Hi Pranit,
I suggest you don't buy any lens before you understand the technical part of photography. The three lenses you are looking for are for different purpose. First understand what they do and what you want to shoot. For e.g 70-300 is a telephoto zoom lens. This lens will bring the far object nearer. The 50mm with it's larger aperture will allow you to shoot in very low light. The macro lens allows you to focus closer to an object than other lenses so that they can fill your frame with the object. (You must have known that every lens has a minimum focusing distance).
Photography is just like painting. Other than being creative in painting the painter has to learn to use the tools. He has to understand the mixing of colours, the useage of different types of brush, different types of paper or canvas. Similarly in photography you have to learn the useage of tools like focal length, aperture, shutter, ISO and if you are shooting DLSR then learn to use raw files and process. You need to put an effort to understand all this things. After that you will really enjoy photography.
Sorry for such a long post.

I guess you missed the "manual focus lens" part!!!
Though they are expensive, they are cheaper than the 50K you were talking about!!
A brand new Nikon 50mm f/1.4 AI is around $400. While a used one would be from $75 to $150 for non-AI/AI (you may try keh!!)

A brand new Nikkor 50mm f/1.2 AI-s is $630 in adorama.com. The used ones dont depreciate much so expect a good asking price for it!! Looking at the used prices i felt, its better to buy a new one!! And its worth the investment. It shall retain the value!!

my requitments are :
i need a telefoto zoom lens 70-300mm..

a Micro lens..

and i am thinking weather i should get a 50mm lens or not..


yaa during Macro i use Manual Focusing..
it works way better than AF..

and i am ok with f1.8, (obviously looking at the price, i cant afford a f1.4 or f1.2 lens..)

If you are ok with 7x optical zoom, have a look at Nikon Coolpix P7000.

But if you are big jooom lover, you may try
Nikon Coolpix P100 (26x)
Panasonic FZ35/FZ38 (18x)
Canon SX30 IS (35x)

PS: Of all the above, the P7000 has the biggest sensor!!!

Hey friends,

I am looking for a replacement of my DSC H50 cam as that camera is no more with me, dont ask details.

the dsc h50 from sony cybershot had automatic iso depending on the mode you choose, 15 x optical zoom with different modes for the lens.

It was a point and shoot camera and i am not that well experienced with dslr.

Can you suggest something better within a budget of 25k?

hahhaaaaa, this is what happens when you ask opinions in online groups about spending money!!!!

First lets see what exactly your requirements are:


I heard the folks who are into macro, use the Manual focusing option more often than auto focus. If thats the case with you, yes you can look at some incredible lens via this route!!! Should I tempt you with f1.4 or f1.2???

that was a great discription guys..
i got what you want to say..
will head for it then..
but again a question then..
shall i get a zoom lens first or a 50mm ??
but i can afford a 50mm lens right now ..
what shall i do..
sorry for asking so many questions ..

In addition to what kkrk2 has mentioned, you should check out some portraits taken with the 50mm, You will be blown away by the BOKEH and contrast, you will get the film like affect that you can never get with an all rounder lens like the one you have. To put it in a sentence "There is absolutely no comparison at 50mm between the two", I use it almost 90% of the times for portraits, I have almost stopped using my 18-70 lens after I got the 50mm.

PS:- Just do a google image search using "nikkor 50mm f 1.8"

Whats the f number at 50mm on your 18-105??? 4?? 4.5???
The lens in question, the 50mm lens its f1.8 PERIOD


EDIT:
Well its unfair if I leave it there!! The 50mm f1.8 is a prime lens.

ok thank you guys..
i need VR because my hands a little bit shaky..
will check out the Tamron 90mm then..
and then as you guys have mentioned about a 50mm lens, i have heard about it from a few friends of mine, but then how is it different form a 50mm zoom by a 18-105mm lens...

I very much agree. Tamron is the best value for money. I have used it and also Nikon, the image quality of both is similar.
The Nikor 70-300 VR is the best among the variable aperture in that focal range. Alas! it is very expensive.
I recommend you get 50mm. Even an old manual lens will do. You will have a different avenue opened up for you in photography.

+1 to what hensil has mentioned. Also why don't u look at the tamron 90mm macro lens, should be available for 17k, the iq is very good, also I would advice u to buy the 50mm 1.8d for 5k, nothing beats it for portraits.
as for long zoom, the 70-300mm vr is a good buy over the 55-300.

If you are on a budget and have a D90(a blessing in disguise) and dont mind the lack of VR, you can consider Nikon 70-300mm f/4-5.6G (around 6,000/- brand new as per nikon india website!!)

Pranit,
Of course, it is worth buying used lenses provided they are functional and there is no fungus in it.
Now my question to you is, how much are you into macro photography? A dedicated macro lens can be expensive (even used). It's definitely worth it if you will be shooting lots of macro. Other option will be to buy a 50mm, f/1.8 and a reversing mount. When you use the lens in reverse it works as macro lens. Another option is to use 50mm reversed in front of your kit lens. For this you will need a reversing ring. If you will shoot macro occasionally, I would recommend this route because you can then use the 50mm independently to shoot in low light and take advantage of it's large aperture.
Henry

thank you guys..
@bprags.. i have the Kit lens 18-105..
no other lens ..
but i am planning to buy a 105 macro lens..
since a new 105mm lens would cost me around 50k, i was thinking of getting a second hand 105mm lens..
what do you say..
is it worth buying a Second hand lens..
