Do periodically ask - " A what lens better?" or " A how this does differ from that?".Questions almost always concern several basic models.
On those, with which it was necessary to encounter/collide, and I will write.By itself only personal estimations/evaluations.Almost always rule " fur is more expensive - the better it is
" correctly, but is rarely not so/such obviously advantage of one over another.
"kit" lenss - this those, which go in the complete set with the cameras of initial and average/mean level.
canon EF28-80/3.5-5.6 and canon EF28-90/4-5.6, for example.The quality of picture in them in comparison with any other lenss of this producer
is very low.Strictly, they and the cheapest of zumov.From the hands of them it is possible to purchase on 50 and less than dollars in the ideal state - so many they request perhaps that for to
vusmert' that stirred by 50/1.8.After inexpensive soap-boxes or Soviet optic/optics it can seem by completely normal, and if you this quality satisfies by them completely it is possible to use,
but to buy specially on no account it is must.
Universal zooms of medium level - this is EF28-105/3.5-4.5 usm,
EF24-85/3.5-4.5 usm, EF28-135/3.5-5.6 IS usm .It is theoretically arranged/located by way of an improvement in quality and increase in the
price ( 170-210, 240-260, 490-530 USdollars at the current moment in the stores).All three lenss have the ultrasonic annular drive of auto-focus, which indicates rapid and quiet focusing.
All three - FTM (Full Time manual of focus), it is possible to turn the ring of focusing with the vklyuchenom auto-focus without the possibility to damage mechanism.
EF28-105 usm much better holds the light sources in the sequence in comparison with EF24-85 usm (if into the sequence falls something
bright, for example the sun - in the latter it will be the heap of specks of light), it was checked on one and the same chamber/camera, subject, and in the limits of one film. But with the open
diaphragm Of ef28-105 usm at the long end it is noticeably soft than EF24-85 usm . I think in its time this so it calculated by plus, since
this softness can be used with the portrait survey, and for the high sharpness it suffices to close diaphragm to f/8 this case EF24-85 usm
in entire porezche, at short end 24 in comparison with 28 - sometimes this is valuable, if you prefer to remove/take views, and not people.
EF28-135 IS usm besides an even larger sharpness of picture, than in EF24-85 usm , has a function of imidzhstabilizatsii
(letter IS in the designation) - upon its start the lens on half-press can for a while " retain " picture, in spite of small shifts or vibration of camera.After being fitted it is
possible to take on long endurances from the hands, some speak about the difference into 4-6 steps.In me with it are obtained two normal sequences from three to yeshchmm with endurance 1/4,
without it so it is obtained to 1/15.
There is another model Of ef28-135 usm - without the stabilizer. Sufficiently trying, has long ago been removed from production.At the long end soap.
From the hands it saw proposals in the limits of 100$.So there is 28-105 without usm - this is one of the representatives of kit
zooms.
My selection in this case, with the ogranichenykh means - EF28-105 usm .There are two modifications, 1 and II - the first now in the stores stand near 170$,
second 210. The second seemed only more rapid into the focusing, but this that is called " spinal cord I sense ", it did not check with the instruments. If money exist - is unambiguous
EF28-135 IS usm , only professional series is better it.
Telezoom - EF75-300/4-5.6, EF75-300/4-5.6 usm, EF100-300/4.5-5.6 usm,
EF75-300/4-5.6 IS usm.The first two nevazhnyogo qualities, and usm of there annular - it is possible to count false. EF100-300 usm
is already good. But with the purchase it is desirable to photograph test - fall too strong soft copies.With which this is connected/bonded - without the concept, but precisely this lens
is characterized by the sufficiently large difference between the copies. EF75-300 IS usm has another optical diagram, in spite of the same focal length
as in cheap EF75-300. Picture good, imidzhstabilizator substantially increases the percentage of good frames/personnel - for the large focal lengths the
stabilization is much more important than for the small.Minus - there are no FTM, front lens revolves.
it removed/took by these lenss not frequently.It somehow immediately seemed me that 300mm - this is sufficiently small for the surveys of the subjects, for which it was
necessary telees-vetch.Beasts scatter, birds fly away, people are scolded.V into the zoo, where the poultry to run out nowhere, I walk rarely.Tele-converter, which increases focal length
- not to place, candlepower at the long end of zuma already 5.6, this almost limit for the work of auto-focus.
Macro - my loved.Here already situation is complicated by the fact that cheap spetsializirovanykh makrolenses it does not
occur.Is certainly zooms from the strange producers like sigma with the word macro in the name - but this again not present of macro, and quality in this mode will be low. 50mm to macro-opticial
also examine I will not be - this is also a compromise, 1:2 scale will not enough be.
Thus - canon EF100/2.8 macro , EF100/2.8 macro USM , EF 180 macro .All three are splendid
on the optic/optics and the picture.The first is removed from production.The second replaced it, now it is focused rapidly.The third - outstanding, rapid, but is more than one-and-a-half
thousand dollars - this can spend not each to its hobby, especially because they buy it for the survey of insects, to which it is close not to approach, like the butterflies.On what of money
will be collected - that and to take, any other versions.
The lenses of the third producers - sigma 105/2.8 macro , sigma 180/3.5 EX IF HSM macro, 320$ и 740$ in the stores, this is
twice cheaper than cacon lens prices.Picture is good, in 105/2.8 konstrut it does not require blend, but it very slow in the focusing. Then it is not missmed, where canon
EF100 macro to vapor of times hither and thither drives. Old modification incorrect works on EOS 30 and 33. sigma 180 hsm is considerably
more rapid, outstanding picture - the nearest on the quality lens with respect to the the canon 180mm macro .
soligor - cheap, noisy, crackling, slow. To buy is possible only with the very modest budget.Front lens revolves, auto-focus is very loud.
Tamron AF 90/2.8 macro , Tokina AF 100/2.8 macro - opinions like not bad, but into the hands did not fall, nothing intelligible say I can
Telephoto lenses of the third producers - with a focal length of 400 and more than mm. Sigma 135-400 ,
sigma APO 50-500/4-6.3 EX RF HSM, tamron 200-400/5.6 , tokina 80-400/4.5-5.6 . From the mentioned lenss of sigma
it is good 135-400 (old modification incorrect works on EOS 30 and 33), sigma 50-500 a little bit worse (and even weight hearth two kg),
Tokina still a little bit worse, but has the smallest overall sizes. Tamron has only zoom with a fixed candlepower - 5.6 both on the short and at the long end. Moreover he has the smallest
range of buzzing, that theoretically also plus.
Smaller and cheaper models examine I will not in detail be, in my opinion there is no sense. Everything, who sometimes asked about cheap 75-300 either 70-200 - as a result nothing
they desired to hear about their low quality, about the fact that after adding 20-40 dollars it is possible to obtain something rather better, or at least the possibility of the selection
between several models, but bought as a result the cheapest with the words " well so this also 75-300 ".To such people are necessary not councils, but only very process of the giving
of clever questions.Nothing ask about 70-200/2.8 no one, the people in my opinion grown to similar glass already separately not whose councils require, so that to discuss them sense I do not
also see.
