Lenses / Re: Patent: EF-S 15-300mm & EF 28-550mm Optical Formulas

We don't need superzoom lenses. Something that is good for everything is good for nothing. We buy DSLRs with interchangeable lenses because the Image Quality of a special purpose lens (10-24, 24-70, 70-200) is far better than an all purpose one (10-200 or whatever).

If you substitute "I" for "we" that's perfectly fine. But as written, your statements are ridiculous and manifestly wrong.

Photography Technique / Re: The joy of proper white balance.
« Last post by Mt Spokane Photography on November 20, 2017, 07:38:32 PM »
In low light, the camera is merely showing the scene as it is.  Our brains adjust colors and white balance to our expectations.  Thats why its so difficult to get a camera to automatically show colors as you see them.

In low light situations, there tends to be a definite lack of blue light.  It so happens that sensors are weakest in blue sensitivity.  This double whammy can end up showing a huge amount of noise if you turn up the gain of the blues to attempt to create a white light simulation.

I usually tend to prefer keeping colors as they actually are.

If you need the superzoom feature buy a point and shoot camera with superzoom (and manual control) capabilities like some of the PowerShot SX or G series.

While Canon does sell lenses to enthusiasts, there is a huge market for superzoom lenses.  Camera manufacturers make what sells.

Don't suppose we'll get deals anywhere  as good as this in the UK :(

I wish, the best deal I can find anywhere in the UK is £2997 ($3958) body only from Mifsuds

http://mifsuds.com/index.php?route=product/product&product_id=11242

If nothing better turns up i'm tempted to go for this deal (it's still way cheaper even without the US rebate and import tax) or a grey market import from Digital Rev's (£2119) body only.

https://store.digitalrev.com/product/canon-eos-5d-mark-iv/MTEwNDkwOA_A_A

Also on the grey side £2015 - https://www.e-infin.com/uk/item/3071/canon_eos_5d_mark_iv_dslr_camera_(body_only)
£2199 - https://www.hdewcameras.co.uk/canon-eos-5d-mark-iv-body-5161-p.asp

The process is different, as you are finding out, you need to understand the details and ignore the hype.  Thats true for any software.

I'd recommend downloading the trial and going thru the training.  There are promises of fixes for missing features, Don't bank on them.

Lenses / Re: Patent: Canon EF-M 15-45mm f/1.8-3.5

Since I know that Canon is waiting for my input, let me just say, YES PLEASE!

It would definitely push me over the fence to get the M5, but I am less than a squeak, certainly not even a voice, in the thinking of Canon product development. Oh well...

In another thread about EF-M lenses, I defiantly stated that I would not purchase another M product until Canon started to release quicker primes and zooms for the system. Then the Halloween refurb special came and a $637 M5 pushed me over the fence like a Friday night drunk. So much for resolve...

Reviews / Re: TDP reviews the 85 f/1.4L IS USM
« Last post by YuengLinger on November 20, 2017, 06:17:23 PM »
Got mine today, and as I posted in another thread, first thing I tried was to shoot metal in harsh light and the amount of purple fringing is extremely low, the 35 L II has none, and it’s there with the 85 IS, but even deliberately pushed to show it, it’s nothing to worry about.

Vignetting is very low, I was hoping for really good performance there, and I’m not disappointed.

The AF is very certain and locks and tracks great. Still in the process of finding the afma value, really impressive, even in terrible light.

I usually have very shaky hands so I had no hope for getting sharp images at the mentioned 1/8s, but I can get almost every single shot sharp at 1/8s. Ai servo locks without doubt, although slower in f1.4s, iso 1000 1/8s, pretty crazy.

Slight pincushion distortion but not noticeable  unless aligning up a straight doorframe in at the extreme edge.

Encouraging.

Third Party Manufacturers / Re: PhotoZone casts more doubt on 14mm f/1.8 Art AF
« Last post by YuengLinger on November 20, 2017, 06:15:31 PM »
for low light events shooting with such a wide lens and wide open, what you do is you prefocus to a certain distance, say at 2.6 meters ( 8.5 feet, whatever) this gives at 14mm and F1.8 a very generous depth of field being: 1.5 meters to 8.8 meters. Plenty enough! Set the lens to MF. AF accuracy aside, it takes longer for AF to kick in when it is really dark. that is how we shoot the dance floor. I hope it makes sense.

in addition, such a wide lenses are always AF inaccurate due to AF point covers larger area of the setting. Canon AF point size is roughly 2-3 percent of the viewfinder last time I checked. 14mm lens FOV is approx. 114 degrees diagonally. so that is a massive 2-3 degree. what the lens will focus on remains to be seen. Spot-AF should be more appropriate in this case to use but known to struggle in low light and in AI Servo mode.

Could you be any more hypothetical?  Two reputable reviews--at least--point out the AF is not reliable.  Sigma at bat!

I really doubt some of the Photozone results with the 5DsR.  I have an extremely hard time believing that lenses are resolving less information out in the corners on the 5DsR than on the 5D3.  Something doesn't seem right with their testing methodology.
