EOS-M / FD lenses
« on: February 07, 2014, 10:55:49 AM »
I was wondering if there are any affordable but 'outstanding', 'good' or simply 'fun' FD(n) or FL lenses that you would recommend to use on a mirrorless camera like the EOS-M or Sony NEX that I own.

I have an FD adapter and tried the FDn 70-210mm f/4 on my NEX but the lens's performance was poor with lots of purple fringing. I sold it and now bought a Canon FD 200mm f/4 S.S.C.  that I have better hopes for.

Other old stuff I own:

Vivitar C/FD 28mm f/2.8 Auto Wide Angle
FDn 28mm f/2.8
FL50mm f/1.8 II
FDn 50mm f/1.8
FL 135mm f/2.5 (haven't tried this yet but should be fun)

What's your experience with adapted FD lenses?

Lenses / Strange Lens Flare (Sigma 35mm + MRC filter)
« on: January 02, 2014, 01:38:35 AM »
FWIW I noticed the Sigma (with a B+W MRC filter on it) is sometimes prone to flare from off-scene light sources, as shown in these pictures. The fact that the flares are all on the right hand side is a coincidence, but all the flares are confirmed to be from bright street lights just outside the frame. I haven't seen any occurrence of the lens flare in horizontal position.

These shots were all taken hand held, with (near) open aperture (<f/2.5) and the lens hood is on. The camera is gripped but obviously the lens extends beyond the grip. I'm not sure that I like this effect, and it is something I may want to avoid in the future but on the positive side it does have something reminiscent of the anamorphic lens(flare) effect as seen in some movies.
Does anyone recognize this flare, is it something to do with the MRC filter? All of my UV/clear filters are B+W but this is probably the ony one I have with a multi reflective coating (MRC). Cheers.

EOS Bodies - For Stills / 5DMkIII AF performance at f/8
« on: December 18, 2013, 02:50:21 PM »
I'm wondering about the AF performance of this body at f/8, specifically using the Canon EF 100-400mm L IS USM +  1.4x Extender II (=140-560 f/6.3-8).

I've never used an extender with my 100-400 before, but because I'll be losing the crop factor of the 7D, I am a little concerned re the impact on AF and image quality for those times I need the extended reach.

Anybody care to comment? Cheers.

PowerShot / IXUS fun
« on: November 23, 2013, 02:05:12 PM »
I bought a new IXUS 132 (Canon ELPH 115 / IXUS 132 / IXY 90F) yesterday for only 69 Euro's and decided to try it out on my cat. Here's a few shots; I had a lot of fun! ...and it's interesting to try out some of the digital filters. It's a great little camera. The only thing that's really missing is a 'shutter priority' mode (there's only 'P' and all the creative stuff). So to get fast(ish) shutter speeds the only workaround I could think of is to increase the iso. All in all I'm very pleased with the results. Not bad for such an affordable little camera. The build is good, too.

Has anybody noticed the charger gets hotter if 'recharge performance' gets worse? I just noticed my charger was running fairly hot. The battery charging in it is at one (red) bar. Discharge performance of the battery is still good though.

Lighting / Using (Fill) Flash
« on: August 03, 2013, 07:24:44 AM »
So I've been doing most if not all of my photography over the last 7 years without using a flash. I like ambient light and hate what an external flash does to the weight balance of my camera body.

I'm pretty happy with most of the results but it's time to get more out of my photography and start using fill-flash. The goal however is to preserve as much ambient light as possible; I dislike it when a flash has obviously been used to get a picture.

So my question is: Do you have any recommendations I can start out with? What conditions would typically require which settings?

Note that I would like to use it for general photography because I do very little portraiture.

FWIW I have a Metz 48 AF-1 with a STO-FEN Omni Bounce. I'm not immediately interested in getting more flash gear or reflective screens etc.

Thanks all!

Lenses / What's your oldest Canon EF lens?
« on: July 20, 2013, 06:00:00 AM »
I'll kick off with my Canon 28-70 f3.5-4.5 II  :)

Datecode UC0500: Utsonomiya, 05/1988

I've also got the original hood (not shown).

Canon Lens Date Codes - How Old Is That Lens?

Beside the rear lens element of many (but not all) Canon lenses is a date code (as seen above) in the form of "UR0902". This code is also present on many other Canon products including camera bodies.
 
 The first letter, "U", indicates that the lens was made in Canon's Utsunomiya, Japan factory. Prior to 1986, this letter is moved to the last position of the date code.
 
 U = Utsunomiya, Japan
 F = Fukushima, Japan
 O = Oita, Japan
 
 The second letter, "R", is a year code that indicates the year of manufacture. Canon increments this letter each year starting with A in 1986 and prior to that, A in 1960 without the leading factory code. Here is a table to make things simple:
 
 A = 1986, 1960
 B = 1987, 1961
 C = 1988, 1962
 D = 1989, 1963
 E = 1990, 1964
 F = 1991, 1965
 G = 1992, 1966
 H = 1993, 1967
 I = 1994, 1968
 J = 1995, 1969
 K = 1996, 1970
 L = 1997, 1971
 M = 1998, 1972
 N = 1999, 1973
 O = 2000, 1974
 P = 2001, 1975
 Q = 2002, 1976
 R = 2003, 1977
 S = 2004, 1978
 T = 2005, 1979
 U = 2006, 1980
 V = 2007, 1981
 W = 2008, 1982
 X = 2009, 1983
 Y = 2010, 1984
 Z = 2011, 1985
 
 * assumption of continuation being made for future years.
 
 The first two numbers, "09", is the month number the lens was manufactured in. Month 02 is February, month 11 = November. The leading zero of the month code is sometimes omitted.
 
 The next two numbers, "02", are meaningless in determining how old a Canon lens is. This is a Canon internal code (that is occasionally omitted).

Lenses / Move from 24-70 f/2.8L Mk I to 35mm F/1.4?
« on: July 18, 2013, 08:04:09 AM »
I'm considering selling my 24-70 f/2.8L MkI because it has gone practically unused since I got the 24-105 F/4L IS.

Now I'm considering getting a 35mm f/1.4 instead - either the Sigma or the Canon. At the moment I think I would prefer the Canon eventhough I've good experience with my Sigma 50 mm f/1.4.

I know these 35mm lenses have been discussed to death but now that for most people the initial love affair with the Sigma is probably over, I'd like to hear your *real world* thoughts on the matter of choosing between these two. Maybe you've had to make this choice yourself or even owned both lenses.

I know about the lab test data but prefer to hear from you some real world comparisons. These include portability, reliability, subjective quality etc etc. So please, your (subjective) opinions.

Currently I've a 100-400mm f/4.5-5.6 L IS and a 70-200mm f/2.8 L IS II +1.4 TC II in my kit. Both of these cover the (near) 300 mm focal length reasonably well, but...

I'm wondering if a 300mm f/4 L IS would be a useful tool to add to my lens line-up.

The objective is motion-stopping speed for animal photography (mostly in the zoo) and that 3D 'pop' that seems to be lacking from my 100-400 most of the times. 

What are your experiences with these lenses ie would it make sense for me to get the 300 mm prime?

Third Party Manufacturers / Digital Film (for use in old camera's)
« on: April 01, 2013, 04:08:40 AM »
I received some information that a large Japanese camera manufacturer is working on a digital film (that's right, film) that can be used in traditional analogue camera equipment.

The film uses a new type of binary image sensor technology that allows images to be captured and stored on the film without the need for electrical power to retain the data. Until now, imaging sensor technology has been limited to the use of volatile memory, necessitating the use of traditional CMOS or CCD imaging sensors and storage of the captured data on internal flash drives.

Binary image sensor technology is reminiscent of traditional photographic film. Each pixel in the sensor has a binary response, giving only a one-bit quantized measurement of the local light intensity. The response function of the image sensor is non-linear and similar to a logarithmic function, which makes the sensor suitable for high dynamic range imaging.

After exposure, the film is advanced in the same way as traditional analogue film.

When the digital film has been fully exposed, the roll is removed from the camera and connected to a computer or smartphone using a USB interface. Each stored image is read out successively and sent to the computer. The film can then be 'formatted' for re-use.

One roll can hold up to 24 images, but with advances in digital film technology it is expected that  higher storage capacities will become available when the film can be made thinner and wrapped more tightly.

Lenses / Canon EF 35mm f/2.0
« on: March 30, 2013, 11:42:46 AM »
Now that the Canon EF 35mm f/2.0 is officially discontinued but still available new at reasonable prices, I'm tempted to get one of these small primes before they become unavailable. The question however is if it's worth it.

I previously had one that I purchased second hand. It was on old, tired lens from 1990 or so and the performance was not what I expected from it, especially when compared to my fantastic 50 mm f/1.8 Mk I. So thinking it was a dud, I sold it on.

What's your experience with recent copies of the 35 mm f/2?  And how should they compare to the 50 mm f/1.8 Mk I? Intended use is on full frame as well as crop.

So, I now have a Sony Nex with a 16-50mm zoom and a 30mm f/2.8 prime as a small-size quality alternative to the 5DMkII and 7D. With an FD adapter I can mount (amongst other old Canon lenses) a Canon 70-210mm F/4.

Left in my collection of kit is a 400D body (with firmware hack: http://code.google.com/p/400plus/) and a very new EF-S 18-55mm f/3.5-5.6 IS II, and EF-S 55-250mm f/4-5.6 IS II.

I cannot really make up my mind on what to do with this kit I've sitting around - sell it or keep it? Not sure If I will find a need to use it again. I guess the 400D is not worth much money these days, and selling the two lenses I mentioned means a loss so I'm not comfortable with that.

What would you do? Keep this stuff around or get rid of it?

13
I've recently acquired a Sony NEX-6 because I wanted to get a good (APS-C) compact system camera and Canon isn't quite there, yet. The last few years I've been pretty loyal to Canon, until now.

What other camera brand do you actively use, other than Canon? If you like, please specify which model and why.

Lenses / No AF: Broken flexfoil in 18-55mm f/3.5-5.6 IS
« on: August 04, 2012, 02:04:24 AM »
Yesterday the AF on my 18-55 IS MkI suddenly became erratic and then stopped working. A quick search on the net shows this to be a common problem because the flexfoil that gives the focus ring position eventually breaks due to poor design. Disassembly showed this indeed to be the case on my copy.

I would like to replace the 18-55 with a Mk II version. Filter & hood I can then fit on the new one. Does anybody know if Canon fixed this problem in the new release of this lens?

Note: The 18-55 I use with my 400D when I want to travel with a light & 'expendable' kit. Not really inclined to use a more expensive lens for this purpose :)
