Well I took the plunge and brought the Sigma 70-200mm f2.8. Reading reviews, comparisons and getting lots of recommendations from friends/family, I figured for the money it's hard to miss. The only other lens I was considering was the Canon 70-200 f4 since they're in the same price range. The extra f stop is hard to pass up.

It's a little heavy from what I'm use to, but I don't think it's that much heavier like some people are complaining about.

I also picked up a 1.4x TC with it too so this should prove interesting.

I buy my gear from d-d photographics. The lens are "grey import" and sure it's a little more expensive than ordering from HK/cheaper buying locally but atleast I don't have to worry about shipping issues/getting hit by tax etc.... warranty though is another story. :D

Well, compared to my previous telezoom (Sigma 28-300mm f2.8-6.3) it sh*ts all over it! I brought that lens because at the time I was on a budget and needed something before I went on holidays.

It's been raining in Sydney so I haven't had any real chance to take any real pics but so far it's promising. It's better in every way compared to the first lens and the EFS 17-85mm lens I've got, but I haven't really compared it to the my prime 50mm f1.8.

I'm hoping Sunday/Monday it's clear so I can wonder around Sydney for some happy snaps!

Ewww .. the 28-300mm is a SHOCKER !!! I think it's one of Sigma's worst lens. Although they did redeemed themselves with the 70-300mm APO DG.

Likewise, I was considering the Canon 70-200 F4 at one stage, but the extra F stop is hard to beat. Although a 70-200 EX APO DG with OS would have been PERFECT !!! :)

Let me know how your Sigma 1.4x TC perform with the 70-200. I wonder if the 70-200 + x 1.4 TC is much better than the 70-300mm APO DG ?

It's beyond shocking! like someone said in their review, it'll turn a DSLR into an ordinary point and shoot camera! lol!

I'll let you guys know. Any ideas on how to test the lens with and without the TC? I'd like to show you all.

Try using the newspaper test at 1.5m, stick a piece on the wall and shoot the Sigma (without TC) at 200m F4 and then again at ~140mm + 1.4TC. Crop the center at 100% and have a look at the sharpness of the fonts to see the diff.

I'll do the same and show the diff between the Sigma 70-300 vs Sigma 70-200.

I'd be more interested to gauge it's autofocus performance - you buy long lenses for action photography - motorsport, birds/animals etc. - stuff where getting the picture in focus is more important that the extra stop of light.

thats the reason i got the canon 70-200 over the sigma, it focuses faster

although i've nevre tried out a sigma, so i cant really comment

Hmm I think I have received a dud Sigma 70-200mm EX APO DG. I did some test shots and posted here.

Look as though I have to send it in for calibration :) Or even a replacement copy.

Be good to see the pic comparison ;)

lol

As a comment on concerning the camera purchase, I'm going to get the camera from JB hi fi locally. Just wondering what size memory card you guys suggest/have. Is a 1Gb card more then plenty enough space?? Ill haggle them enough so they'll throw in a free card hopefully ;)

a 1gb card should hold around 260 photos in Large, and around 115 RAW on a 350d

so it just depends on how many photos you plan to take in one day without emptying the card

don't buy cards larger than around 2-4gb,

i'd rather have 2x 2gb cards, than 1x 4gb card, if the card fails, you've lost a lot of data, so its better to have it spread across more cards

Yeah I'd also prefer to have a few cards instead of one big one. If your planing on doing fast photography (eg, motorsport) make sure you get a fast memory card too.

simplelogik, I conducted the tests in the same manner as you and had the same results. I also noticed that it had rather poor AF in low light situations. And I found out that other owners had the same problem. When I got more time I'll conduct the same test with more light.

In the mean time I took the camera out and took some happy snaps. The pelican pics turned out alright. But the other pics I took, I was stupid and forgot to change the ISO. So the other pics do have a bit of graining because of the ISO400 setting. :) It's the first 4 pics in my SAU gallery and the EXIF details are in the comments box.

Thanks for your input. I'm going to try and get it looked at here in Oz, if not I'm going to send it back to HK.

Even the seller agreed that it was too soft. I bought it for indoor shooting, so it needs to perform at F2.8. I found that at F8, it perform the same as my 70-300, so there’s no advantage in shooting at that aperture.

In regards to noise, have you looked at Noise Ninja ?? It’s fantastic for noise reduction!!! Even at ISO 1600 !!

    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
    • When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
    • So I found this: https://www.efihardware.com/temperature-sensor-voltage-calculator I didn't know what the pullup resistor is. So I thought if I used my table of known values I could estimate it by putting a value into the pullup resistor, and this should line up with the voltages I had measured. Eventually I got this table out of it by using 210ohms as the pullup resistor. 180C 0.232V - Predicted 175C 0.254V - Predicted 170C 0.278V - Predicted 165C 0.305V - Predicted 160C 0.336V - Predicted 155C 0.369V - Predicted 150C 0.407V - Predicted 145C 0.448V - Predicted 140C 0.494V - Predicted 135C 0.545V - Predicted 130C 0.603V - Predicted 125C 0.668V - Predicted 120C 0.740V - Predicted 115C 0.817V - Predicted 110C 0.914V - Predicted 105C 1.023V - Predicted 100C 1.15V 90C 1.42V - Predicted 85C 1.59V 80C 1.74V 75C 1.94V 70C 2.10V 65C 2.33V 60C 2.56V 58C 2.68V 57C 2.70V 56C 2.74V 55C 2.78V 54C 2.80V 50C 2.98V 49C 3.06V 47C 3.18V 45C 3.23V 43C 3.36V 40C 3.51V 37C 3.67V 35C 3.75V 30C 4.00V As before, the formula in HPTuners is here: https://www.hptuners.com/documentation/files/VCM-Scanner/Content/vcm_scanner/defining_a_transform.htm?Highlight=defining a transform Specifically: In my case I used 50C and 150C, given the sensor is supposedly for that. Input 1 = 2.98V Output 1 = 50C Input 2 = 0.407V Output 2 = 150C (0.407-2.98) / (150-50) -2.573/100 = -0.02573 2.98/-0.02573 + 47.045 = 50 So the corresponding formula should be: (Input / -0.02573) + 47.045 = Output.   If someone can confirm my math it'd be great. Supposedly you can pick any two pairs of the data to make this formula.
