Lenses / Very Stuck Filter
« on: May 31, 2013, 05:50:34 AM »
Hi All,
I dropped a 70-200MM F2.8 II a pretty heavy lens head first onto a wooden floor.
There wasn't much damage, the lens itself seems to be functioning pretty well.
The UV filter however is dented and rigidly stuck in place.
I've tried all the normal methods of filter removal.
ie: Rubber Band, A Lens Filter Wrench (which I especially bought to remove it - These weren't great. They don't grip that much, with the filter there isn't that much to grip anyway), by hand, shoving it into a rubber mat and twisting etc.
I even put it in a freezer to see if that made any difference.
I had settled on just leaving it there stuck, the glass in the filter is fine.
My problem is I can't attach my 10 stop filter to it - and I'd like to be able to do that.


Anyone got a good idea about what to try next?
I've seen a Youtube demonstration of scoring the glass tapping it and removing it and then hacksawing the filter to weaken it and then removing it. This seems fraught with danger to the lens.

I can't be the first person this happened too. I am hoping somebody has a winning suggestion.
The filter is a Hoya so I assume it's aluminum (but not sure).
I was told if it was brass I might have had some chance.

Your in hope

Speedlites, Printers, Accessories / Ring Flash for Macro Work
« on: April 20, 2013, 06:55:30 PM »
Hi All,
I was wondering if people had advice as to what Ring Flash I should by to help with Macro work.
I find it hard to find a comparative study of Ring Flashes .
I'm open to any brand.
Look forward to your knowledgeable input.
Kind Regards

Lenses / Jammed Filter
« on: April 13, 2013, 11:57:56 AM »
Hi all
I unfortunately dropped a lense or of my bag today onto the floor.
Unfortunately it was a bad choice.
It was a 70-200mm is II so it was a Big Bang. The lens looks intact but the UV filter is jammed and dented.
I've tried using a washing up glove to get grip and putting it in a freezer.
It didn't budge a millimetre .
Anyone got a suggest as to what to try next
Kind Regards

Lenses / Focusing Advice on a Canon 24mm TS-E
« on: April 09, 2013, 10:15:25 AM »
Hi All,
I have a new Canon 24mm TS-E II and am still only getting used to it.
I have a few Samyang Manual Lens (8mm and 14mm) and you get away alot with manual focussing because of the wide angle. It tends to be hard to be too far out of focus.
If it looks in focus in the view finder it's pretty much in focus in reality.

With the Canon 24mm TS-E it's a little trickier.
I am using a Canon 5D Mark III
Unshifted/Untilted it's not so hard to focus and it's pretty sharp.
As you tilt you start getting out of focus and then it getting tricky to focus the parts you want to be in focus.
So generally I use live view but I'm not sure whether there is a better method or more precise way.
Specifically I've seen that people use a Hoodman Loupe sometimes to view the screen.
I am wondering would using one of these allow you to focus more accurately than using 10x on the screen.
If you used the Loupe with the screen at 10x is it all pixelated or the most accurate way to judge accuracy.

I'd also be interested if anyone had links to instructional videos or websites on using the Canon TS-E.
I am interested in finding out roughly the degree of tilt required for the  Scheimpflug principle.
From my experimenting it appears to be very little as it starts to blur very quickly as you tilt down (which I believe is the direction of tilt required for the Scheimpflug principle.
The other thing is to learn the degree of shift required to straighten up buildings. This is trickier than I thought it would be. Focusing keeps changing and blur is introduced as you adjust.

It's a very interesting and enjoyable lens I must say. You can do alot of the effects in CS6 pretty easily nowadays. It's nice to do it without that and it slows down your photography alot as there is alot to concentrate on. It helps improve composition and slows down the number of shots taken.

I have taken a few shots I'm happy with and have them up on Flickr. They are not amazing by any means but crafted only using the lens and little or no adjustment in Photoshop (which is a change for me)

Third Party Manufacturers / Samyang 24mm TS-E
« on: March 01, 2013, 04:00:09 AM »
Hi All,
Seeing as it's the first of March and the Samyang UK facebook site said it would launch it in March 2013:
Has anyone seen any update on that or any prerelease preview?
I have two Samyang Lens and I'm pretty happy with them
Do people expect Samyang could produce a good TS-E Lens?
I've never seen a Sigma or Tamron or Tokina TS-E. Maybe that's because they are a specialised and not mass market object.

Lenses / Tilt Shift Lenses - Looking for Advice
« on: February 21, 2013, 04:03:38 AM »
Hi All,
I'm really tempted to save all my money and buy a Canon TS-E 24mm II tilt shift lens.
Alot of people like the 17mm version and there is a 45mm and 90mm version.
I had a few questions.
a) Is 24mm more useful than 17mm or would the use of an extender actually make 17mm more useful
b) What would you use a 45mm TS-E for - is it designed with a particular type of photograph in mind
c) What would you use a 90mm TS-E for - A few of the minature videos or photographs I've seen have been done with this focal length but I assume thats not the real purpose of that focal length

What would I be using if for - I love sharpness I would like to achieve back to front sharpness for landscapes.
I might do a bit of architectural photography.
I do like the tilt (minature) effect (although its got quite common and the examples are getting worse).
If you use an extender with a 17mm is it then a bit restrictive as the maximum aperture is reduced?

I'd be interested in any advice.
The 24mm TSE would be my favourite at the moment.
I have a 50mm Flektogon Pentagon 6 on a Arax tilt mechanism.
It only tilts - it's like a hard to control Lensbaby.
I'd love a real tilt/shift lens.
I'd be interested too in those who have a tilt shift lens.
They are so expensive - do you actually use it alot afterwards.
It's a bit like a holy grail object.
I was like that with the 70-200 IS II - it even exceeded my expectation and I'm delighted I saved up for it.
Will I have the same sort of moment with a tilt shift lens.

EOS Bodies - For Stills / Better Dynamic Range in a Camera
« on: February 18, 2013, 06:12:21 AM »
I own a Canon 5D Mark III which is a great camera. I still have my 500D which is still a very good camera which I still enjoy using. The 5D has better ISO and Focusing and lots more buttons. It has a bigger sensor which does help improve image quality and does nice things with depth of field. The ISO improvement is really great.
One thing that maybe is better (but not obviously better) is the dynamic range of the sensor.
I can't see a whole lot of improvement over a 500D (I may not be looking properly).
What would be a great leap forward would be a sensor that captures the light in a scene with all it's ranges like an eye would.
I've seen in places that some people think the human eye has a dynamic range of around 20 stops other saying 6.5.
I've also seen it said that the dynamic range of a camera (9-11) exceeds the dynamic range of print (6.5 stops).

I am not a techical expert in this area and I know the eye is quite a complex mechanism and the brain also tinkers with an image but:
When I look at a scene with alot of different light I can take it all in and I see a picture in my mind.
When I take a photograph of it certain areas are lighter or darker than I saw.
I then have to edit my image to something approximately to what I saw (or thought I saw).

How hard is it to make a sensor with a higher dynamic range?
Can it be translated into something you see straight off on a screen or a print?

I'm sure a company that could produce a camera that produces images more like how a human sees the scene as would really be onto a big winner.
What would it take to do that?
Is it better dynamic range ability or is it something else that's required?

Kind Regards

Video & Movie / My First Video - Short and Sweet
« on: December 11, 2012, 06:28:30 PM »
This is my first attempt of video on the Canon 5D Mark III.
Alot of room for improvement but I've been inspired by some of the people here to give it a go.

Abstract / Abstract Interiors
« on: December 11, 2012, 04:23:54 PM »
I was looking for a spot to place this so I created a new subject called Abstract Interiors.
This is the inside of a Hotel in Cork City Ireland shot with a Fisheye Lens.
It reminded me of something out of a Stanley Kubrick movie.

Would love to get some comments or some other abstract interiors.

PowerShot / Glass Scratch on G12
« on: May 09, 2012, 11:20:22 AM »
Hi All,
I love my G12 I use it as a backup camera. I often squeeze it into my pocket.
Unfortuntately it doesn't have a Lenscap (which I think the G1X now has).
At some point it must have rubbed against keys.
The lens is slightly scratched :'(.
Is there anything can be done with that - can you buy anything that reduces scratches (without reducing image quality)?
Would that be an expensive repair :o?
Kind Regards
Hector

EOS Bodies / 5D Mark III is it better than the 5D Mark II
« on: April 18, 2012, 11:14:15 AM »
Hi All,
Since the 5D Mark III came out there seems to be alot of people on this forum disappointed about it. Some say that Canon didn't listen to the users. Others are saying the Nikon D800 beats it on all specs.
I like alot of people who come here probably have invested a fair deal in Canon compatible lens and so at least for the moment are fairly stuck with Canon. It would be a major chance to move to Nikon at this stage and a major sell off of existing gear.  :-\
What I am wondering is are there people here with real world experience (as opposed to Spec knowledge) of the 5D Mark III and how does it compare to the 5D Mark II?
Is it a major improvement on the Mark II? ???
Kind Regards
Hector.
