[jeremyisaaclee]

Do any of you currently have the Canon EF-S 55-250 IS? Would like to hear some reviews, and where you got them. Thanks. :)

Anyone know the street price of this lens in Penang?

[julchin_09]

If I remember correctly, a friend of mine enquired about this len which was just released by Canon. At a price of RM950...

[g88]

price is between RM950-1050 depend on dealer....available in MY ?

[julchin_09]

My dealer at Lowyatt told me about a month back that he's taking in goods. But when I wanted to get one for a friend, told me the stock hasn't arrived. I haven't enquired since.

I see on the front of the lens, there is a rubber ring to rotate (not zoom). Is that a focus ring?

Anyone knows whether this lens has internal focusing? How can we tell whether it has on Canon lenses?

RM860 at Foto President - Queensbay Mall (need to order from Canon Malaysia)

The larger ring is for the zoom where the smaller is the focussing ring. It has big focus ring but it doesn't allow full-time manual focusing.

This lens doesn't come with internal focusing. Lenses that apply the technology will not extend during focus. For example, ALL canon L lenses apply internal focusing as they do not extend during focusing.

Thanks mki88.

Any idea how can we tell whether the lens has internal focussing or not? Are there any non-L lens that has internal focusing?

The reason why I ask is because attaching a polarizer on lens which has internal focusing will be more effective and convenient as one doesn't need to rotate everytime a focus change.

Er that's not technically true. Internal focusing means the barrel doesn't extend in and out when you focus, it doesn't mean it won't rotate.

You can have non-IF lens with non-rotating front element and IF lenses that do rotate the front element when focusing.

Thanks ST for correcting.

What i meant was non-rotating front element.

How can we tell from the lens spec/label without seeing the physical lens?

From the lens spec, u can't really tell that the lens has non-rotating front element or not. Canon has not put this in their lens spec. The best way to do so is to google the lens. Then u can know that does it rotate during focusing.

ST, I thought lenses with IF will not rotate during focusing? :? Any example which lens has IF feature but still rotating during focusing? :? :?

[forger]

any comment in the peroformance?
caompareableto maybe a sigma 18-200 os dc

[naliazor]

the cheapest in spore is around SGD380....

Correction on that ST.

"An internal focus lens (sometimes known as IF) is a photographic lens design in which focus is shifted by moving the inner lens group or groups only, without any rotation or shifting of the front lens element. This makes it easy to use, for example, a screwed-in polarizing filter or a petal shaped lens hood. During macro photography, using an internal focus lens reduces the risk of the front of the lens accidentally hitting the subject during focusing as the front element does not move."

Flash demo on how IF vs. Conventional lens work: http://www.canon.com/bctv/faq/if.html

[ShaolinTiger]

IF just means internal focusing, no more, no less. It doesn't necessarily mean very much about whether or not the filter threads rotate. The filter threads of an IF lens probably don't rotate when focusing, but may when zooming. There are lots of non-IF lenses that have fixed filter threads that never rotate.
IF is used in non-zoom lenses (mostly telephotos), and when it is used, it is called out. The manual focus 300mm f4.5, for example, comes in ED-IF, ED (non-IF), and plain (non-ED, non-IF) versions. At one point, all three flavors were available new in Nikon's catalog at once. In today's autofocus "D" lenses, you can get an 85mm in a f/1.4 IF version or a f/1.8 non-IF version.

Verdict

Technically the Canon EF-S 55-250mm f/4-5.6 IS is a tiny lens with a great performance potential. The resolution is very good across the range. Chromatic aberrations are basically a non-issue. The level of distortions remain moderate. The most obvious flaw is, unsurprisingly, vignetting at large apertures. The build quality is fine for a lens in this class and it is one step up from the EF-S 18-55mm f/3.5-5.6 IS that we've seen here recently. Regarding the target market you may surely forgive the plastic mount. The AF (micro-) motor is pretty fast and silent. So's everything cool here ? Well, the AF accuracy didn't really convince in the field - specifically at the wide-end of the zoom range - but to be fair this may be better on an EOS 40D (e.g.) with its improved AF capabilities. I had some trouble with the image stabilizer in the field but according to early reader feedback this impression seems to be an exception to the rule. If so the EF-S 55-200mm f/4-5.6 IS has certainly the potential to be another hot seller.
