Lenses / Re: UV Filter damage limitation on 16-35II

A lens hood would help a lot in this specific case.

The Sigma is much more artistic :)
Yes! It has to be part of Sigma Art series  ;D

To tell the truth if I had none of the 3 I would be very confused...

The 801D charger lasted a few years. So no hard feelings. However, the first that stopped working was the slow charge!!!
So I had no other option that to use fast charge.

My only complaint was that the way it broke down was very dangerous.

I believe that your charger will serve you some years. Just keep an eye on it...


If you want to try another option, the Lacrosse Technology BC-1000 battery charger is also top of the line.  Not inexpensive, but so far very reliable.  Has an LCD for each battery so you can see what's happening to them.  Goes through cycles of slowly discharging them and recharging them to get the best charge, or also by faster charging them at your discretion.  Just does four at a time, AA or AAA, but not intended for Lithium.
I got the Maha/PowerEx 9000 model. So far so good. They only (slight) problem is that it refuses to charge some older NiMh batteries. But it is a nice combo with Eneloop batteries.

Lenses / Re: EF 135 USM L or EF 100 Macro IS USM - which one is sharper?
« on: October 01, 2013, 05:14:44 AM »
even better the Sigma 150,which is actually sharper than both the 100L and the 135mmL.
Very funny! Is this sharper (especially at full aperture as OP asked)?

Based on those charts, the Sigma is not as sharp... the 100L seems to beat out even the 135 F2 wide open. At F2.8 both are very close.
Exactly my point!

The IS on the f4 L IS isn't quite as good as the one found on the f2.8 II version
Says you. Canon says otherwise (that they are equal).

In my experience, they are similar, which means highly effective.

The IS on the mk II 70-200 f2.8 L IS is quieter and visibly smoother in the viewfinder. The unit on the f4 LIS is very effective but it's a fair bit older in design than the newer f2.8 version. There's a number of reviewers who have stated that they found the f4 LIS to be slightly less than 4 stops ability and the f2.8 II LIS to be slightly over. Regardless of outcome, both are very capable units and very capable lenses.
The IS on the mk II 70-200 f2.8 L IS is indeed much quieter. However, my f/4 L IS seems 4 stops effective while my f/2.8L IS II seems ... 1 stop effective! True this is my subjective view due mainly to lens weight but the end result is the same for me.

That's the objective part...
that said, it's still very capable. The f2.8 has twice the brightness and the same level of IS, so you gain a stop in low level shooting. But it's a heavier and harder lens to handle, so I think that the extra stop is lost due to the size and bulk of the f2.8 version. The f2.8 version can melt backgrounds a little easier but focus accuracy becomes more critical as the depth of field diminishes.
Now we agree! Since I have both allow me to say regarding the f/4 IS version:  its IS combined with the lower weight - as you also say - makes it a killer combination. That's me. Other members find easy to handhold still a heavy lens. That's the subjective part...

The Powerex Maha MH-C801D Eight Cell is the one that I use. It's a great charger with built-in battery deep-conditioning system, and selectable soft and rapid charging.
Until it decides to fry your batteries ... melt its own plastic by not stopping charging. It has happened to me!
In addition, it seems I am not the only one (judging from Amazon.com feedback on this product)...
(The first that stopped working on my charger was the soft charge button...)

Thanks you, Sir, Dear Tron.
Thanks for your infor.
Now, Poor Surapon---Now What will I do, 2 sides of Powerex Maha MH-C801D= Good  or ----Bad ???
Thanks.
Surapon
I have not given up on Maha because of that (I do not know though if it this was wise). I got the Maha/PowerEx 9000 model that is a more sophisticated charger. Unfortunately it charges only 4 batteries at a time. I have it for almost 2 years and it has been fine. No complaints apart from the fact that it refuses to charge some older (but in good condition) batteries.

I too have both the f/2.8 and the f/4 versions of the 70-200 IS. The f/4 is unbeatable for size/weight. Its IQ is also very good.

I used the 2.8 II only in one occasion where I needed the fastest possible 70-200 optic. That has given many good photos but except from such (and rare for me) special cases the f/4 is enough. I can even put my 5D(II or II), 24-105 and 70-200 f/4 IS in a small Thinktank Urban Disguise 30 and still have room for a small optic or flash.

The only thing that stops me from getting 70-300 is that the overlapping would be too much - and no I will NOT sell 70-200 f/4 IS - and the reverse use of focus and zoom rings.

To sum up: It seems difficult to choose. I would rank Nature People/pets Event and Travel categories and then choose accordingly.

Speedlites, Printers, Accessories / Re: Choosing the right tripod
« on: September 25, 2013, 11:28:48 AM »
I moved from a Manfrotto 055PROB + 410 Junior Gear Head (total ~3.7Kg) to a Gitzo 3541LS + Markins M20 head (total ~ 2.3Kg)

This proved to be a night and day difference in weight for me. It cost a lot but now I am able to take it with me more often.

I believe this is overkill for you. You should try to focus on a Carbon Fiber solution though. A rather expensive but light tripod that you take with you is better than a cheaper heavy tripod that stays at home.

Keep in mind that for tripods you can have only 2 out of the following 3 characteristics: Cheap, Light and Stable.

Embrace it, enjoy it, buy the rest of L lenses  ;D  ;D  ;D
