I have actually clarified the lens turnaround method previously. It is among the methods I such as as a result of the factors I discussed in the past. I have actually been obtaining a great deal of inquiries on reverse lens method since I released it. Given that it is coming to be a favored method of professional photographers, I believed I need to compose a lot more regarding it. I composed the short article by demonstrating how to turn around a 50 mm lens. However, it just provides you a 1:1 zoom. However, what happens if you desire a magnifying more than that?
Taken with a reversed 18-55 mm set lens
So, in this short article, I will certainly clarify exactly how to take high zoom macro photos making use of the lens turnaround method by turning around an 18-55 mm set lens. The tutorial is structured in the list below means:
Lens turnaround method for high zoom macro digital photography– Turning around an 18-55 mm set lens
What is high zoom macro digital photography?
There are several of complication regarding the zoom in macro digital photography. The majority of people obtain puzzled with the lingos like zoom proportion, life-size zoom, and also numbers like 1:1, 1:2, 2:1, 3:1, and so on. Or 1X, 3X, and so on. However it is quite easy. You require to recognize what these proportions indicate when you review or do something regarding macro digital photography. Several of you may believe, “why do I need to know the magnification ratio or all that mathematical stuff? If the subject is big enough in the photograph, then it would be fine” However, believe me, it will certainly assist you in mounting and also, furthermore, that would certainly assist you enhance your macro digital photography.
It is no brain surgery. A 1:1 zoom (life-size zoom) is recording real dimension of a topic. Claim, your video camera has a 23 mm sensing unit and also if you picture a topic which is 23 mm long, it will certainly fill up the whole structure. And also if you picture the topic at 1:2 zoom, after that the size of the topic would certainly be 11.5 mm in the picture. Therefore, a 2:1 zoom implies you are recording the subject two times its initial dimension. And also 1:2 zoom implies you are recording the subject fifty percent its initial dimension. Some lenses like tamron 70-300 mm deal 1:2 zoom where it allow you concentrate a little closer than regular lenses to obtain that zoom. A specialized macro lens provides atleast a 1:1 zoom. In a similar way, 1X implies the zoom is like that of the actual dimension of the topic, 2X implies two times the dimension of the topic, and so forth.
At 0.31 m and also 0.39 m concentrating range, you can catch at 1:1 and also 1:2 zoom specifically
What are the numerous approaches for high zoom macro digital photography?
I had actually made use of reversed 50 mm for macro digital photography prior to I began making use of the reversed set lens. Like I have actually discussed in the past, a reversed 50 mm lens will just provide a 1:1 zoom. Although it sufficed, I intended to attempt greater zoom. So, I sought out for numerous approaches to take high zoom macro digital photography and also discovered these:
- Devoted lens like canon MP-E 65 mm.
- Lens turnaround method with a focal size smaller sized than 50 mm (or much longer that 50 mm, yet I would not suggest that technique)
- Utilizing expansion tubes in addition to a committed macro lens or a reversed lens.
- Lens combining.
- A magnifier like Raynox DCR-250/150 in addition to a committed macro lens.
- Utilizing tiny lens (for extremely high zoom like 10 X or even more)
I determined to reverse my 18-55 mm lens to take some high zoom macros as a result of the adhering to factors:
- I can not pay for a committed lens.
- Radical light loss if I make use of lens combining or expansion tubes.
- I currently had a package lens.
- Package lens provides me the versatility to transform the zoom (1X -5 X).
So, all I needed to do was to acquire the reverse ring for my 18-55 mm set lens and also get going.
Just how to turn around an 18-55 mm set lens for high zoom macro digital photography?
I would certainly recommend you to review my earlier articles on reverse lens method because the actions are basically the exact same.
- A DSLR with a chopped sensing unit. I have not attempted turning around an 18-55 mm lens on a full-frame DSLR. And also I will not suggest you to utilize it because at 18 mm there will certainly be vignetting (dark edges aware). Nonetheless, because the efficient focal size of 18 mm in a 1.6 plant variable DSLR is 34 mm, you can turn around a lens with a minimum of 34 mm in a complete structure video camera. That would certainly provide the exact same zoom as 18 mm in a chopped sensing unit.
- A reverse ring for your 18-55 mm lens. The filter string size for 18-55 mm lens is 58 mm. So you require a reverse ring of that size.
Notification the 58 mm filter size
- An outside light. You require to make use of either your pop-up flash or an exterior flash as a light to make up for direct exposure loss. It is not simply that easy to make use of the flash and also obtain great outcomes. There is a lot to speak about lights and also it would certainly make this article hugely extensive. I will certainly clarify thoroughly regarding the lights in high zoom macro digital photography in an additional short article.
- Some tinted things, blossoms or leaves. This is for obtaining a tinted history in the picture. I will certainly clarify even more regarding this when I clarify lights and also direct exposure.
Following, I am mosting likely to clarify exactly how to utilize this arrangement to take high zoom macro photos and also exactly how to improve outcomes with a reversed 18-55 mm set lens.
Just how to gauge the zoom of a reversed lens?
The normal inquiry is, exactly how do you gauge the zoom once the lens is turned around. I have actually browsed a whole lot regarding this. What I can locate was that there is no outright means to gauge the zoom in macro digital photography. That is, there is no formula in which you can simply place your criteria and also obtain the zoom. All you can do is to make use of a leader, take photos at various focal sizes and after that learn the zoom. Nonetheless, I can be incorrect regarding this. So if you have an appropriate technique to gauge the zoom of a reversed lens, after that please share it with me.
F-number, zoom, and also deepness of area
The f-number, zoom, and also deepness of area relate. Comprehending this will certainly assist you make an excellent picture. Nonetheless, this is most complex component in macro digital photography and also it is multiplied backwards lens method and also much more in high zoom macro digital photography. You will certainly obtain puzzled regarding exactly how to establish the aperture or what aperture setup you need to make use of at various magnifyings to obtain sharp pictures. The normal error individuals make is neglecting the aperture setups when they make use of the reverse lens method. And also the outcome is an undistinct, obscured picture. So you need to recognize exactly how to select the aperture to obtain an appropriate deepness of area at various magnifyings. I can speak about this making use of some physics, maths and also whatever yet I recognize it is dull and also I do not intend to make you all lightheaded and also dislike shutterstoppers permanently. Besides, obtaining great outcomes does not require recognizing all those things. So, I am mosting likely to clarify it as easy as I can do, although there are some technological facets which need to not be ignored. I wish you do not curse me.
Just how deepness of area is connected to zoom and also f-number?
Deepness of area is merely the location of the picture in emphasis. So, a superficial deepness of area implies extremely tiny location in emphasis et cetera of the picture is obscured. The aspects that figure out the deepness of area are aperture, the zoom of the topic, the range in between the subject and also the sensing unit of your video camera. Therefore, by transforming these, you can transform the deepness of area. However the tale does not finish right here.
High zoom macro digital photography requires a great deal of light. This is since the efficient f-number modifications at high zoom as you require to make use of tiny f-number to obtain an appropriate deepness of area. As I discussed in the past, as the zoom boosts, the deepness of area reductions. At high zoom like 4X, the deepness of area will certainly be much less than 0.2 mm (that is the location in emphasis). So, to raise this deepness of area, you require to make use of tiny f-number because slim apertures raise the deepness of area. However, also at f16, the deepness of area is unsatisfactory to obtain the whole topic in emphasis. In such situations, there are 2 points you can do: either concentrate a fascinating component of the subject or make use of emphasis piling technique. Nonetheless, it is not recommended to quit down past f16 because it creates diffraction that makes the picture soft.
Currently you may be asking yourself why at tiny f-numbers you do not obtain huge deepness of area although you fire landscape photos at f16 and also obtain the full picture in emphasis. This is since the f-number you establish on your video camera is not actually the aperture setup at closer concentrating ranges (or when you contend high zoom). I think you may be taking out your hair currently. Allow me clarify. The F-number you embed in your video camera is for infinity concentrating range. When the concentrating range reductions, the zoom boosts. And also when you concentrate at close ranges, the f-number modifications. Therefore, the efficient f-number is connected to the zoom and also f-number you embed in your video camera. You can see this on your own. Establish the f-number to f14 and also transform the zoom from 1X to 5X. You can see that the viewfinder obtains darker when the zoom modifications from 1X to 5X and also the other way around.
Efficient F-number =f-number x (1+ zoom)
This is not a helpful formula to determine the f-number because there are numerous various other criteria included. This formula is simply to provide you a concept that f-number modifications with zoom. Nikon individuals recognize this facet greater than Sony and also Canon individuals because Nikon deal with efficient f-numbers. That is, Nikon transforms the aperture as you concentrate better while Sony and also Canon does not. This holds true when the lens remains in regular install. Backwards install, all brand names function similarly.
Therefore, high zoom causes superficial deepness of area, so you require usage slim apertures (tiny f-numbers) to obtain an appropriate deepness of area.
Altering the zoom while making use of a reversed 18-55 mm set lens
When the concentrating range reductions, zoom boosts. Normally, lenses have actually repaired brief concentrating range which is why you can not take macro photos making use of every lens. Devoted macro lenses have system to concentrate at close ranges. Partially 1 of this tutorial, I have actually revealed you exactly how the zoom modifications with the concentrating range. The concentrating range is transformed by:
- Altering the focal size of the lens.
- By an inner concentrating system. This method is made use of in devoted macro lenses like 90 mm, 100 mm, and so on. When you concentrate better making use of these lenses, the size of the lens does not transform.
So, at various focal sizes, you obtain various zoom. And also the concentrating range modifications, as well. Therefore, when the lens remains in reverse install, the concentrating range obtains much shorter when you transform the focal size from 55 mm to 18 mm because the zoom boosts.
Therefore, the benefit of making use of a reversed 18-55 mm lens is that you can transform the zoom (1:1 -5:1) by transforming the focal size. Aside from obtaining various magnifyings, an additional benefit is that you can locate the based on mount well. I will certainly clarify this in the following short article.
Every one of this info may bewilder you. So I believed I need to provide you the essence of this short article. This short article needs to provide you:
- A basic suggestion regarding deepness of area, f-number, and also zoom in high zoom macro digital photography.
- Sufficient info to establish the video camera setups (aperture setups at numerous magnifyings).
- A concept regarding exactly how to transform the zoom when the lens remains in reverse install.
