Filter for Canon L lens

I just got my first Canon L lens and after some research, I decided not to buy a UV filter as protection for the front glass element. Then I can read the presentation (B & H) for the EF 16-45 mm F/4 L, which States that "when paired with an optional filter to Protect, this lens also features a dust and water resistant construction for use under adverse conditions. So now I'm confused: why a $1,200 L lens does need a "Protect filter? By "adverse conditions", what do mean? Should all lenses L be fitted with a protective filter? What would be a 'protective filter' recommended? I'd appreciate some advice on this because I want to protect my investment in my L lens and consider making a recommended.

Some 'L' series lenses are waterproof. If you see a black silicone gasket to the mounting flange back, then chances are it's a goal and waterproof. But you have to read the instructions for each specific objective know what it means. A few lenses indicates that they are only waterproof only if a protection filter is attached.

Weather sealing means that the lens is usually sealed against dust, rain and spray - but it is important to remember that this does NOT mean that the lens is "tight". They are not sealed against water under pressure. If you blast it with a spear of fire... you will probably get water inside. Similarly, they will flee if submerged. There is "underwater camera housings" available when you need the camera & the goal of being ready to go under the water.

Furthermore, just because a lens is weather-sealed does not mean that the body of the camera is waterproof. Only some camera body get weather sealing and the level of treatment varies. Usually, intermediate and superior camera tend to have at least one treatment of the weather sealing, but even in this case, there are some obvious gaps. The door of the memory card and battery door are two examples of places that have no weather seals.

Other than that... There are a few downsides to having a UV filter.

First of all, the camera has an internal UV filter, so the second filter does not really offer help in this Department.

Second, a flat glass filter, it is able to create nice reflections that can be seen by the camera. This can create 'ghosts' reflections and other effects undesirable undersireable. The use of filters with anti-glare coatings will substantially reduce this problem, but these filters cost a bit more. Also, they will simply 'reduce' substantial reflections but do not guarantee that you get no thoughts at all.

The glass itself is durable enough. Be gentle with it when clean you and you will never have a problem (use a soft 'clean' microfibre cloth). The sun visor (even if you are not trying to protect from the glare) actually helps keep something striking the glass. The hood is probably better protection than a UV filter.

Canon Zoom lens

Hello world

wish you all agreat day,

After the Suggestions in this forum for my camera so my first goal... Thanks guys I bougth the Canon 6 d and bought the Canon 17-40 photos of couple in my first Attcched lens...

Now I'm looking for a zoom lens, any suggestions? with good quality / mony? Honestly I do not put a budget for it still don't intend to but something so dear, my favorate style is architecture & urban landscape, but some times I may need a zoom so out for some shots my need more than what I have now (canon 17-40).

Thanks for the passage & thank you for the support.

Concerning

But what would you use for? That tells you what focal length to get.

You already have the range of 17 to 40 covered. Which can be used for your walk around lens that it stops a little short for this to 40 mm. I use a 35mm Prime than my walk around and I Zoom with my feet so I think you can also.

For a standard telephoto lens that is the EF 70-200mm L f/2.8 IS Mk 2. In the United States, he sells between $1 800.00 and $300.00 2. It's a fantastic lens. Sharp. Many colors. Ideal in low light. Great bokeh. And the focal range is very usable on a full camera frame. Not often is too long to be useful.

If you need a longer telephoto let us know and people can suggest lenses longer but the good ones cost dear and you can also lose the opening f/2.8 nice if you get a telephoto lens more long. Unless you really spend a lot on a 300 mm f/2.8 or 400 mm.

extension for Canon 6 d tube

Hello, I'm looking for an extension tube for my Canon 6 d. I found a few different brand offering a set 13, 21 and 31 mm sets. They don't specify if they support the auto focus. I would have preferred a set that support of the auto focus.

Do you have a suggestion? Thank you

The tube macro set that includes the rather odd size 13mm, 21mm and 31mm made by Zeikos and sells a whole bunch of different brands (Bower, Vivitar, Jessops, ProOptic and many others). There are two qualities of these tubes, one with metal bayonet comes up and a less expensive version with plastic bayonet rises (as have some kit lenses). The bodies of these tubes are plastic and they support control AF and openness. All the facts for Canon will be fit very well on the your 6 d EF mount (someone with a Canon of harvest/EF-S camera will have to take care to buy later versions of these that support this mount if they want to use with the EF-S lenses, some more before those who do not). These tubes to sell for less than $100 US (the bayonet plastic are often closer to US $50). Three things worry me to their subject: they seem not very durable, I've heard some reports of their cracking over time. Release latch is a little beyond and can be accidentally pressed. And I've seen a few reports of them "frying" the circuits of the Canon 5 d models. The latter seemed to be very isolated cases and 31 mm tube seemed the culprit. I have not seen all the reports of problems with other Canon models.

Opteka is doing a set of tube which is similar in construction - plastic body with mount bayonet metal - which also sells for less than $100 USD, but includes more traditional formats of the tubes of 12 mm, 20 mm and 36 mm. They also support the AF control and openness. The release button is slightly off, but I haven't used these and can't tell if it's much better that the tubes Ziekos (etc.). They are a relatively new feature, so only time will tell how sustainable they are.

The Kenko tubes set's metal body and metal bayonet mounts, more comparable to the tubes that Canon are available (but only individually). Kenko all contained 12mm, 20mm and 36mm and sells for about $200 US. Older versions of this set (labeled "CA/AF") are the only mount EF lenses. Current version marked ' CA/AFs' (note the small 's') is used with the EF and EF-S. Of course, either will work on 6 d and EF lenses. The Kenko tubes also support the AF control and openness.

Canon offers only individual tubes: 12 mm and 25 mm. The older original type are EF. The current 'Mark II' are EF a EF-S compatible. The construction is very similar to the Kenko and totally supports the AF control and openness. Indeed, Kenko also offers individual tubes in the same size. Both the Canon and the Kenko use a release button recessed enough that it is difficult to accidentally fall. Currently, the Canon tubes sell for about $85 for the 12mm and $140 for the 25mm.

Finally, there are macro extension tubes really inexpensive who do not have electronic contacts to provide the AF control and openness. They are usually all metal construction, use different locking mechanisms and sell for less US $25 (sometimes even less than $10). Sizes included in a set usually are 12 mm, 20mm and 36mm.

To be honest, who doesn't not AF during macro shooting is not really all that big a deal. It is often easier to focus manually blows high magnification. I often switch off AF and several of my macro lenses are put to manual focus only. Focus you by moving all camera and lens more closely or to keep him away from the subject. The lens ring, kind of serves more as a zoom, defining the degree of expansion. The fine adjustment of the development is done with the movement of the whole platform. This can be done by hand, or there are tools such as the stages of macro development prevail. allowing that with a high degree of accuracy... or with a lens that has a tripod mounting ring, if you use the Arca-Swiss quick release system, it is possible to use a plate of extra long lens like a development of "slider".

More of concern is the ability to directly control the aperture, which is done electronically with gun and camera objectives, through controls on the camera body and the electronic contacts linking the two. High magnification means shallow depth of field, closing the diaphragm is often necessary. There are ways to vary the opening with the really cheap tubes that do not have electronic contacts, even with the modern camera and lens. But it's a pain in the anus. Personally, I would only use and recommend the really cheap tubes for use on adapted lenses, vintage which have a control ring of the aperture on the lens itself.

But most tubes discussion (Canon, Kenko, Zeikos/etc. and Opteka) provide electronic contacts, so control AF and the opening are fully supported.

What purpose do you intend to use with the camera and extension tubes? More focal length, the extension you will need to significantly increase the magnification. But too short focal length can put you too close to the subject. Mostly for use on a FF camera a lens in the 70mm to 135mm range is a good compromise of adequate working distance, but handholdable and not requiring not too much expansion. You can stack many tubes for a whole bunch of extension, but it can become risky with too many tubes. Best to use as little as possible.

I'm a big fan of extension tubes... were their use with various systems for 25 + years and always have some on hand just in case they are needed. They can also improve the ability to narrow focus of a large telephoto lens. They are easy to use and having no light inside, have little negative effect on the quality of the image.

I currently use with my kit Canon Canon 12 mm (2 X), 25mm and an older set of Kenko. Over the years, I have used lenses from 20 mm to 500 mm, 24-70, 70-200 and 28-135 mm Zoom. I sometimes use with macro lenses, too... to stimulate their magnification higher that 1:2 or 1:1 the lens alone offers.

My recommendation... Buy a good game and you're going to buy them only once. There is little wear and macro extension tubes are versatile, useful and easy to slip into the corner of your camera with you bag all the time. IMO the Kenko game offers the best value (but I have not seen or used the new Opteka set has been presented, so can't really compare).

Filter for Camera Raw in Photoshop cs6?

We all know that in the window of the filters it is a: the filters Gallery, wide-angle adaptive, correction of the lens, fluidity, painting in oil, vanishing point, but I have some, watching videos, as the filter "filter camera raw" is there not.
You know how can I have it, get it back? I wonder why he is not part of my filters?
I reinstalled my software and it is still missing.
Hoping someone can help me.
Thanks in advance

The crude camera filter is in CC version. CS6 doesn't have this filter.

Filter for table data, the range of data obtained and defined 2D

I produce data of an ultrasonic sensor at 1 K Hz, and there is a lot of data (data points range of 0 to 10). However, in some cases when I know that the data should be about 7 (for example) I get outliers (about 9 and 10). Is it possible to define a filter for data in the defined range.

I averaged the data to get an average value, and outliers are distorting. In the worst case, my outliers are 30 to 40% of the data generated. I created a filter to sort the data and, taken from the lowest value. I stop the loop when data reaches a value greater then 9. But this seems to take a long time (because the loop checks for each data point and there are 1000s of them).

Is there a better way to filter data and define a predefined table range to collect?

I enclose my filter.vi... and a set of samples of my previous data. The ranges of data of 10-8 and would like to have the range 7.5 to 8.5 to consider. The sensor records tension here and the problem can be solved by installing a different type of sensor, but if a filter in LabView can due it, the sensor that we use now is absolute.

I am in kind of emergency, my design in unfinished because of this problem, if someone can find some time to share some suggestions, I will be grateful.

Thanks in advance.

See attachment. I have incorporated the data you've posted in the vi. It doesn't seem like any data were less than 8.7 or so, so I modified the scope so it would be a few points on average. Some games were completely out of reach while the average came back like NaN (not a number) due to a division by zero.

Looking for a new lens

I have a T1i and am looking for a new lens for an upcoming trip to Italy. I am currently using a 28-135 as my lens every day and wonder if it is better to use as my daily lens out there to be able to capture the sights. I'll be bringing in a 50 mm fixed, but do not want to be bogged down with too many Lenes

The EF 28-135mm f/3.5-5.6 IS USM is a great lens. I'd be willing to take just about anywhere.

You said that you have a 50mm f1.8, I think. I would take what you have and add the EF-S 10-22mm f/3.5-4.5 USM or the new lens EF-S 10-18mm f/4.5-5.6 IS STM.

But the EF 28-135mm f/3.5-5.6 IS USM and the 50mm f1.8 will cover "more" than what you need.

Driver for Canon Pixma IP4600 printer

I had to reinstall Windows on my PC due to obtaining a bad virus. My Canon Pixma IP4600 printer worked before the re - install, but now windows can't find a driver. I spoke to Canon and they said that they offer is no longer supported, but Windows should continue to support and drivers must come from there. I tried a driver through Control Panel, but it is said that a driver is not available. This printer is not that old, so I can't believe that there is no driver available to all. Can you help me please?

I'm sorry, but as I explained Microsoft does not write drivers for Canon products.

Microsoft writes and provides drivers for their own products.

All drivers that Microsoft may provide in their OS for Canon products provided by Canon.

I suggest that contact you Canon and get them to set this output or first try the Vista drivers.

Kind regards.
