Do better quality lenses have a better 'quality' DOF?

asked on November 9, 2017
Hi All, I'd like to justify purchasing a fairly expensive prime lens. I want to take my 6D to the camera shop and try out 3 lenses to see if there is ...View More

First question is that how do you understand if a lens is of high quality and will produce quality DOF (better DOF).

I'd like to explain DOF as not dependant on lens quality but dependant on aperture number (f-number). Usually low f-number lenses are expensive like 85mm f/1.4 is pretty expensive than 85mm f/1.8 costlier. f/1.4 lenses are also termed as better quality lens due to their internal structure.

Let's try one thing. Keeping ISO and shutter same, shoot at f/2.5 with 85mm f/1.4 lens then shoot with 85mm f/1.8 lens. DOF will remain almost similar irrespective of the cost of the lens. But if you want to produce even better DOF with either lens, you will have to shoot at f/1.8 on 85mm f/1.8 lens and shoot at f/1.4 on 85mm f/1.4 lens. Now you will find you the background is very much smooth in that image which was shoot at f/1.4 on 85mm f/1.4. So the reason is lower f number produce better DOF.

DOF is not the only reason to buy expensive prime lenses. There are other factors as well:

1. f/1.4 lens will be fast than f/1.8 lens.

2. Ideal for low light situation.

3. Better quality image.

If you find above points reasonable to invest large amount, can go with it. I don't think so until you buy lenses, can try new lenses at shop. Though you can get them all on rent for a day to experiment if you like the performance. Then you choose to go with.

If I'm hobby photographer, I'd prefer to go with f/1.8 lens as it saves a lot.

Let's try one thing. Keeping ISO and shutter same, shoot at f/2.5 with 85mm f/1.4 lens then shoot with 85mm f/1.8 lens. DOF will remain almost similar irrespective of the cost of the lens. But if you want to produce even better DOF with either lens, you will have to shoot at f/1.8 on 85mm f/1.8 lens and shoot at f/1.4 on 85mm f/1.4 lens. Now you will find you the background is very much smooth in that image which was shoot at f/1.4 on 85mm f/1.4. So the reason is lower f number produce better DOF.

DOF is not the only reason to buy expensive prime lenses. There are other factors as well:

1. f/1.4 lens will be fast than f/1.8 lens.

2. Ideal for low light situation.

3. Better quality image.

If you find above points reasonable to invest large amount, can go with it. I don't think so until you buy lenses, can try new lenses at shop. Though you can get them all on rent for a day to experiment if you like the performance. Then you choose to go with.

If I'm hobby photographer, I'd prefer to go with f/1.8 lens as it saves a lot.

But if you want to produce even better DOF with either lens, you will have to shoot at f/1.8 on 85mm f/1.8 lens and shoot at f/1.4 on 85mm f/1.4 lens. Now you will find you the background is very much smooth in that image which was shoot at f/1.4 on 85mm f/1.4. So the reason is lower f number produce better DOF.

DOF is not the only reason to buy expensive prime lenses. There are other factors as well:

1. f/1.4 lens will be fast than f/1.8 lens.

2. Ideal for low light situation.

3. Better quality image.

If you find above points reasonable to invest large amount, can go with it. I don't think so until you buy lenses, can try new lenses at shop. Though you can get them all on rent for a day to experiment if you like the performance. Then you choose to go with.

If I'm hobby photographer, I'd prefer to go with f/1.8 lens as it saves a lot.

Now you will find you the background is very much smooth in that image which was shoot at f/1.4 on 85mm f/1.4. So the reason is lower f number produce better DOF.

DOF is not the only reason to buy expensive prime lenses. There are other factors as well:

1. f/1.4 lens will be fast than f/1.8 lens.

2. Ideal for low light situation.

3. Better quality image.

If you find above points reasonable to invest large amount, can go with it. I don't think so until you buy lenses, can try new lenses at shop. Though you can get them all on rent for a day to experiment if you like the performance. Then you choose to go with.

If I'm hobby photographer, I'd prefer to go with f/1.8 lens as it saves a lot.

First question is that how do you understand if a lens is of high quality and will produce quality DOF (better DOF).

I'd like to explain DOF as not dependant on lens quality but dependant on aperture number (f-number). Usually low f-number lenses are expensive like 85mm f/1.4 is pretty expensive than 85mm f/1.8 costlier. f/1.4 lenses are also termed as better quality lens due to their internal structure.

2. Ideal for low light situation.

3. Better quality image.

If you find above points reasonable to invest large amount, can go with it. I don't think so until you buy lenses, can try new lenses at shop. Though you can get them all on rent for a day to experiment if you like the performance. Then you choose to go with.

If I'm hobby photographer, I'd prefer to go with f/1.8 lens as it saves a lot.

First question is that how do you understand if a lens is of high quality and will produce quality DOF (better DOF).

I'd like to explain DOF as not dependant on lens quality but dependant on aperture number (f-number). Usually low f-number lenses are expensive like 85mm f/1.4 is pretty expensive than 85mm f/1.8 costlier. f/1.4 lenses are also termed as better quality lens due to their internal structure.

Let's try one thing. Keeping ISO and shutter same, shoot at f/2.5 with 85mm f/1.4 lens then shoot with 85mm f/1.8 lens. DOF will remain almost similar irrespective of the cost of the lens. But if you want to produce even better DOF with either lens, you will have to shoot at f/1.8 on 85mm f/1.8 lens and shoot at f/1.4 on 85mm f/1.4 lens. Now you will find you the background is very much smooth in that image which was shoot at f/1.4 on 85mm f/1.4. So the reason is lower f number produce better DOF.

First question is that how do you understand if a lens is of high quality and will produce quality DOF (better DOF).

I'd like to explain DOF as not dependant on lens quality but dependant on aperture number (f-number). Usually low f-number lenses are expensive like 85mm f/1.4 is pretty expensive than 85mm f/1.8 costlier. f/1.4 lenses are also termed as better quality lens due to their internal structure.

Let's try one thing. Keeping ISO and shutter same, shoot at f/2.5 with 85mm f/1.4 lens then shoot with 85mm f/1.8 lens. DOF will remain almost similar irrespective of the cost of the lens. But if you want to produce even better DOF with either lens, you will have to shoot at f/1.8 on 85mm f/1.8 lens and shoot at f/1.4 on 85mm f/1.4 lens. Now you will find you the background is very much smooth in that image which was shoot at f/1.4 on 85mm f/1.4. So the reason is lower f number produce better DOF.

DOF is not the only reason to buy expensive prime lenses. There are other factors as well:

1. f/1.4 lens will be fast than f/1.8 lens.

2. Ideal for low light situation.

3. Better quality image.

If you find above points reasonable to invest large amount, can go with it. I don't think so until you buy lenses, can try new lenses at shop. Though you can get them all on rent for a day to experiment if you like the performance. Then you choose to go with.

If I'm hobby photographer, I'd prefer to go with f/1.8 lens as it saves a lot.

But if you want to produce even better DOF with either lens, you will have to shoot at f/1.8 on 85mm f/1.8 lens and shoot at f/1.4 on 85mm f/1.4 lens. Now you will find you the background is very much smooth in that image which was shoot at f/1.4 on 85mm f/1.4. So the reason is lower f number produce better DOF.

DOF is not the only reason to buy expensive prime lenses. There are other factors as well:

1. f/1.4 lens will be fast than f/1.8 lens.

2. Ideal for low light situation.

3. Better quality image.

If you find above points reasonable to invest large amount, can go with it. I don't think so until you buy lenses, can try new lenses at shop. Though you can get them all on rent for a day to experiment if you like the performance. Then you choose to go with.

If I'm hobby photographer, I'd prefer to go with f/1.8 lens as it saves a lot.

Now you will find you the background is very much smooth in that image which was shoot at f/1.4 on 85mm f/1.4. So the reason is lower f number produce better DOF.

DOF is not the only reason to buy expensive prime lenses. There are other factors as well:

1. f/1.4 lens will be fast than f/1.8 lens.

2. Ideal for low light situation.

3. Better quality image.

If you find above points reasonable to invest large amount, can go with it. I don't think so until you buy lenses, can try new lenses at shop. Though you can get them all on rent for a day to experiment if you like the performance. Then you choose to go with.

If I'm hobby photographer, I'd prefer to go with f/1.8 lens as it saves a lot.

First question is that how do you understand if a lens is of high quality and will produce quality DOF (better DOF).

I'd like to explain DOF as not dependant on lens quality but dependant on aperture number (f-number). Usually low f-number lenses are expensive like 85mm f/1.4 is pretty expensive than 85mm f/1.8 costlier. f/1.4 lenses are also termed as better quality lens due to their internal structure.

2. Ideal for low light situation.

3. Better quality image.

If you find above points reasonable to invest large amount, can go with it. I don't think so until you buy lenses, can try new lenses at shop. Though you can get them all on rent for a day to experiment if you like the performance. Then you choose to go with.

If I'm hobby photographer, I'd prefer to go with f/1.8 lens as it saves a lot.

First question is that how do you understand if a lens is of high quality and will produce quality DOF (better DOF).

I'd like to explain DOF as not dependant on lens quality but dependant on aperture number (f-number). Usually low f-number lenses are expensive like 85mm f/1.4 is pretty expensive than 85mm f/1.8 costlier. f/1.4 lenses are also termed as better quality lens due to their internal structure.

Let's try one thing. Keeping ISO and shutter same, shoot at f/2.5 with 85mm f/1.4 lens then shoot with 85mm f/1.8 lens. DOF will remain almost similar irrespective of the cost of the lens. But if you want to produce even better DOF with either lens, you will have to shoot at f/1.8 on 85mm f/1.8 lens and shoot at f/1.4 on 85mm f/1.4 lens. Now you will find you the background is very much smooth in that image which was shoot at f/1.4 on 85mm f/1.4. So the reason is lower f number produce better DOF.

First question is that how do you understand if a lens is of high quality and will produce quality DOF (better DOF).

I'd like to explain DOF as not dependant on lens quality but dependant on aperture number (f-number). Usually low f-number lenses are expensive like 85mm f/1.4 is pretty expensive than 85mm f/1.8 costlier. f/1.4 lenses are also termed as better quality lens due to their internal structure.

Let's try one thing. Keeping ISO and shutter same, shoot at f/2.5 with 85mm f/1.4 lens then shoot with 85mm f/1.8 lens. DOF will remain almost similar irrespective of the cost of the lens. But if you want to produce even better DOF with either lens, you will have to shoot at f/1.8 on 85mm f/1.8 lens and shoot at f/1.4 on 85mm f/1.4 lens. Now you will find you the background is very much smooth in that image which was shoot at f/1.4 on 85mm f/1.4. So the reason is lower f number produce better DOF.

DOF is not the only reason to buy expensive prime lenses. There are other factors as well:

1. f/1.4 lens will be fast than f/1.8 lens.

2. Ideal for low light situation.

3. Better quality image.

If you find above points reasonable to invest large amount, can go with it. I don't think so until you buy lenses, can try new lenses at shop. Though you can get them all on rent for a day to experiment if you like the performance. Then you choose to go with.

If I'm hobby photographer, I'd prefer to go with f/1.8 lens as it saves a lot.
