron SP 15-30mm f/2.8 Di VC USD most likely to buy the new canon 16-35f4
  • Zeiss Otus 85mm f/1.4 if I win the lottery I might consider this.

I still think that the 24-70f4L will soon replace the 24-105f4L as the L kit lens and the 24-105f4L will be discontinued when current supplies run out.   The EF 28-135 will be discontinued replaced by the 24-105 STM as a low cost entry level full frame kit lens.

Pure speculation but Canon could be preparing to release a full frame rebel as the world newest cheapest full frame camera. 

I really need to get a 150-600mm lens and a full frame wide angle but do not need f2.8 so the Canon 16-35f4L and a 150-600mm are top of the list.  I have found the max focal length of every Tamron lens I own is there weak point so I want to see a 600mm comparison between the Sigmas and the Tamron.  But a new Canon 100-400L could change my decisions if it is good enough.

I have moved on.

I now use full frame Canon / Sony Mirror-less for general photography needs.  So I am not really interested in DR when it comes to a 7D2.  I am in the market for a dedicated crop wildlife camera.  So my primary concerns are ISO 3200 performance and price.   I would prefer it to be 60D sized but I know I am in the minority with that. 

I could care less about touch screens but really miss the 60D adjustable display when using my 6D.   So I would like to have seen that feature. 

I have been waiting to see if it is a big enough jump over the existing 70D to justify the price difference.  Both the 70D and the 7D should meet my focusing needs.  I see the ISO specs a general marketing garbage for the most part.  I will wait for a review.  Then I will make the decision do I keep using my 60D or move to the 70D or 7D.   Or rent both to decide.

In my experience the ISO performance of the EOS M is better than the 60D.  I expect the ISO performance of the 7D II to be better than the 70D.

We currently have an incomplete list of specs.  So as usual I will withhold judgment until the camera is officially announced.  It looks like it will be a larger camera than I would like but if it gets me usable ISO 3200 in a crop camera I might be tempted. 

What I consider usable is completely subjective.   Until then I will wait for the images.

If you shoot raw, then stick with ISO100 and be prepared to "underexpose" then fix in post.


well that's not good advice! :D

Care to explain why shooting at ISO100 but underexposed by 2 stops is worse than shooting at ISO400 on a Nikon 800/600 series?

Numbers are useful here.

Try it.

This is how I shoot low light on my 30D..  I stop at ISO800..   here's the implied readout noise levels from the DxO data...  on the D800 looks like ISO200 is worth having but benefit rapidly drops beyond that.

that´s all fine, the data i mean.

but what if you only have 1024 tonal values you can boost because you underexposed so much.

from experience and not whitepapers i come to the conclusion that not underexposing by 2 stops and raising ISO instead i get the better images.

i usually shoot at a maximum of ISO 1600.

you may get a bit more noise but you also get more tonal values.
i can clean the noise in post but when i have banding it´s hard to fix that.

Personally I do not think that it is ever a good idea to underexpose by 2 stops on any camera.  Unless you using it for artistic effect.  So is it at that point underexposing? 

I generally prefer  to under on my Sony by at max 1.5 stops.   2 stops is pushing it a bit far.

It seems any time a discussion like this we fail to realize that Canon and Sony sensors are flat out different.  The techniques for maximizing their performance are different.  As is everyone's artistic expression.  Canon ETTR, Sony/Nikon ETTL, but regardless of what is best approach for the camera EXPOSE FOR THE SCENE. 

Last year I took a picture in the woods with my Nex6 in which I intentionally underexposed by 2 stops.  Then in Lightroom adjusted exposure slider up 1 stop, highlights up 1 stop, shadows down 1 stop, and drove the black slider nearly all the way to black.  The image was a little over saturated so I had to reduce saturation.  It produced the image I intended to take and I have done very similar shots with my 60D.

There are no hard rules but In general as you go up in ISO the closer you need to be to proper exposure to the scene.  The more DR in the scene the closer to proper exposure you need to be if you want the DR in the final picture.

The more DR the sensor has the more adjustment options exist in post at low ISO.  So for the Sony sensors there are cases where using lower ISO and underexposing to keep shutter speed up is appropriate.  The DR can be used to adjust in post.

Max ISO in general for me is the following. 
Nex6/EOS M ISO 1600 (800 no noise reduction)
60D ISO 800(400 no noise reduction)
6D ISO 3200

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.
