How to quickly change a lens

I have to say I'm not the fastest man on the planet so I did some search and found few good videos. Take a look yourself.







Which technique is the best in your opinion? Or perhaps you know the better way?

Sigma review

I'm not a photo equipment expert so instead of writing standard review (which you'll easily find in photo magazines or websites) I'll just write down what I like and don't in Sigma 10-20mm f/3.5 lens.

What's good:
  • super wide angle (actually you can't get any wider) and 10-20mm zoom flexibility
  • constant aperture of 3.5 which is really decent light
  • contains HSM (Hyper Sonic Motor) thanks to which it works really fast and quietly
  • good autofocus
  • distortion is fairly small
  • didn't spot big vignetting (read about that in some reviews)
  • really well done and not too heavy at the same time

What's not:
  • it could be sharper but it's not too bad. Slight sharpening in Photoshop does the job.
  • lens hood attachment is done really bad so the hood just slips off. I almost lost it twice... thanks to the people who pick it up and gave back to me! :-)
  • filter size is 82mm so it's very expensive (yes, I knew it before buying)

    Basically I really enjoy shooting with new Sigma lens. It's definitely a great choice for those who can't afford or don't want to spend too much money (Nikon or Canon lenses) on a wide angle. Anyway wide angle (especially so wide like Sigma 10-20) is a must have.

    New baby has arrived!

    And the winner is… Sigma 10-20mm f/3.5 EX DC HSM




















    Yup, the brand new lens has been delivered just a couple hours ago. Why Sigma 10-20mm? Sigma has range of focal lengths which suits best my needs, good light (it’s not 2.8 but still fixed 3.5 is not too bad) and HSM system. I’ve also read many reviews, tests, opinions and everywhere Sigma had high ratings. It’s a bit more expensive than an older brother (Sigma 10-20mm f/4-5.6) but has better light and as far as I know few things were improved.

    I haven’t had a chance to test it yet. I’m waiting for the weekend and the Festival of World Cultures where hopefully I’ll take loads of good shoots :-)

    So this is also a qucik reminder not to miss this weekend in Dun Laoghaire!

    Wide angle lens

    It’s a shame to admit but I don’t have a proper wide angle lens. Yes, I do have a kit one which is 18-55 mm and a universal range lens 24-70 mm but in lots of situations it’s just not enough. Anyway it’s the decision time! I hope I’ll chose wisely and maybe some of you’ll find my way of thinking helpful in making your own choices.

    I already had a closer look what’s available, read some reviews and asked people but still haven’t made up my mind. The choice is even harder because there’s a variety of brands and models in wide angle lenses class. I’m looking for something from 20-24 mm (my main lens is 24-70 mm) and of course the wider the better. Price I’d say is 700 euro max. Initial selection gave me the following list of lenses...














    Tokina AT-X 124 PRO DX II AF 12-24 mm f/4














    Tokina AT-X 116 PRO DX AF 11-16 mm f/2.8














    Sigma EX DC HSM 10-20 mm f/3.5













    Sigma EX DC HSM 10-20 mm f/4-5.6














    Tamron SP AF Di II LD Aspherical (IF) 10-24 mm f/3.5-4.5

    All of these lenses are from 550 to 650 euro. All prices are from Dublin stores.

    As soon as I decide and buy it I’ll share this happy moment with you. I’ll also write a bit more about each of these lenses and explain my decision. Stay tuned!
