I was wondering if anybody else owning a Canon-spec Sigma 30mm lens experience the same problems where its AF distance estimation is not very accurate. The resultant DOF quite regularly end up in front or behind the focus spot. Which naturally ruins the feel of the picture. I have been trying...

The custom dial modes that i preset are based on settings that i estimated to be "average" among the environments i would be photographing. But of course, there are often cases when i need to further adjust those presets to properly match the current situation. e.g. C2 set to AI Servo; Zone AF...

When i was utilising a Canon 450D, the Tamrac Velocity 7x was a suitable fit even with battery grip and other accessories. Now however, i operate a pair of 7Ds + battery grips + R-strap connector, because i dual wield with different lenses. The Velocity 7x has been a squeeze for a single 7D, and...

I am trying to think of good techniques that can capture the full vibrant scene of outdoor night or poorly-lit events at wide angles. In my previous experiences, flash fitted with wide-angle plate or diffuser is usually still not enough to illuminate an entire ballroom nicely, and certainly...

Less than two weeks ago i was covering a two-day sport event. Duration was a couple of hours each evening, so i netted around 1600 pics per day. Since i didn't have a secondary camera (with wide-angle lens), all I focused on were action photos with 7D and EF 70-200mm f/2.8 IS, whacking AF Zone...

Has anybody bought the BG-E7 and wondered how this thing is actually weather sealed? There just isn't anything that visually gives me confidence it's all tight. Seems i'm not the only one having doubts http://www.flickr.com/groups/1246778@N22/discuss/72157624798712813/

My eyesight's failing me. i find it harder and harder to accurately determine the sharpest focus distance when tweaking in MF. Worse when looking at wide-angle views. Even worse when in low light. I need something to magnify the viewfinder so i get a bigger clearer picture. What are some...

I use single focus point (mostly centre point). back with 450D, the point that was used will blink its dot red when focus was acquired. now with the 7D, i find no option to make only the particular focus point blink. The entire VF overlay will illuminate red (after forcing it in CIII-8 to...

when i use Canon DPP and Photoshop CS4, i can freely manipulate the tone curves with multiple points whichever direction i want. now i am perplexed why Lightroom 3 only allows adjusting the curve on a straight vertical axis at any point? This prevents me from shaping the curve in a hump form...

need a container to hold my drink. http://photojojo.com/store/awesomeness/camera-lens-mug/

I understand that there are various 3rd party remote shutter controllers for 40/50D that are compatible with 7D. Is there a site that provides side-by-side analysis or comparison for each available product?

when i first attached a batt grip to my 450D, i opted for a Matin strap and it felt well-sized and tight. now when i tie the same strap to my 7D+grip, its size and weight makes it feel thin and understrength. Now i know it will hold, but the feel is not snug. i probably need a thicker, broader...

I notice when i load Raw photos from 7D into Canon DPP, there are some preset NR settings which I did not configure (e.g. Luminance 4, Chroma 11), even though i shut off every NR setting in the camera. They are already applied, to which I have to further increase the NR values in order to reduce...

I'm sure many of you already know: there is a BE EMPOWERED by Canon contest in Facebook to send your self-portrait with your equipment. http://www.facebook.com/pages/BE-EMPOWERED-by-Canon/286731937882?ref=mf http://www.canon.com.sg/digitaldreams/empowered/

so it seems Sandisk extreme IV is no longer in production. What's left is the Ultra (30MB/s) vs plain Extreme (60MB/s). have other 7D users attempted Ultra with 8fps? how's tje performance?

If you don't enable private messaging. there's no way i can PM you. I use 24-70mm for anything I want, so as long as the range and angle is right. To take people, to take objects, to capture a medium-angle scene. Yes it has more or less replaced my use of the 18-55mm lens. wide angles i use...
