Lenses / Re: Best filter
« on: March 13, 2013, 08:25:22 PM »
For you, I recommend the B+W F-Pro Gold MRC UV.  Unlike all those plain, black-ringed filters, that one is a shiny gold color and looks really cool (which is very important, as you know).

Here are the videos. I do not see a difference.

The point wasn't a video with the hood, but OF the hood.  Don't bother, just enjoy your cool-looking (but less functional) petal hood.

Long exposure NR (where a dark frame is taken after the exposure and subtracted) is applied to the RAW image.  No other form of in-camera NR is applied to the RAW image.

I opted for the MH-01 LR as sometimes I need to swap bodies/lenses  on my mono.

Love the LR clamps, but I picked the screw clamp for the monopod because I often carry that rig over my shoulder, and was concerned about the lever catching on a pack strap.

RRS. It really is the right stuff. Really!  I have the TQC-14 + BH-30 for travel, and the TVC-33 + BH-55 and the PG-02 LLR gimbal, MC-34 monopod with MH-02 Pro head, macro rail, etc. - it's all top notch.

Manfrotto is about the ideal compromise between quality and value, IMO.

Plus, it looks cooler.

Clearly, the most important criterion when choosing a lens hood...or any gear, for that matter. Can I interest you in the special Jackie Chan edition of the 550D?  It's more expensive than the T2i, but it looks really cool!

However, I bought it as a recommendation from sites.

I ran across a site with recommendations on how to jump off the Golden Gate Bridge. I guess I'd better not post the link...   :o

The petal hood has come in. There is NO vignette with the 18-55mm.

Well, that's good.  The point of a properly-designed petal hood is that the 'petals' can stick out beyond where the baseline of the round hood would be, based on the rectangular shape of the sensor vs. the round shape of the image circle.  Since the petal hood you bought does not vignette as it rotates around, that simply means the 'gaps' are recessed from the baseline where the round hood would extend, rather than the petals extending beyond.  In other words, the hood you bought will most likely offer less protection from flare than the round hood designed by Canon.

But hey, lots of people prefer looks over function, so you're in good company there.   :)

This sharpness issue wont effect a RAW image will it?
Noise reduction isn't applied to RAW captures I believe.

Only Long Exposure NR is applied to RAW images.

Is this true (electronic first curtain) for other camera models as well (E.g. 5d3), or just the 1dx?

It's true for almost all of them, although with the higher end cameras (like the 7D, 5DII/III, 1-series) you have to have it set to the default Silent LV Shooting Mode 1, i.e. disabling Silent LV shooting means no electronic first curtain.  With the lower end cameras (Rebel/xxxD, not sure about the xxD), EFC is always on for LV shooting.

It works if you just hold the button down after the shot and walk away :oP

Actually, the real solution for a silent shooting mode on the 1D X is just to shoot from further away:

So in theory, mirror locked up, live view shooting could be a kind of silent mode?

Yes, Live View is quieter than regular shooting.  It also uses an electronic first curtain shutter and that eliminates another  source of vibration - that makes Live View ideal for tripod-mounted shooting of static subjects.

Agreed - the shutter needed to be robust to move at 12 fps and last 400K cycles, I suspect they made it as quiet as they could...

I wouldn't think the shutter drove the design as much as the mirror mechanism. Shutters have been capable of opening and closing over the frame at 1/8000 sec.
You're right, of course.  I meant mirror (which also has to flip at 12 fps).  Although the shutter makes a slight contribution to the noise, most of it comes from the mirror.

I primarily shoot Macro (180mm 3.5L and 100mm 2.8 USM with twin 430EXIIs or twin 270EXIIs on a Manfrotto macro flash bracket) and  I also shoot outdoor landscapes as well as a few of family and pets.

If you've got plenty of light, the IQ of an APS-C sensor is good - definitely sufficient for 11x14 prints.  Better quality lenses (EF-S 17-55/2.8 vs. the 18-135, for example) will likely do more for your IQ than a FF sensor.

To test tripod stability, you can use Live View 10x and tap the legs or stomp the floor/ground.  Also, try several conditions - +/- mirror lockup, center column up, down, removed, etc. (you'll quickly find that you don't want to raise the center column!).  You can also try taping a laser pointer to the lens...

Weight ratings are good for comparing within a brand, not really across brands.  For example, I also have the RRS travel setup, the TQC-14.  It's rated for 11 kg, but I can literally suspend my own weight (82 kg) under the tripod hanging from two of the legs!

A stronger head might help a little, but I expect the difference between the two heads will be pretty minor.

Could it actually have both DSLR-like AF and an EVF?

Doesn't the reflex mirror required for phase detection AF force you to use an optical viewfinder?

They could bring back the pellicle mirror, but angled the other way.  Actually, such a system (reverse-angled fixed mirror and EVF only) would remove the geometric limitation on AF point spread, in theory allowing phase AF points to cover a much larger area of the field...
