6 Tips To Choose A Perfect Lens For Your Camera!

Friday, February 9th, 2018


which lens

A camera helps to capture the world around and a lens is what plays the main role to help you do that perfectly. The quality and the type of lens surely make a difference in the image captured. Whether it is about buying a dash cam or a nanny cam with audio, if you are deciding to add a new camera to your kit, just read these tips to help you choose the perfect lens.

  1. 1.      What do you want to shoot?

This is the first and the most basic question that should be asked before you jump into the technical specifications of the lens. The type of lens you should buy depends on what you are going to shoot with it, whether it is landscapes, portraits, architecture, birds, wildlife, sports or other subjects.


  1. 2.      Decide the budget

Cost is of course, always a factor to be considered. Cost of a lens depends on the aperture, focal length, and other specifications. An expensive lens has a fixed aperture i.e.  no matter how much you zoom the aperture remains fixed, unlike the less expensive ones which have a variable aperture. A variety of lens is available to suit the budget and the aperture and focal length requirements.


  1. 3.      Aperture of the lens

The aperture of a lens determines how much light can the lens let in and is a number written on the lens.

  • Wide aperture: Smaller the number, wider the aperture. A wide aperture captures more light and hence can take photographs even when the light available is less but makes the image less sharp.
  • Narrow aperture: Larger the number, narrower the aperture. In contrast to the wide aperture lens, it captures less light but provides a greater depth of the field.


  1. 4.      Focal length

It determines how far can you zoom in. Larger the number more will be the magnifying power of the lens. It is a prominent aspect of a lens irrespective of whether you are going for a dash cam or a nanny cam with audio.


  1. 5.      Stabilization

Having a stabilized lens is an expensive deal but it lets you take sharp shots even in varying lighting conditions and eliminates camera shake.


  1. 6.      Perspective

Visual perspective is, of course, an important part when you wish to tell a story through your capture. It may happen that when you are shooting a tall building and you shift the lens upward, the building shape gets distorted showing a thinner top and a wide bottom, unlike the reality. This simply means the perspective being captured is not correct and hence a lens needs to be such that it can correct the perspective and show the true picture.


Buying a lens for your camera is a huge investment. Once you have invested in the camera, the next is the lens which should be chosen wisely and the above tips will definitely help. Follow the tips and save yourself from the regret which may follow a wrong purchase!

Lens Sony 85mm Block
Mount E mount
F 1.4
Min focus distance 80cm
Blades 11



Sony E mount 85mm G master Block lens gives great sharpness and Bokeh & capture great details. So it’s a great lens.


Advantage of Sony E mount lens

-          Native AF system.

-          Benefits from all of Sony’s features including Eye AF

-          Works perfect with Sony A7s II, Sony A7R II, A7R, A7s etc.


AF / MF switch

-          AF/MF switches

-          Programmable Fn button (defaults to Focus Hold).

One can set the button to activate Eye AF for natural and easy access to the setting during use.



-          Rubberized focus ring helps you operate the lens smoothly

-          Improved focus-by-wire system helps these lenses to have a more natural feel does not seem to ramp up or down in speed depending on how fast you turn it.


Aperture ring

-          The integration of a physical aperture ring, allows to be clicked or de-clicked with a switch which makes it a great option for video shooters, as well as photographers.


Physical details

-          The small ridge on the bottom of the lens ensures that the lens’s aperture and focus rings are not lying directly on any surface when the camera is laid down.


Some Cons

The lens is slower than other native options due to the use of an older, and louder, Linear SSM system to move the large elements precisely, which could be changed by using the Direct Drive SSM available in many current models.


Chromatic Aberration at F1.4

There is a noticeable amount of chromatic aberration on high-contrast edges at f/1.4 which could of course be easily corrected in post


Tips : It gets better as you stop down, peaking at about f/4-5.6, where it will optimize the performance. Vignetting is also very well controlled and flare is nonexistent.


Focus Ring

There are still no witness markings on the lens and no hard end stops which makes them less appealing for use with follow and remote focus units.

They would work well with smaller handheld gimbals rather than larger Steadicams and gimbals


Canon 100-400 mark II – salient features

Monday, July 18th, 2016


Canon 100-400 mark II

 3 modes of IS

Mode 1 -  Standard IS mode designed for use with stationary subjects when the Canon 100-400 IS ii & the camera is handheld

Mode 2 – is used for panning with a subject. In this mode, only 1 axis of stabilization is provided – allowing a linearly-moving subject to be tracked. Up and down movement tend to be difficult to track

Mode 3 – is great for action photography. In Mode 3, image stabilization is active and ready for use the moment the shutter releases, but actual stabilization is not in effect until that precise time. You are able to follow your erratically-moving subjects without fighting against image stabilization   The IS system auto-senses a tripod in use

Quick Auto focus The zoom is a quick performer, taking about 0.15 seconds to lock onto the subject when mounted on the Canon EOS 5D Mark III.


A completely new inner-focusing system has been implemented in this lens.

A 2-position focus limiter switch is provided, allowing focusing distances to be limited to a specific distance range (9.84′/3m – 8) – or to be unlimited (Full). Limiting the focus distance range can improve focus lock times and reduce focus hunting.

This lens is not parfocal, meaning that refocusing is required after zooming. This is especially true at short focus distances where the subjects very obviously go into and out of focus during zooming. Using the near-parfocal feature of this lens is helpful for video recording while adjusting focal lengths. Video shooters will definitely appreciate the fact that subjects do not significantly change in size as they go in and out of focus

Polariser users will be happy that the 77mm filter thread doesn’t rotate on focus.

Decreased Minimum Focus Distance (MFD) This lens has an MFD of 980mm. (earlier lens MFD was 1800mm)

Increased Magnification This lens has a magnification of 0.31x. (earlier lens MFD was 0.2x)

Build –  This is a solidly built lens

The 100-400 II’s front and rear lens surfaces are fluorine coated to reduce water droplet, dust and fingerprint adhesion and to ease the cleaning effort required. This coating works great – the difference is noticeable.

Push Pull Zoom replaced with rotational zoom -  The rotating zoom ring gives more precise adjustment between focal lengths. The ring comes with a zoom torque adjustment ring allowing you to set the zoom ring from “Smooth” to “Tight” to suit your particular way of shooting.

The final control on the lens barrel is a focus mode switch with the usual AF/MF settings. Note that this lens usefully offers full-time manual focusing even when AF is selected.

Lens elements It has 21 lens elements in 16 groups (up from 17/14) into a telephoto lens design

Air Sphere Coating The new Air Sphere Coating (ASC) had been introduced on this lens. According to Canon: “The new Air Sphere Coating has been developed by Canon to minimise reflections and flare.

In the nutshell : The Canon EF 100-400mm f/4.5-5.6L IS II is a worthy replacement to the original 100-400. Not to forget the original 100-400 continues to be a great lens.

Tripods and tracks give great steady images but are they practical always?

Wednesday, May 4th, 2016


Time : Setting a track trolley and tripod needs time and space.                                     

Cost : Once you give a miss to the tripod, track, trolley and jib, you
save lots of money due to savings on costs of attendants, technicians,
production vehicles, etc. Indirect savings include decreased conveyance,
stay and food of the manpower.

Nimble is faster : A smaller crew is always nimble. Fewer heads, fewer confusions, higher efficiency

Effect : Shooting handheld gives a new feel. When we see the Tv series ‘24’ or the Bourne Series, we get the fast paced feel. A lot of that is shot handheld.

Less Intrusions : Often Police & security guards don’t interfere when you shoot handheld.

More convenient in weddings, offices, travel shoots etc
While shooting weddings and city offices setting a tripod is not always possible. Tracks could damage the furniture or inconvenience the people around.

Shoot Professionally without a Track & a Tripod

Beware !
Shooting handheld can be tricky and can make the work look amateurish.


Depth of field in camera lenses – Simplified

Friday, April 29th, 2016



Depth of field is the zone of acceptable sharpness within a photo that will appear in focus. In every picture there is a certain area of your image in front of, and behind the subject that will appear in focus.

This zone will differ from photo to photo. Some images may have very small zones of focus which is called shallow depth of field.

Others may have a very large zone of focus which is called deep depth of field.

3 main factors that will affect how you control the depth of field of your images are:

aperture (f-stop),

distance from the subject to the camera, and

focal length of the lens on your camera.
