Guys anybody using the baby beercan? Is it a good lense to replace the kitlense?

nope.

i'd buy even its 6k+...even a 2470 cost 5.5k already =p

but agaiin...it has to be a ff lens.. =p

dont think so , u'll loss the range
and perhap u want to consider newer lens
minolta is cheap but its old and got no more warranty

got the Sony CZ 16-35mm f/2.8 edi what ..

2470+uwa lol thats around 4k! haha
2470 HSM is almost 4k ler, If i were to buy that, i rather save a few more months to get cz2470 haha
but thats too far to reach.

albert got 1770?
actually gear strip will only occur when u put the lens in MF and the body in AF right? or am i wrong?
need to call kysham to test his 2470 again!
lets organise a tt to test out kit lens replacement

Hi, where can find minolta 50mm f1.4 in KL ?

Thanks guys !!!

achew: Yes, any USB to Micro B should work. Mini B is a different plug.

croomaniac: I never ever had a Sigma 17-70mm F2.8-4.5 EX DC. I had a Sigma 17-35mm F2.8-4 EX non-DG which had its gears stripped.

tanjq87: There are many theories to why gear stripping happens - temperature, oil, mishandling of the AF/MF clutch. However my 17-35mm was internal focus and had no clutch (like a classic Minolta lens). Also, some lenses are just very prone to it, while some have never experienced it. I just take it to cheap plastic used in the geartrain and gear ratios that can exert wear/tear on the geartrain.

For the record, I have only ever owned one APS-C lens - the Sony 18-70mm F3.5-5.6 DT. After selling my A100 + kit lens, I got the Sigma 17-35mm which is a full-frame ultra wide angle.

Guys,

For all those using APS-C sensor you would need to seriously re-think the 24-70mm range. It is not nearly wide enough on the wide end. 24mm in FF equates to 36mm in APS-C. The angle of view is almost like a 50mm in FF. Although you would still find some uses to it you will have difficulty in trying to get large group (i.e. more than 3 persons in a row) to fit in when you are in cramped quarters.

The 70mm on the tele end is not tele enough for decent runway coverage when shooting models. You guys with 18-70mm should know how it feels like.

I dunno about you guys but the 24-70mm range is severely limited by the APS-C sensor. You get an expensive lens that is neither here nor there. For landscapes it not wide at all. For events is it just outside the usable wide range and for runways it's not long enough! Frustrations all around. Most practical is to use for portraits but given the price I would rather go for the 50mm F1.4

If you have the money you would be better served with a 16-35mm for the APS-C

That's the reason the 17-50mm F2.8 is such a popular choice among APS-C users.

P.S. Albnok has the 17-35mm sigma and had experienced stripped gears with that lens.

tan & albert: yeah, now i can register that.. it is 1735, not 1770..

oh, so better don't get the lens that are prone to gear stripping. I always thought it's only mishandling of the AF/MF clutch.
Do cz1680, sal16105 and sigma 1770 have the MF overwrite mechanism? So far I know tamron 1750 has no such mechanism.

36mm and 50mm is still very different la..
maybe i should tape my 1870 to 24 and walkaround
but true la, one of the most important question i always ask myself.
"Can I live with the widest 24mm?" "Would I regret after getting 2470?"
I guess you answered my questions.
Yes I think I will regret unless I get another ultra wide angle.

Only the Sigma 24-70mm EX DG Macro has the AF/MF clutch.

The Sigma 24-70mm F2.8 EX DG HSM and Sony Carl Zeiss 24-70mm F2.8 SSM both have AF/MF switches and MF override.

All Sony lenses with an internal focus indicator window (except the Sony 50mm F1.4) have a focus clutch, which means the focus ring does not rotate when auto-focusing.

Bear in mind also that any 24-70mm F2.8 will be very big and heavy.

oh.
Do you know how's the performance/image quality of the sigma 2470 Macro? I don't mind the size if the quality is good.

The Sigma 24-70mm F2.8 EX DG Macro is sharp but chunky. And quite prone to gear stripping.

The Sigma 24-70mm F2.8 EX DG HSM however is rated to be superb optically. And because it has its own focus motor inside, it will not get gear stripping.

If let say gear stripped, send for warranty, would it be still prone to gear stripping?

but HSM version is double the price

am confused on tamron 1750 made in japan and china. how to identify it?

albnok, what will be the major advantage of tamron 1750 compared to kit lens 1870? thank you.

hahaha... sorry bro... not much time to go out shooting these days... wanna spend time with my baby girl and wife at the moment... lagipun... masih berpantang... hehehe... only by the 8th then can be a bit free...

Aperture wise,
1750 has constant widest aperture throughout the focal range which is f2.8.
1870 widest aperture changes (from f3.5-5.6) as you zoom.

Sharpness wise,
1750 is much sharper than 1870.

Build wise,
1750 should be much better built than 1870.

Flare wise,
1750 has a proper hood to reduce flare but 1870 hood is a joke.

go for HSM - leaves you worry free of gear stripping..

me not albert, but tamron 1750 is a fix aperture of 2.8.. and it is said sharp wide open
