DSLR cameras write to an internal buffer before they write to SD Card the buffer size and the quality determines how long they can sustain the full FPS shooting speed, my 80D can do 10fps but only for a small time at full RAW. More expensive cameras have bigger buffers and then things like the Nikon D500 have 2 card systems for ludicrous buffering to a very fast card for sustained high FPS.

However 1 1/3 shot per second should be pretty easy, the issue might be that the camera is exposing for 1/3rd of the interval but it has 2/3 of a second to empty the buffer so should be fine.

I use this app https://dslrdashboard.info/introduction/ to control my camera (I use the Android version in the field for focus stacking macro) you can configure the camera and set a time lapse whether it works for your camera is unclear 1200D is supported so I can't see why it wouldn't.

Some remote software introduce delays into the intervals to avoid locking the camera as remote controlling can be unreliable, you can configure this in the software usually.

I'll test my 80D over wireless using QDSLR today see if I can get 1 exposure a second.

I tried my 80D using QDSLR over wifi 10 frames with 1 sec separation did not work it started okay but after 3 frames the delays became inconsistent and it ended too soon

10 frames with 2 seconds separation worked fine, the shutter speed didn't seem to matter.

I feel the limit here is the remote control interface just being a bit poo poo when you try and do things quickly.

No, probably not mounting the speedlight on camera. I was considering 2x AD200Pros, but if the TT685 and AD200Pro produce two very different types of light (and I feel like they would) maybe two AD200s is the way to go.

The light the AD200 produces is really down to the head you put on.

I always assumed that it's because the ergonomics of macro lens design prioritizes close-distance shooting (as opposed to being a design tradeoff between internal-focus lenses and trombone-style ones).

To provide a similar amount of focus throw for longer distances the macro end of things would require a lot more cranking at closer working distances. For small subjects you'd most likely be using the focus ring on your macro lens to set your working distance (and hence magnification), and rocking back and forth to nail critical focus.

At regular subject distances the focus ring is more useful for... uh, focusing, but I guess the lens designers figure you'd rather be using your macro lens for bugs or flowers or whatever.

e: Another factor could be because the amount of lens element movement required gets much larger the closer you're trying to focus. Internal focus macros are often a much shorter focal length at their closest focus - for instance, Sigma's 180mm macro has a focal length of 100mm at 1:1. It's not all bad though, since you still get more close-up working distance than you expect because your front element doesn't have to be shifted forward the way a trombone-style macro is.

My Canon macro has 3 focus limiter settings full range, limit focus travel to macro ranges and then one for over macro ranges using the right limit settings helps with focus speed at that distance.

Anyone rented an expensive lens? I called up a rental company here in the UK for a 600mm f/4 Canon IS II (yeah) for 1 week.

Is it common to ask for the total value of the lens to be transferred to the company for the duration of the rental?

Also I would have to add it to my insurance for destruction/theft.

They want £300+vat and charges and delivery.

It appears that they'd charge you about $360 in total (plus the delivery, tax and insurance) for a week of use with that lens so the UK company seems to be legit too though I don't know why they expect you to give them the entire value of the lens for the duration but perhaps because they don't offer insurance of their own like Lensrental does?

Yeah so essentially I'd have to give them the value of the lens and then if something happened to it they'd take that money and then i'd have to negotiate with my own insurance who might value the lens differently and might give me the lens which I don't want to buy at that price want rather than the cash value of the lens back.

edit:
I just rang these guys and it is much simpler, insurance is included, slightly pricer but all up front costs.

I'm pretty cynical, some photographers want people to imagine that their photos congeal from their personal pure talent and involve no technical side at all and as such are not very keen to talk shop lest it give people a view behind the curtain.

Ultimately despite Instagram, Facebook etc you have to take photos for yourself (unless you get paid for them obvs) because outside of a few nerds who take similar images other people (especially other photographers) are generally not that interested in your photographs.

However I do devour other photographer's work and always want more of it. But it's less about feeding the social media engine and is more about studying the images I like and trying to incorporate the techniques I find into my own shots because learning picture taking in a vacuum is a giant waste of time.

This is just a question I've had floating around in my head for a few years - how come macro lenses tend to be pretty cheap compared to normal top-tier lens like a 50mm f/1.2?

Most macros are f/2.8 wide open you pay alot for f/1.2

A lot of macros have manual focus because you don't really need AF for macro when you are generally using a flash and focussing by moving the camera, some even have manual aperture control (much harder to use.)

The Canon 100mm L macro is 1x has IS and AF and is f/2.8 it's a bit cheaper than the f/1.2L and the f/1.4 50mm Canon is half its price so you're paying for that wide open aperture with good optical quality.

Macros don't need to be so wide open as most of the time they are not going to be that open because the DOF will be a razor at macro distances.

Hi, thread. A couple years ago I bought a Canon Rebel T3i before I went on vacation. I took some really nice pictures but I know deep down I'm not using this camera to its potential and have some casual interest in getting more out of it. I'm interested in macro photography because I want to take pictures of aquarium fish, corals, and watches. I know the glass and water add quite a bit of complexity so I'll probably start with watches.

2 Questions:
What would be a good resource for learning beginner level DSLR photography?

What would I need to buy to take better pictures of small things?

For nature stuff you generally want ~100mm for reach so you are not disturbing the subject, you can get 60mm or 35mm for studio stuff where you are in full control, no hard or fast rules here though people use many focal lengths for all types of macro it's a personal thing.

After the lens macro is about lighting and/or stacking, your depth of field is very narrow when shooting very close so you will want to close down the lens to increase this for single exposures or stack by taking multiple exposures and moving the focus point or subject/camera each time. People do both for really, really close up stuff or for maximum quality when in a studio.

If you are limited to a single frame (most nature macro of live active stuff) you need a flash for two reasons one because you are shooting such a closed down aperture (f/11-13) for acceptable depth of field you need extra light and two because when something is magnified your IQ is greatly affected by camera shake so the flash pulse freezes out the camera motion.

You will find that a lot of the best macro (especially of live insects) is taken by people who are pushing optics/cameras/lighting to the limits often with very frankenstein setups that are custom built, there are off the shelf type solutions but even these have limits/draw backs and most macro photographers are using some sort of custom setup largely based around getting as much diffused light as they can on subject as quickly as possible.

In the studio most are stacking using automated rails and software to control the camera/rail i'd recommend stacking for watches (just be sure to stop the action 1st so the handles are not moving mid shot.)

We have a macro thread here in the Dorkroom so feel free to ask some more questions there.

He doesn't have much of an online presence (just an instagram account) but I find the setup for the macro dude in this video to be super interesting:

https://www.youtube.com/watch?v=Oj_mWGgrvr8&t=87s

Yeah that's the general idea that most people are using, it gets harder when you are doing greater than 1x APS-C/FF on really small stuff with light fall off and bellows factor meaning your flash isn't firing fast enough to freeze out the hand motion.

Those smaller mirrorless and m4/3 camera actually really help with light because the flash is closer to the subject because the whole setup other than the flash is smaller, that guy's not quite shooting at the magnification/resolution that I like to try and get but I have to use a larger DSLR, there's tradeoffs everywhere with macro.

Also some insects are spooked by the large white diffuser and the light can be too flat if you like more a contrasty feel to your images so it's all a trade off with regards to light quality/speed/practicality.

Is that a stack or one shot? If one, how do you get your DOF so wide?

That's one frame with flash, the depth of field is still narrow at f/11 probably only ~1 mm with the hoverfly being maybe 2.5mm wide at the head so maybe 50% in focal plane but the real skill of macro is in making best use of the narrow depth of field with your composition (and a large slice of trial and error/luck)

This photo isn't even a good example of that concept, this butterfly is taken without flash at f/5.6 (it's a bigger insect so further away ~37cm from sensor according to EXIF as this was taken with an AF lens, where as the hoverfly was taken with fixed focus lens) but no flash so narrow DoF but by getting the proboscis and eyes in focus by slanting the angle I can make the best of the DoF.

Lightroom has an option where it wont show full quality even in develop mode unless you disable it, things can look very different, Check your "develop" settings under the performance tab in preferences.

You can also set 1:1 previews for the library mode.

Basically there's all sorts of things going on under the hood to improve performance by sacrificing IQ in previews and other places apart from final output. If you have a moderately powerful computer and are not messing with thousands and thousand of RAWs you can usually turn them off if you like seeing full quality all the time.
