I have the Canon 10-22 and find it to be an excellent choice. Sharp with very little flare and quick focusing.

Beyond that I don't know as that is what I do.


That and timing your shot to the top and bottom of the motion. Also, the heavier the camera the more inertia it has and the easier it is to stabilize.

If it is bright out then I am assuming you are using the flash as a fill light. If that is the case then the small aperture needed to correctly expose the ambient lighting will require a much greater flash output to balance it, hence the longer recycle time required between the flashes.

I don't know the exact flash sync speed of the D750 but it is probably around 1/200 s. When using high speed sync at say 1/1000 s only 1/5 of the sensor is exposed at any one time and the flash will have to fire at least five times in 1/200 of a second interval. Indoors the reflective surfaces allow it to fire at a reduced output reducing the recycling time. Outdoors requires more light and the capacitor will be depleted more quickly, greatly increasing the recycling time as compared to indoors and it simply may not be able to produce those multiple flashes in such rapid succession.

I've done the same--loved macro in the film days then got a career that left too little time for photography. Retired two weeks ago. As I have been converting to digital I look back at what I ended up with film and then have tried to replicate what I liked with modern alternatives that worked the same way. I avoided all the things that I tried and before and did not work for me. Enjoy!

Very nice. You have taken a style I generally do not like and created an image I like very much. I always appreciate someone who can open my eyes to something new. Thank-you.

The duration of the flash is very short, often less than 1/1000 of a second. The flash sync speed is the fastest shutter speed where the entire frame is exposed at one time. To get faster shutter speeds the shutter starts closing before it is completely open and a slit of open shutter moves across the frame. So if the sync speed is 1/200 s then at 1/1000 s only 1/5 of the frame is being exposed at a time and the flash would fire and expose only 1/5 of the frame, the rest would be underexposed. At 1/2000 s shutter duration only 1/10 of the frame is exposed at one time, etc.

Nature is the most complex, convoluted thing known, short of the human brain; but that is nature.

What's wrong is simplifying complex problems into memes. We all loose if we don't have intelligent conversations based on facts.

I have the Canon 10-22 which I like very much. Distortion is fairly low for such a wide zoom and flare is very minimal.

I got 245. To obtain the same field of view using the entire sensor area you would need a 300mm on the Pentax. Then cropping the image from the Pentax by 1.23 would give an effective focal length of 300/1.23 which is 245mm.

Both sets are excellent! I don't see the difference in depth of field. Some of the bees are at different angles and the primary focus is sometimes at the near side of the bee and sometimes in the middle. If the final magnification and aperture are the same the depth of field should be the same as well.

So what happens when a 28 year-old who chooses to skip getting insurance gets hit by lightning. Who pays for it? Why should I, or my insurance, pay? Do we let him die (not an option!)? Why not make him get insurance so that does not happen? Why not have everyone contribute to insurance and everyone get the benefits? The last would be the least expensive option for everyone over our lifetimes.

It's lens flare, a reflection of the sun off elements in the lens and would happen in any shooting mode.
