EOS Bodies - For Stills / Why not 16 bit files?
« on: February 15, 2015, 01:22:56 PM »
I do not claim to be as technically savvy , but the question hounds me, why does Canon not start using 16 bit files rather than 14 bit, why this 14 bit brickwall? Color depth, DR can certainly benefit from doing this. I accept that there will be an increase in file size, but many would happily take that if it gave them more latitude or IQ.

Can someone tell me what I am missing?

(Apologies, I came out of the 80's CD redbook thinking, where 16 bits were not enough, then came 18 bit converters, then 20... and finally we were happy at 24bit before DSD ruined the party...... There seems to be a reluctance in upping the Ante in Digital photography).

I believe Canon's banding has to do with the algorithms they use, its not a hardware issue. Granted there is some noise at the hardware level, but the banding is a software issue or so it seems.... an optimized algorithm would produce more uniform/ random grain that is not as ugly as vertical/ horizontally focused bands...

Is LR5 even available as a standalone anymore?

Third Party Manufacturers / Features on the iphone 6+
« on: September 11, 2014, 12:26:05 AM »
Nice to see cross pollination of technologies by different manufacturers:

The iphone 6+ has:

BSI sensor
Optical Stabilization
Phase detect AF on sensor
1080p 120 and 240fps !

Helps the consumer with choices, and pressures all manufacturers to up their game (just as Samsung is lighting a fire behind Apple :-) )

EOS Bodies / How do reds come out in your 5d3 ?
« on: August 13, 2014, 12:29:07 AM »
I have often struggled with red objects in my 5d3. I wrote last year about it but did not get any replies. Yesterday while trying out my new 85 1.2 ii, I saw the same issue.

Red flowers come out in an over saturated red haze. The other colors seem saturated just fine, but the reds are over powered so much that the flowers lose detail.

I can reduced saturation in LR, but then the whole image looks washed out... the issue is only with reds.

If I reduce just red (Red channel only) , then it lacks punch, although I get back details in the flower...

Has anyone else observed this?

I didn't find a thread for this unloved lens, so I started one: All shots downloaded form facebook since I don't have access to originals right now, so they were heavily compressed....

Lenses / Anyone use Swarovski spotters for Bird shots?
« on: October 01, 2013, 04:20:11 AM »

A Guy I work with is into Bird Photography. Since we are all challenged by distances, he mentioned that if I was willing to go manual, that this might be an option:

It might be a bit pricey, but if it can do decent 1700mm equivalent shots, might be worth the price.

Anyone used this sort of non-standard set-up? What are the results like.

I had a Manfrotto 055PROB which I loved except for it's weight... it was too heavy to strap to a back pack and hike around. Now I am

I would like something between 2-3lbs
Can collapse to 6 " from ground for macro (no 12" center columns)
Can support 10lbs (My biggest lens is the 70-200 mk.II)

Some nice to haves would be small folded footprint (prefer 12-15")
Ability to convert into a monopod, but not at the expense of 2 requirements above.

Price range : up to $400

What would you guys get?

Lenses / What price to pay for a used 500mm F4?
« on: October 18, 2012, 02:53:40 PM »
Is the version 1 sharp? What should I pay, one has showed up in a local CL for $2500 with the casing.


Lenses / AFMA'ed the 24-70 mk.ii ... not sure I am loving this copy.
« on: October 14, 2012, 01:59:42 PM »
I just AFMA'ed my 24-70ii the third time (i.e. Each time fine tuning both tele and Wide till I nailed both). +5 on the Wide and +6 on Tele with my 5d3.

The Issue I have is, the sharpness at 24mm has a lot to be desired... 70mm is fine I guess, but I had higher hopes for a $2300 lens... is this it or do i have a dud on my hands?

Pls see 100% crops of 24mm and 70mm below and let me know what you think... if all seems ok, I can send shots of the corners which are even more disappointing...

EDIT: Added MF shot
Third shot is MF @ 24mm

My Camera Shop called me and 30 days after I put in a Pre-order, I got my 24-70L ii  :)

My first shot was to compare sharpness with my 70-200 mk.ii. While the 70-200 does seem sharper (it's been AFMA's but not the 24-70 so I can let that slide... however with a test shot with both at 70mm, I was not prepared with the difference in framing... it is more than noticably different... I realize that there is some variation in difference lens models but I always thought 70mm should give me a similar framing regardless of the lens I used within a small tolerance... but this to me is huge. Is this to be expeced?

Attached are the shots at 70mm form the 24-70 ii and the 70-200 ii

Software & Accessories / Poll: What NR do you use
« on: October 09, 2012, 12:37:00 PM »
Just wondering what NR people prefer to use. I have CS5 but I like Nik Denoise in paralell with Topaz Denoise. I used to use LR NR and before that CS NR, but not anymore.  What do you guys prefer and why?

Votes are changeable:

Let me know if there are other software you guys use. I can add as an option.

Lastly: The focus of this poll is to get opinions from people who have used multiple products and have them share their reasons for preferring one over the other.

EOS Bodies / Pls Advise on testing a 7D on CL
« on: August 17, 2012, 04:12:50 PM »
There's a local seller who is selling a 7D with kit lens 28-135mm. He has no papaer work/ no box etc, just the strap / 1 CF card and lens covers. He says it is pristine condition and 2 years old. He is asking $1100.

How much should I offer and what should I test it for if the deal goes through..

Lenses / 85mm f/1.2 ii or 135mm f/2
« on: August 14, 2012, 01:19:35 PM »
Sorry if this topic has been covered before  ;) , but If I were to add a nice portrait lens to my collection of zooms, which one should I consider and why? Some of the things I would like you guys to factor in are:

Buying used, resale value, is the 85mm worth 2x the price of a 135mm etc


Lenses / What lens(es) should I consider for next purchase?
« on: July 30, 2012, 11:31:32 AM »
I know it depends on what kind of photography I do... but I am open to and like to explore new areas. I just sold my 100-400L since it did not give me a whole lot more reach/ sharp images as can my 70-200mk.ii with a 2x mk.iii, I would like some reach but the good lenses are very pricey. I like Macro/General people pics/citi scapes/landscapes etc.

I already have the 17-40, 70-200, 50 1.8 mk.ii, 180L. I got the 17-40 after selling a good copy 24-105L, while I like the extra width, I feel the corners are so mushy and distortion very noticable at the corners that I do not use that extra width... should I wait for the 24-70mk.ii or get the 16-35mk.ii ? I love the 70-200. I use it the most.

My budget is about $3500.  I am a hobbyist, and would probably re-sell the lenses after I get bored with them since I do not make money off the hobby...

Are there new avenues / lenses I should explore? What would you guys do?

Software & Accessories / Lens correction profiles for Canon on CS5
« on: July 08, 2012, 01:29:28 PM »

I just installed Photoshop CS5 and went to the lens correction filter. In order to auto correct, on has to choose the Camera maker and then the lens model... however in my case, I find 6-7 Camera makers listed but no Canon. I mean Nikon is there, Samsung is there, even Apple.... but no Canon!!  When I search using the online search button, nothing comes up. How can I get lens profiles for CS5 for my 5diii ?
