That photo is sharp Amin you can still enhance it a bit but if you don't crop it at 100% it's more then good.
If you want to fill the frame more with the bird just take some step towards it, you haven't got those legs for nothing

When you set your flash on trailing curtain your camera will meter like normall but also use the flash to freeze the action at a point, it might do the trick as fill flash but I've never tried it.

Like the title said my first try so please don't be afraid to give some good comment, I've still a lot to learn and any help or suggestion is welcome

The photo was taken yesterday when we went on a hike to Hook of Holland.
Landscapes really aren't my thing but the sky was just beautiful so couldn't resist to take some snaps ^^

Nice photos and very sharp!

There are many topics about the matter DA* 300 + TC vs the Sigma 50-500 or 150-500 and most agreed that you will have the best quality image with the DA* 300 plus TC or with just cropping, just to answer your question.

Like gwyn said you need to learn how to use it, the diffrence between 300mm or 500mm doesn't look so much if you compare them link

This is one of my bird shots with the 18-250 on the long end, as you can see a long exposure time but the tripod make the diffrence here and it's cropped quite heavely. a tripod would be to heavy to run with but a carbon monopod would be the best solution for this. I bough a monopod recently but I still need to field-test it on birds though
Got some long exposure of a second when doing infrared photography, also still need to check how they are

Also postprocess your image, you saw with the gull in another topic how much sharper we could get it.

Nice shots Karl, I really like them.

There are many ways how to process them and it's just what your taste is or what you want to do with the photo.

I was so free to use one of your photos as an example if you've a problem with that I'll delete it okay.



Mainly Played with the curves but there is also a tweaked darken layer to get the detials and colour of the lower half back. I might have overdone it a bit but it's just to give you an idea.

I love those sunsets Amin, certainly the one with the bird, maybe you can crop that a bit to get the bird more in the frame to make it more interesting.
The other photos are nice but just a bit boring to be frank
I always find it hard to photograph something interesting when doing landscapes so it isn't just you

For the photo you asked to chose, I'll pick the first one since there isn't much happening in the foreground.
This a good, fun read about composition that will do you good link
Here are some off his photos if you have some time link they are pleasant to look at

Nice shots Amin,
I will give you a little tool for your photoshop that will do a nice job to sharpen those photos.

To at something what Cliff said.
I know you've a tripod and a RF remote so set the camera up in the garden close to the table. I suggest you use the D-FA 100mm it's the sharpest lens that you have, you will make some cracking photos with a bit of luck.

Yorian,
Don't worry so much about the glass they can take a lot, you must be carefull that nothing comes into the camera so point the camera down with the opening to the ground when changing a lens. Also choose a good spot (place) to change a lens and if you are a lot on the beach try not to change a lens at all or do it in your camera bag, it needs some practice to do that fast though.

To clean your lens get some of those dry cloths from specsavers or hands-anders that you use for you glasses they will work fine for your lens as well and get something to clean your sensor it will get dirty with dust for sure. I used to use a blower to clean the sensor but that blows all the dust just to another place so I bought an artic-butterfly and that works quite well and you brush the dust off from the sensor instead of blowing it to mirror and the viewfinder

No it was a mistake don't worry.
