EOS Bodies / Re: Is there something wrong with my 5D Mark III?
« on: July 28, 2014, 03:57:05 PM »
I must say that I NEVER use my Canon 50mm F1.4 at apertures larger than F1.8, it is admittedly low contrast and low sharpness.

Whereas Nikon 85mm F1.4 costs at least three times more expensive, it is quite obvious that it will have better picture than Canon 50mm f1.4 when used wide open.

Yes, AWB Canon misses a lot and tends to orange colors. So I also NEVER use AWB.

Probably the hypothetical Canon T6i will be something like a 70D with plastic body and without AFMA.

EOS Bodies - For Stills / Re: HUMIDITY ALERT!
« on: July 20, 2014, 07:27:48 PM »
ajfotofilmagem,
Any UV system generates ozone, with accelerates decomposition of rubber or many polymers.  The attack is worse than the drying of the gasket material.  Don't use UV, chlorox ect., to prevent fungal growth.
Most household moisture level is well over 50-60 percent, and fungal is still minimal.
I bought some plastic boxes, like the one you can get at big box store, the orange, grey/blue hardware stores, and the big blue discount grocery super store, so I can organize my gear and external disk drives.  I am sort of having second thought of the idea.  Coupled up in the sealed boxes, the air gets stale and things can grow inside with little moisture.  So, I keep the lid skewed, just to get circulation.
Someone on another thread got a drawer set for gear storage.  I think that is a wonderful idea.  Keeps dust out, moisture level at comfort range, and cool.  Rather inexpensive, to boot.

Yes, ultraviolet light causes deterioration of rubber. However the spectrum of UV-C light is much more eficienye that natural sunlight, and takes just a few seconds of exposure to kill the fungi. I have used a few years (once a month) and have not had problems with the rubber of my lenses.

One question or concern:
If the environment is too dry where you store your gear, will it over-dry the seals, specifically, the O-rings, foam shock absorbers, etc., so they'll crack or disintegrate too soon?  There must be a range of humidity where fungal growth is inhibited without the gaskets getting too dried, thus too much desiccant can't be good.

Many dehumidifier apparatus heat the air, and this heating can dry rubbers and lubricants into the lens. I believe humidity below 30% is sufficient to prevent fungi.
 

Is there another way to prevent fungi:
Aquarium filter with UV-C lamp.



These filters have a lamp that produces light in the ultraviolet-C, which destroys the DNA of cells and kill any living being, including fungi. Instead use in aquariums, use in their lenses. Just unscrew the UV filter lens, point the opening of the hose to the front and back of the lens. Watch out! Use dark gloves and never look directly into the UV-C light, which is highly carcinogenic in humans.
The rays of UV-C light are also produced by the sun, but do not reach the planet because they are filtered out by the atmosphere.

Canon General / Re: New Speedlite Coming? [CR2]
« on: July 17, 2014, 05:51:14 PM »
Wow, no one stating the blindingly obvious feature that canon should put in all their flashes ----come on now, how hard is it to put a freaking battery meter in there?  It would be so awesome to be setting up my lighting and turn the units on and know....ohhh it's got 3/4 power left, no need to change batteries, or wow, 1/4 left, better put some new ones in.  The 600 really really should have that!!!  so I won't hold my breath on a 400 series flash having such a simple feature --------- it really boggles my mind why it's not there.  Maybe I'm the only one that's bugged my this????
I agree entirely. Current technology allows measuring battery with great precision, and there is no hindrance to put it in a flash that costs hundreds of dollars.

A particular type of battery would trigger the low battery warning when remaining 10 shots (maximum power), and other type of battery would trigger the alert when 30 shots left. But at least we would have a reliable estimate to repeatedly use the same batteries.

A thermometer would also be good, since it does not arbitrarily turn off the flash (Nikon SB900).

Lenses / Re: Camera setup for dental clinic
« on: July 14, 2014, 09:03:57 PM »
A camera with LIVE VIEW will greatly facilitate to photograph the teeth inside the mouth. An APS-C camera makes it even easier because of the depth of field wider. If the camera has an articulated LCD, will be great. I recommend Canon 70D + EF-S 60mm macro + ring LED continuous light.
See the link for a suggestion LED light ring.

However, any current Rebel model will do a decent job. Both Canon 60mm and 100mm macro has great picture quality. The advantage of the 100mm L is the Image Stabilizer, and sharpness a little higher, and the BOKEH when used in F2.8. But for the photos of the teeth you will often use F11, and then the quality of the lens will be the same.

Technical Support / Re: HOW TO USE THE NEW BATTERIES ?
« on: July 14, 2014, 04:17:16 PM »
Dear friend Surapon. Unlike wine, the batteries deteriorate over the years, and keep them without use does not prevent them from deteriorating. Specifically, the Ni-MH batteries should be stored discharged, to prevent premature aging. The exception of the great ENELOOP, which has a special chemical composition for longer life.

As you have 4 batteries, you can number each one and rotate to all be in use. If you think you can take months without using a particular battery, keep it uncharged to preserve it.

Software & Accessories / Re: To filter or not to filter

I prefer to use lens hood only, to protect most of my lenses. Lenses from $1000 I use UV filters for added protection.

I would not walk down the street alone with a lot of photographic gear. :-\ In fact, when I travel to potentially unsafe cities, take my cheaper camera with a zoom lens. :-X

EOS Bodies - For Stills / Re: New body for better focus system
« on: July 11, 2014, 04:29:03 PM »
Full frame will require more expensive, heavy and large lenses to display sharper images in the corners. The problems you describe could be resolved 5D mark iii, but the sum spent on body and appropriate lenses to replace its current, starts at something like $5000.

70D has more reliable autofocus, and AFMA to fix their lenses. 7D Mark II will be released in a few months with 99% certainty, but can cost up US2000, or perhaps only image quality equal to 70D.

Dear "J,"

I supposed I should not be surprised that you chose to announce the end of our relationship in such a public and cowardly way. You were never one for subtlety and discretion.
And, so typical of you to blame all the failures on me. As though you contributed nothing to the breakup. But, then, I guess since you contributed so little to the relationship, I should not be surprised.
The truth is, I've known for a long time this wasn't working. If I could have ended things myself, I would have. But as you know, for me this was an arranged marriage. You picked me and I had no say in the matter. For the honor of my family (and honor is something my culture values very highly) I could not leave you.
At first, your clumsy attempts to satisfy me were amusing and not without a certain boyish charm. But, honestly, it quickly became apparent that you were never going to improve. In fact, I soon realized that you actually thought you were good. I know this is hurtful to say, but since you are the one that began this public conversation, I think honesty is justified.

Never once were you able to bring me to my full potential. No, let me be more candid, never, ever did I come remotely close to achieving the heights I was intended for. You would fiddle with my dials and move my joystick, but it was so mechanical and uninspired that I could hardly bear it. Honestly, most of the time I wished you would just stick to the green box and let me do it myself.
And the trips...well, what can I say? Sure, I enjoyed them, but it was as though you thought that simply going someplace new would solve all our problems. All it did was make me long for the relationships that I saw others enjoying. How I wished that could have been us. But you...all you ever did was worry about whether someone else had a newer, prettier model hanging on his shoulder. 
You were so obsessed with showing me off that you didn't see how many of your fellow travelers lovingly treated their lowly Rebels with respect and appreciation and how they were rewarded in ways that you and I could never achieve together.
Yes, I saw the world. But, really, I would have traded it in a instant for a quiet little town in the Midwest, with someone who understood me and what I was meant to do.

Now, dear D810, believe me, I wish you no ill. In fact, I actually feel sorry for you. I know people say you are nothing more than an overinflated mass of silicon, but I know better. We are both from established families and, like me, you have not had any say in this relationship.
I would like to wish you a long and happy relationship, but I suspect that won't be the case. In the end, you will be blamed for everything. Just remember this. It is not you...it's him.
Dude, you saved this my hard day. Thank you UNFOCUSED.
