Do you have sample pics to show when this happened? How far is your object to the camera? Besides being too dark, perhaps the object you're shooting is too close for the 18-200.

The 24-105 is a Canon isn't it?

24-105mm sigma art

if you zoom , aperture become smaller so it will be more difficult to focus

btw you can try change auto focus to Release On

interesting, nigerian scam now using asian sounding names to scam around this area.
got one email from a 'kelvin chong' asking to buy one of my lenses...then next email says hes in UK...wants to buy as gift for grandson blah blah...asks to post...and thinks ppl stupid

Just finished setting up my new macro kit, with flash of course but not included in the picture haha. Quite satisfied with it considering I have around 15-20cm of working distance left even with 3 extension tubes added at closest focusing distance



Sample pics taken in the night just now, something new for me to try grabbing focus in almost total darkness but as most of the bugs are chilling and resting they gave me a lot of time to slowly focus.

always the same story...

Nice one
Extension tubes, even Kenko ones, are not sturdy enough for a heavy lens, the 12, 20mm ones will always spoil first (losing contact with the body and getting F0), followed lastly by the 36mm T____T Its best to invest in a Raynox 150 or 250 instead, depending on what you are shooting

I started off with 3 ET too, but getting the highest magnification in a macro shot is not always the key since the DOF becomes too shallow

Night macro is fun, most people attach a guide-light (powerful flashlight or just a simple headlight) on top of the lens to allow you to focus better Let's go night macro sometime~

Thanks

Hmm the Sigma is quite heavy but OK for the extension tubes I think, have to handle with care though since there's so many mounts at the same time. The fun part is even when you focus to infinity you are still getting around 1:2 or bigger magnification with extension tubes.

Yeap that's the problem, I shoot around f16-f20 depends on the size of the insect, luckily my flash strong enough to light them up.

Definitely necessary to have such equipment, I tried using the AF illuminator on the d7000 yesterday but too bad it only works in AF mode. I going back to Kampar this weekend or something, lets go haha.

I have a lighter lens than yours and I have already used up my 2nd pair of Kenko tubes, its not worth the money spent Will let you try out the Raynox 150 and 250 next time and you will get what I mean

I'm going down to KL this weekend haha, can't make it.. we will until semester starts ba haha
Until then, keep practising

Stop poisoning others la. Adui~

Hahaha mana ada bro?
That was actually very good advice, the macro sifus never mentioned this and I wasted ~RM1100 on Kenko Extension tubes which will eventually spoil due to lose connection

Signal Fly by Ji Tan, on Flickr

Had to literally get into a dustbin for this shot

Signal flies are easy to identify due to their colourful and bizarre eyes which come with "wavy " patterns.

These flies are attracted to plant material or decomposing organic matter.

Six-spotted Scorpion Jumper- Bavia sexpunctata ♀ by Ji Tan, on Flickr

This Salticid is so called because of the obvious 6 spots on its abdomen, and also the fact that it looks like a scorpion while resting.

These spiders are often found on buildings or on tree trunks. The first pair of legs are strong and well-suited for hunting.

U kaya xpa lor.

Butter and kaya

aiyah too bad then

Luckily i got mine (meike ones) for quite cheap so even if it spoils it doesn't hurt to much (of course if it doesn't then that's best). Sent my camera to Mutiara complex to clean sensor few days ago and just realized the old spots are gone but there were some new spots also, so frustrating

Anyways fresh pictures.

Hi, my relative gave me his Nikon D80 coz he didn't use it for a long time already. But there are some problems with the camera like the shutter release button won't take a picture when it is at Auto Focus and at some different modes, pictures taken are just black. Anyone heard of these issues before? I plan to take it for repair but just scared it costs a bomb.

I'm totally a newbie in photography, this is the first DSLR I have ever used. I'm not even familiar with normal digital cameras, only own a passed down Lumix LX5 lol

Want to start learning with old cameras first before I can even think of upgrading.
