Thank you!

Got some dust on the glass or frosted viewfinder (which is located above the mirror). What are the options or cleaning methods?

14.06.2009 22:34:00

What are the options or cleaning methods?
drink brandy 100g, score and sleep

14.06.2009 22:38:00

and seriously. Because they can be seen. Is it possible to extract the viewfinder window and clean the special napkins?

I easily obtained without brandy.

I easily obtained without brandy.
cognac is for those who are wondering, the guru of clogging dust can live without it



first make sure where they
on the frosted glass and mirrors clean hands if you can fit just fine (many materials, as discussed here and on klubfotoru )
about himself viewfinder not prompt

14.06.2009 22:58:00

Literally on this page has all the necessary links.

14.06.2009 22:58:00

What are the options or cleaning methods?
I believe that if you read this page just below the start - the answer will be found.

14.06.2009 23:16:00

,

thank you very much for intelligent answers! Vtakayu .

14.06.2009 23:20:00

Horrible some dust on the glass or frosted viewfinder (which is located above the mirror). What are the options or cleaning methods?
Pear blow. Helped me - everything is clean.

And you have Goblin online also write? Read http: // photo. oper. ru / torture / read. php? t = 1045689262

Take, say, fifty dollars 50 / f1, 4. On fulfreyme he, not surprisingly, behaves as fifty dollars 50 / f1, 4. On sprinkled he behaves like the equivalent of 50 ( DF) * 1, 6 (crop factor) = 80 mm, t. e. of the standard is transformed into a weak body - almost everyone knows. However, many do not know that it is equivalent to the minimum aperture value also changes - is transformed into 1, 4 (F) * 1, 6 (crop factor) = F / 2, 24!

That's about it for the first time I heard, like here in the themes of lenses not slipped, or read carefully. . .

That's about it for the first time I heard, like here in the themes of lenses not slipped, or read carefully. . .

Pro is the 20th has a long forum topic [flame! ! ! ] All we wanted but were afraid to say an equivalent luminosity.

15.06.2009 8:49:00

this is nonsense and heresy!
no equivalent f-number does not exist!
is the equivalent depth of field achievable at different f-number of the photographic material in different sizes

15.06.2009 9:42:00

However, many do not know that it is equivalent to the minimum aperture value also changes - is transformed into 1, 4 (F) * 1, 6 (crop factor) = F / 2, 24!

It only means that in order to get sprinkled same DOF as on FF, it is necessary to set the aperture value, divided by 1. 6.

15.06.2009 9:55:00
however, if you want to get more grip on FF than sprinkled, nobody Well do not say that is the equivalent of FF, but then again multiplied by 1, 6
ie FF when shooting landscapes or macro instead of 8 (on CROP) should be put 14! All FF - garbage, aperture equivalent darker - fuuu
nonsense?

15.06.2009 9:59:00
Attention!

One topic [flame! ! ! ] All we wanted but were afraid to say an equivalent luminosity. in the 20th forum is already there. Litter remaining the same is not necessary. Recalls 3. 4. 7. deviation from the topic discussion (offtopic).

What about cleaning - there are like, rather big branch - certainly something sensible to have
Image Sensor Cleaning and focusing screen DSLR

15.06.2009 12:38:00

look, please, in private threads

15.06.2009 13:26:00
Cleaning marritsy, foremast. screen - it is certainly often write,

but than clean from dust eye VI? removing the cover, of course, you can clean it with cotton and rags, but my heart feels that plastic eyepiece there is very gentle.

note that pear is not clean. dust remains on the glass.

15.06.2009 13:37:00

but than clean from dust eye VI?
wand for cleaning ears normally works

15.06.2009 13:39:00

than clean from dust eye VI?
I think any brush (from lenspen "a or art, Squirrel) suit, you can still something of napkins PEC" A "PAD + build a toothpick or something like that
I have it just a little dusty, but it does not look interfere, not even noticeable (analogy with the front lens and dust on it) main finger back and you do not accidentally get into, then just have to grease stain smear

15.06.2009 14:05:00
cotton wool to match and forward
well, not much rubbing of course, but just dust shoot
if easily relate to, the villi will not go
and ear too hard

15.06.2009 17:12:00

15.06.2009 17:20:00
Does anyone know whether to save the 450D somewhere in the EXIF ​​information about the shooting distance?
Or it depends on the lens?

15.06.2009 17:25:00

lens with this capability - saves

15.06.2009 18:01:00

lens with this capability - saves

Thank you. I
EF-S 55-250MM f4-5. 6 IS. So I'm in the EXIF ​​this distance is not found, although here: http: // canon. ru / products / specification. asp? id = 2166 written that distance sohranayaet.
This is me bad looking or are they something else mean?
 

15.06.2009 18:26:00
quote:
: or are they something else mean?
lens that supports flash metering E-TTL II, must transmit information to the camera focusing distance. Is it written in the EXIF, another question. By not having a lens relationship.

The specification on the lens said:

Information about the distances: yes

this means it will work E-TTL II (and perhaps this information is used by other algorithms camera).

15.06.2009 20:53:00
Strangely enough, looked exiftool "om - does not show the distance (55-250)
but what else was looking and shows...
although exiftool gives full information, so that the second prog nonsense what that showed...

15.06.2009 21:08:00


Thank
Yes, apparently, in this EXIF ​​information is not available.


rather than watching others and shows. . .

than others?

Can this program showed no nonsense.


16.06.2009 0:01:00

So here I am a little podvis when all read it. How would it turns out that from Kropa it darkens. Lan went to the link and read.

16.06.2009 0:19:00

nothing gets dark!
meant that the depth of field will be the same (and noise) with a lens on FF and sprinkled by multiplying the aperture on sprinkled on the crop factor and put the resulting number by the FF camera
in principle, + - this is so (not always about osobonno noise)
luminosity but it has nothing to do

16.06.2009 0:26:00

meant that the depth of field will be the same (and noise)
Well, there is clearly excessive noise.

16.06.2009 0:29:00
Well, after reading the article, I have the impression that the dark.
came in from the link - there is generally a blade Baska, I'm stupid, not master.
And this - offtopic.
punish.

16.06.2009 5:10:00

Yes, apparently, in the EXIF ​​this information is not

information there!
in dpp if you begin to correct the distortion / vinetirovanie, there is a slider range. it is not in meters, and just dial 0-infinity. but still have this information in a file.
and how do you see it in ekzife? in meters? it depends on the focal. I think in ekzife it is not considered, and it is stored in a position of the focus ring on the lens. While it may be wrong, but it was another question - whether stored. I told him

16.06.2009 8:11:00

and how do you see it in ekzife? in meters?
course, the outbreak of this information is transmitted in these values

16.06.2009 9:03:00

and I'll say only about noises and sometimes
but supporters Afanasenkova honestly believe noises and shiso
forum it went - there is horror, let me tell you what that admiration, and he takes for granted (and teaches)!


so there is a ekzife in meters or not?
to some prog I saw
and exiftool does not show


16.06.2009 9:19:00
I think that it is not ekzife in meters, but then converted to flash (or most flash recalculated) taking into account the focal length.
not primarily because the distance and the position of the focus otnostitelno FR.
in general, if the number of distance would lie in an explicit form, DPP would write it, and only shows the distance scale.

and in general, what to know how many meters has been the focus? if it is so easy to learn, then check back on the front-focus can be carried out purely geometrically. removed a ruler to measure the distance to the target, then look in ekzif and comparing the actual distance from danymi on ekzifu know - who is to blame for back-front focus. if ekziv is the real distance - blame the lens if ekzife wrong value - blame carcass, t. To. Measure the distance wrong.

but not so simple. or so?

16.06.2009 9:34:00

certainly not as simple lens measures the distance from the low accuracy
there simply applied conductive path with perforation (mechanical analog-to-digital converter at once), and it runs the slider is in a variable resistor

16.06.2009 10:33:00
Information about the distances clearly prishetsya, t. To. In later used in the DPP.
accuracy of this information - plus or minus two locomotives, the accuracy drops dramatically with distance.
IMHO why not show that users do not change the ruler and then did not complain to the service:
Ahh. . I was photographing birds for 200m, and focused on the lens of 5m (hyperfocal distance), that for horror, what a dreadful front focus. . .

16.06.2009 14:12:00
how to determine the supply of white or gray? and how potestit camera when buying on bekfokus etc? . what to check when buying?

16.06.2009 14:38:00
white machine has a valid warranty card, called the 450d and not rebel or kiss

10 digits in the serial?

16.06.2009 20:36:00

yes

16.06.2009 22:02:00
http: // pleer. ru / _19935. html? ya advise you to pay attention. Today accidentally bought a photo. py - more expensive there. It's a shame! Do not fall for provocation! cool thing - I recommend! Although not the original, but much cheaper!

16.06.2009 22:06:00

shame!
on ebay you better not look - instead of resentment is strong disorder.

16.06.2009 22:14:00
already looked - somewhere $ 70? yes i do? and always want to hurry. . .

16.06.2009 22:26:00
$ 70 with two batteries batblok sell. China to send me a few days reach

16.06.2009 22:49:00

Sorry, there are no suitable cards and Maestro did not seem to fit but it would also purchased.
And another question to all colleagues who have Canon EF 50/1. 8, how it behaves on the 450D? I would like to see examples of photos. And the same question about the design: it "fifty dollars" is the same tube as the whale is put forward (I mean the front lens, spinning + advances)? And with what he aperture sharp (sharper whale on f7) ? I think whether it is worth thinking about 50/1. 4?

16.06.2009 23:25:00


question to all colleagues who have Canon EF 50/1. 8, how it behaves on the 450D? Yes
perfectly behaves much better for portraits whale. I generally only kit for wide-angle and / or in dark places (stub) left.

front lens, spinning + extends
nominated and not cool.

And with what he aperture harsh
IMHO, with 2. 0 is already quite sharp. 1. On 8 as mentioned above, mylnovat. Sorry, there are no examples.
 

16.06.2009 23:32:00

I have in the gallery where FR = 50mm and is said separately that Takumra - is with him.

http: // omploader. org / vMXUxag
http: // omploader. org / vMXU2NA
http: // omploader. org / vMXU1dg
http: // omploader. org / vMXU1ZA
more links to it. In principle, the exif "e parameters have.

Will the extra money - buy yourself 50/1. 4, but when it will be extra money In principle, only the errors of focus and inability to focus fine-tuning without the clicking of a lever to MF him less. ..
