Canon EF Zoom Lenses / Re: Canon EF 24-105mm f/4L IS USM
« on: October 26, 2014, 04:44:43 PM »
The Keep of Scarborough Castle, northern England, shot from the barbican; that is a fortified, narrow entrance where should invaders manage to get through the gate way they would be herded into a highly vulnerable position before reaching the castle.  A three frame pano stitch, so the sensor size for this picture is actually slightly larger than that of an S2 or Pentax 645.

5DII + 24-105L @ 35mm, f11, 1/40 and ISO 100.

I really like this shot. Nicely done Sporgon.

Thanks Click ! I am pleased with this one.

A view of Scarborough South Bay and Oliver's Mount taken from the walls of Scarborough Castle, England. Scarborough is a very popular seaside resort in the north of England.

4DII + 24-105L @ 50mm, f8, 1/160. A five frame panoramic.


Great view and wonderful in panorama captured. The name Scarborough reminds me of Scarborough Fair (S&G)
New camera?  8)

Many thanks candyman. English Heritage have built a new stairway up to one of the ruined turrets on the walls of Scarborough Castle, so that enabled me to get the shot.

Yes 'Scarborough Fair' does refer to the annual fair that used to be held at Scarborough in the Middle Ages, when it was a 'Borough' of national importance, sited below the castle which dominated the area. Simon & Garfunkel made the traditional English ballad world famous.

4D - CR never saw that coming did they  ;D

I've amended it !

EOS Bodies - For Stills / Re: Pulling the trigger on a 6D
« on: October 25, 2014, 07:58:22 AM »
I have both and my rather random thoughts would as follows:

The 6D is a really good fit in hand, better than the 5D/5DII. Although only slightly smaller it is more 'handy'.

The AF seems to be more precise than the 5D/5DII on all points.

The 6D uses some kind of colour metering whereas the 5DII doesn't. Haven't made my mind up on this yet, it behaves differently to the 5DII in some situation ( bright blue).

The overall 'IQ' is remarkable. There is a subtle improvement in low ISO, very good, film like tonal graduation and greater latitude at both ends of the EVA range. High ISO is astonishing and way ahead of the 5DII from about ISO 800 onwards. Overall I would put the 6D up against an A7r any day, there is not as much practical difference between 20 mp and 36 mp on FF as you may think, and the whole DR range on the 6D is very useable, making real world differences academic most of the time.

The 6D has a polymer top plate which feels identical to the mag alloy top of the 5DII but does get scuffed and scratched more easily as it is relatively soft.

Now the bad bits, at least for me. It uses the 'second tier' userface and ergonomics. The controls work fine per se, but moving between each is annoying, at least for me. However as you have sold your 5DII you won't have this issue. The top command wheel is very softly click stopped, and the rear command wheel is, well to be polite, disappointing after the 5DII. Also the flash compensation has to be done via the main menu although you can assign it to quick menu and then it is quite useable to be fair. So to summarise I'd say it's not as 'positive' on the controls as the 5DII series, but you get used to it and then it works fine.

For canon, exposure for a 400mm 5.6 on a crop (640mm 5.6) is the SAME exposure as a 400mm 5.6 on a full frame. By using a crop sensor the aperture doesn't magically shrink. Just like taking the center section of a full frame image to give the same view as a crop sensor does not shrink the aperture.

Jarrod

That is because correct photographic exposure is dictated by the intensity of light, not volume. So you are of course right that the exposure for a given f stop lens will be ( more or less depending upon the efficiency of the lens) the same irrespective of sensor size or image circle, but when you begin talking about Achieving the same result on different formats you must deal with equivalence in all areas if you want to be correct - not just the 400 to 640 bit  ;)

Lovely picture Sporgon.

Many thanks Click ! The full panoramic sweeps across to the right taking in the castle walls and tower so I'll post that when finished.

On the subject of lens prices it is interesting to note that in the UK the 24-70 f4 IS retailed price is now cheaper than the 24-105L retailed price.

Technical Support / Re: Do I Need $ 634 US Dollars Light meter ?
« on: October 18, 2014, 04:07:08 PM »
Call me crazy, but if you are shooting digital, the need for an accurate meter is much less even in studio, because you can shoot, review, adjust, 10 times in 2 minutes. 
And you can probably pick up a used meter on ebay for $20-50 that will get you within a half stop of the high end meter you are looking at.
And last, even a super-duper high end meter is not going to give you a perfect exposure because we all have some personal taste in what we want to see. Are you shooting a scary Halloween scene, where you want it extra dark?  Toothpaste commercial, where it has to be extra brute etc? 

On the other hand is this the last piece of the puzzle in $100K studio where you intend to make a living or enjoy your retirement?  Is this going to provide the inspiration you need to shoot that piece of art that will hang in a gallery and earn a ton a $$?  Go for it.

You're crazy  ;)

I use an incident light meter a fair bit. Knowing where the 'correct' exposure is for a given lighting situation is really useful, at least for me. It also gives a clearer picture of where the histogram should sit in relation to the latitude of the camera.

EOS Bodies - For Stills / Re: So what makes a camera a "pro" camera?
« on: October 17, 2014, 06:01:43 PM »
Canon didn't fit the 5DIII with a stainless steel bottom plate for 'consumers' - honestly. It not even been used by a Canon as a marketing feature, it's there because the base of pro cameras tend to get hammered, and a nice touch by Canon. Stainless is also a lot harder ( pun intended) to form than the likes of mag alloy.

If you are used to having the IQ from the 70-200/2.8II I'm really surprised that you still have the 70-300 non-L. I've had the misfortune to try a couple of these, and although they were surprisingly good at 70 -100mm focal length, the rest was just dire, apart from the sort of spot meter size centre when stopped down to about f16.

The 70-300L, on the other hand is a really good lens, quite stunning in fact, pretty much as good as the 70-200/4 IS, just losing two thirds stop at 200, but gaining another 100 in reach.

Blue Jays and Peanuts - The Fall Fiesta


Every fall, the Blue Jays return. Noisy, obnoxious, and incredibly beautiful, these birds seem like they belong in the rainforests of Papua New Guinea with all their colorful friends. They are also incredibly intelligent birds, extremely clever in finding and rooting out food, and particularly sneaky bastards. ;) I've spent the last couple of years "training" the Blue Jays that frequent my yard. They come when I play back Blue Jay calls from my WP8 Sibley guide, come when I tap peanuts on my deck, and seem to enjoy the game of "Grab the peanut before a photograph is made!"


The Scrub Jays are a little easier to capture photos of, they are a little more aggressive with the Blue Jays, and tend to get all the peanuts. This year, I managed to lure in a couple Blues, and with some a clever setup, captured a number of wonderful shots. There is mere moments to frame, focus, and shoot before they are gone. The 5D III's slower frame rate makes getting the perfect moment a little more difficult, however it's larger frame makes for a much more pleasing background.

Here are some shots of the setup used to get these images:








While I was snapping shots of the setup, my quarry showed up again, and grabbed a little more bait. :D




Really nice shots, the pictures have a lovely quality to them  ;)

What I am saying is 'in same generation sensors the differences between a crop camera, and cropping a ff camera to get the same fov, especially appropriate in focal length limited situations, shows negligible difference in resolution even in ideal situations'. You can only test this with same (or very close) generation sensors, 6D and 7D MkII would be valid, 5D MkII and 7D would be valid, etc etc, if you don't have two same generation sensors you cannot test this and any 'illustrations' are entirely bogus, as all yours have been when we have danced this dance previously.

Baloney.  I specifically went out and proved you wrong by shooting intentionally at highly non-ideal settings, and still the difference is quite substantial.  Here it is again.  The differences are much larger using ideal settings.



Lee, I think another area you are going wrong with this comparison is that the 5D requires a fair amount of careful sharpening, whereas ( if I remember rightly back to 2004), the 20D did not. Bear in mind that back in the day those two cameras were aimed at different typical users. If you tried to optimise the 5D first I don't think there would be such a difference, and as the other guys have said, they are referring to current, or current-but-one generations cameras.

What your test shows is that the later generation is better. No surprise there.

EOS Bodies / Re: Patent: Variable Diffusion Focusing Screen
« on: October 16, 2014, 09:14:42 AM »
In spite of the naysayers, this will be a very useful technology for anyone shooting with a mix of fast primes and slower lenses, and innovative of Canon to work toward a dSLR implementation of the technology.

Yes, photographers like me. I use fast primes but slow ( 24 to 300 range ) zooms, principally because I don't want to weigh myself down with heavy zoom lenses. The different screen characteristics required are a nuisance. It would be pleasing to have both in one.

My only concern is that is is going to be done with activating LCD, which in itself may not give the crisp clear screen view of current S screens when in focus.
