EOS Bodies - For Stills / Back Button Focussing and AF Points
« on: April 16, 2014, 06:31:35 AM »
I just attended a Canon Roadshow over the weekend where one of the speakers was extolling the virtues of Back Button Focussing (BBF).

The presenter explained about using BBF to gain sharpness on your subject and then recomposing your frame before engaging the shutter. It seems so logical and more precise to me!

His presentation finally made me 'get' BBF and I've decided to convert. Well, once the muscle memory kicks in

EOS Bodies / Evolution or the murder of art?
« on: March 18, 2014, 03:28:00 PM »
Disclaimer: This post is totally and utterly speculation and not based on actual developer announcements.

If the burst/frame count of cameras one day reaches and potentially exceeds 24 frames per second and photography possibly becomes an exercise of selecting frames from what is essentially a video reel, how would YOU, as a photographic artist feel about that?

I have a feeling that this advancement may initially raise it's head in camera phones for some strange reason.

Quite interested to hear opinions on this

EOS Bodies / Full Frame Vs Crop Sensor
« on: February 19, 2014, 05:21:58 AM »
Hi everybody  :)

So as I move into my 3rd year of photography, I find my 500D isn't able to help my take my photography to the next level and its beginning to feel like my L series lenses are begging to shoot on a full frame body.

I've never had the chance to shoot full frame so most of what I know is pure theory derived from reading reviews etc online.

With South Africa's economy in a bit of trouble, I can get a hardly used 5D mkii for a reasonable price so I'm considering taking that.

Just what can I expect in terms of image quality and noise performance? Is the IQ of a full frame substantially better than a crops? Will I be able to take relatively noise free images at say ISO 3200?

The reviews seem to indicate that the native system for L series glass is full frame. Does this mean that I will experience a dramatic improvement in IQ?

The more I read, it seems that crop bodies have a singular advantage over full frame and that is the increase in focal length.

Can you guys chip in and throw some opinions and facts my way please?

Thanks in advance everybody.

Lenses / 16-35/FF or 10-22/APSC
« on: November 17, 2013, 03:49:29 AM »
I've read a good few reviews stating the high quality of the EF-S 10-22mm and these reviews generally include a direct comparison to the EF 16-35mm II.

Sure, the edge definitely goes to the 16-35 but by the smallest margins.

Since the D800 launched a few years back, it has become apparent that shooting landscapes has more to do with lens/body combinations than just the qualities of the lens.

So my question; head-to-head, some reviews say the 16-35 is marginally superior to the 10-22 but I'd like to know how much better a 5D mkIII mounted 16-35 compares to say a 70D mounted 10-22 for landscape photography.

Thanks for any feedback folks :)

Lenses / Canon 400mm f/5.6 focussing issues
« on: November 03, 2013, 08:17:30 AM »
Hey everybody :)

I'm looking for a little advise to hopefully allay my focussing issues with my Canon 400mm f/5.6.

I was out birding two days in a row where my lens would just not focus on anything in flight. I know on two occasions, my centre focus point (Canon 500D) was slap bang on a bird but the lens would not focus lock.

I experimented by focussing on reeds about 4-5 meters away then focussing on some buildings in the distance, it locked nearly 100% of the time with a very minor lag. The only time it did not focus on the building was when I tried focussing on a white wall, bathed in direct sunlight causing noticeable glare.

A more experienced photographer advised that its not my lens, its due to the cloudless sky being completely monotone blue. He mentioned the sharp sunlight is not giving the lens anything to lock onto.

You guys agree with his assessment? And birder with a 400 f/5.6 also experienced a similar result with her lens.

I had a USM motor of a Canon 100mm macro pack up for no reason and I'm worried this lens may be experiencing the same issue.

Thanks in advance for any advise/experiences everybody  :)

Speedlites, Printers, Accessories / Canon Ring Lite MR-14EX Serial Number

Hey Canonistas :)

Anybody know where the serial number is on the Ring Lite? Is there even one?

Needed for an insurance quote

Thanks everybody :)

Lenses / 24-70mm f/2.8 L mkII & 50mm f/1.4???
« on: October 22, 2013, 02:29:34 PM »
So I just bought the Canon 24-70mm f2.8 L mk II yesterday and as luck would have it, was just offered a brand new Canon 50mm f/1.4 for a very, very good price.

So the question is, should I buy it? In fact, with the vaunted performance of the 24-70, does it still make sense to buy a 24mm, 35mm, 50mm or any other prime in that focal range?

I am thinking the only plus to those primes would be better bokeh, or am I being short sighted here?

I'm still learning this photography thing so apologies if my questions rankle.
